    In such an installation, some home automation devices communicate according to a first type of protocol, in particular a local protocol of the home automation protocol type, for example a proprietary protocol that does not use IP addressing. Other equipment or other home automation devices in the same installation may communicate according to target communication protocols of a second type, in particular in a communication protocol over the IP protocol, or a generic point-to-point protocol, for example Bluetooth.
    The presence of different communication protocols does not allow easy communication between devices or requires the provision of the implementation of several communication protocols on devices and equipment to enable their communication, which increases the cost and / or complexity of the programming of these.
    The present invention aims to solve all or part of the disadvantages mentioned above.

U. Only two home automation devices D1, D2 communicating according to the first local communication protocol P1 are shown in FIG. 4. However, a single home automation device or a number greater than two of home automation devices can also be considered.
    In a first step EcfUl, the configuration method can be triggered by receiving an Mlnit message received by the central control unit U from a user terminal Usr / T which transmits it in an EcfTl step. Alternatively, pressing a button of the central control unit U may also allow the triggering of the process. Alternatively or in addition, an action on a home automation device, such as pressing a button can be considered.
    In a step ECfU2, the central control unit U sends MD discovery messages to the domotic devices D1, D2 according to the first communication protocol PI, which receive this message MD respectively in steps EcfD12 or ECfD22.
    In steps EcfU3, EcfU4, the central control unit U receives configuration messages MCfD1, MCfD2 from the home automation devices D1, D2 which issue these messages respectively in steps ECfD12 and ECfD22.
    Each of these configuration messages MCfD1, MCfD2 is relative to a location identifier P1AD1, P1AD2 of a home automation device D1, D2 according to the first local communication protocol PI and to: a type P2TD1, P2TD2 of the at least one home automation device D1, D2; and / or o at least one definition of a function P1F1D1, P1F2D1, P1F1D2, P1F2D2 or a group of functions of the at least one home automation device D1, D2 according to said first communication protocol PI and / or o at least a definition of a state variable P1S1D1, P1S2D1, P1S1D2, P1S2D2 or of a group of state variables of the at least one home automation device D1, D2 according to said first communication protocol PI;
    In a step ECfU5, the central control unit U obtains a location identifier P2AD1, P2AD2 for each home automation device D1, D2 according to a second target communication protocol P2. The methods for obtaining the location identifier can be multiple and are detailed later.
    In a step Ecf6, the control unit can verify the existence of at least one RCFX function conversion rule arranged to convert the definition of the at least one function P1F1D1, P1F2D1, P1F1D2, P1F2D2 according to the first communication protocol PI in at least one definition of a function P2F1D1, P2F2D1, P2F1D2, P2F2D2 according to the second target communication protocol P2 and / or a state conversion rule RCSX arranged to convert the definition of at least one state variable P1S1D1, P1S2D1, P1S1D2, P1S2D2 according to the first communication protocol PI into at least one definition of a state variable P2S1D1, P2S2D1, P2S1D2, P2S2D2 according to the second target communication protocol P2.
    This check may be based on the type of device P2TD1, P2TD2, or the definitions of functions, function groups, and / or the definitions of state variables or groups of state variables. In fact, depending on the protocols used, a type may be sufficient to identify the functions or state variables supported, for example in the homecontrol protocol, or functions or groups of functions or variables or groups of state variables must be listed, as for example in the Zwave protocol.
    Alternatively, the central control unit U may identify a correspondence between a home device device type P1TD1, P1TD2 according to the first local communication protocol PI and a home device device type P2TD1, P2TD2 according to the second local communication protocol P2.
    The conversion rules can be stored in one or more correspondence tables, included in a knowledge base.
    In the case where such a conversion rule is not available, the central control unit can obtain it, for example by downloading from the server Sv. Thereafter, the conversion rules can be be saved in an EcfU6 step.
    The implementation of the conversion of a function may also include a step of defining an action to be performed at least partially by the central control unit in correspondence with a function according to the second protocol corresponding to a location identifier, or the limitation of the function requested or the prohibition of a function to be performed. Alternatively, the corresponding definitions may be predefined in the correspondence table or knowledge base.
    The conversion of the functions or state variables can alternatively be implemented as part of the control and / or supervision method.
    Examples of conversion or partial realization by the central control unit are given later in the context of the description of the control method or supervision.
    In a step ECfU7, the central control unit U records the correspondence between the location identifier P1AD1, P1AD2 of the at least one home automation device D1, D2 according to the first communication protocol and the location identifier P2AD1, P2AD2. the at least one home automation device D1, D2 according to the second communication protocol P2 in a node table illustrated in FIG. 6;
    In a step EcfU8, the central unit U also records in the node table: the at least one type P2TD1, P2TD2 of the at least one domotic device D1, D2; and / or the at least one definition of a function P1F1D1, P1F2D1, P1F1D2, P1F2D2 or a group of functions of the at least one domotic device D1, D2 and / or the at least one definition of a state variable P1S1D1, P1S2D1, P1S1D2, P1S2D2 or a group of state variables of the at least one domotic device D1, D2; and / or an RCFX function conversion rule arranged to convert the definition of the at least one function P1F1D1, P1F2D1, P1F1D2, P1F2D2 or function group according to the first communication protocol PI into at least one definition of a P2F1D1, P2F2D1, P2F1D2, P2F2D2 or a function group function according to the second target communication protocol P2 and / or a status conversion rule RCSX arranged to convert the definition of the at least one variable of state P1S1D1, P1S2D1, P1S1D2, P1S2D2 according to the first communication protocol PI in at least one definition of a state variable P2S1D1, P2S2D1, P2S1D2, P2S2D2 according to the second target communication protocol P2.
    Once the configuration process steps have been performed, the domotic device DI is virtualized. The central control unit U can act on behalf of DI on the network R2.
    variants
    According to one variant, a device group can be identified by the same location identifier according to the second protocol. The correspondence table in this case comprises several location identifiers according to the first communication protocol that correspond to the same location identifier according to the second communication protocol. These arrangements make it possible to envisage configuring a group of controllable device as a single device, in a powerful manner by a single function call.
    Alternatively, the method includes a plurality of configuration message receiving steps corresponding to a plurality of first communication protocols.
    According to a variant, the method comprises a plurality of discovery message transmission step according to a plurality of first communication protocols.
    According to a variant, the method comprises a plurality of correspondence between a device communicating according to the first communication protocol and location identifiers according to several second control methods. For example, the second target communication protocols may be Weave / thread and Bluetooth.
    According to one variant, depending on the first communication protocol PI considered, it may be necessary for the central control unit U to send a registration message M1 in a step ECfU5 'in order to subscribe to notifications relating to at least one state variable of at least one home automation device D1, D2, the home automation devices receiving this message respectively in steps EcfD15 ', EcfD25'. Thus notifications concerning the state variables will be communicated to the central control unit as part of a supervision process.
    Obtaining a location identifier according to the second target communication protocol Obtaining a location identifier according to the second target communication protocol, that is to say a unique identifier in the local network under consideration goes to present be described according to two modes of implementation.
    In the case of the first local communication protocol, it is possible in particular to use as a location identifier an address in a proprietary format corresponding to the home automation protocol used.
    In the case of the second target protocol, a location identifier may in particular be a network address, for example an IPv4 or IPv6 address or a bluetooth address, or a composition of a network address and a resource identifier indicated by a path, for example in the form of the following URL: <protocol>: // <host address> [: <port>] / <resource path>
    We describe below two modes of implementation in which the location identifier corresponds respectively to a network address or to a combination of a network address and a resource.
    According to a first embodiment, the second target communication protocol involves the use of separate network addresses for home automation devices. In this case, the location identifier corresponds to a network address.
    According to a first possibility, the network address is equal to, or contains, the physical address of the device, for example in the case of a Bluetooth or IPv6 Link-local protocol. In this case, in a first step, the central control unit U determines a unique physical address for the device DI to be emulated.
    According to a first example, in the case of a protocol based on the IP protocol, the central control unit U can choose a MAC address in a range previously acquired from the IEEE registration organization, the address corresponding to a composition :
    Companyjd + free suffix
    In which: - companyjd corresponds to a manufacturer identifier, for example 3 bytes; free suffix, corresponds to a unique identifier of the device DI on the network R2, for example on 3 bytes. For a central control unit U which could emulate up to 255 home automation devices, it is sufficient in this case to vary the last byte to identify home automation devices D.
    According to a second example corresponding to an emulation according to the Bluetooth protocol, it is also possible to choose an address in a previously acquired range as described above for the MAC address as part of an IP protocol. In the same way, for a central control unit U which could emulate up to 255 home automation devices, it is sufficient to vary the last byte to identify the domotic devices D.
    In a second step, the central control unit U determines a unique network address from the physical address.
    According to some second P2 target protocols, the network address corresponds to the physical address, for example in the Bluetooth protocol. According to other second P2 target protocols, the network address is obtained by applying an injective transformation from the physical address, as for example in the case of the IPv6 Link-local protocol, in which the network address is constructed to from the MAC address.
    According to a second possibility, the network address is obtained from a network controller on presentation of a physical address. For example, this may be the case in a protocol above IP.
    According to this second possibility, in a first step, the central control unit U determines a unique physical address for the device DI to be emulated, similarly to the first mentioned possibility. In a second step, the central control unit U obtains a unique network address on the network R2 from a physical network address of a network controller. For example, the network controller may be a DHCP Server for IPv4 or IPv6.
    According to a second mode of implementation, the network address can be mutualizable for several domotic devices D1, D2. In this case the location identifier corresponds to a composition of a network address and a resource identifier indicated by a path. In this case, it may be sufficient to obtain a network address for the central control unit U.
    The different home automation devices are then associated with different resources corresponding to separate paths. By way of example, considering a protocol of the OlC / lotivity type, by obtaining for the central control unit a 192.168.0.2 address, it is possible to assign the identifiers of two lighting type devices as follows: oc: //192.168.0.2: 1234 / light / l oc: //192.168.0.2: 1234 / light / 2
    Resource / light / 1 is assigned to the first lighting device. Resource / light / 2 is assigned to the second lighting device.
    Variant
    According to one variant, the step of obtaining the location identifier may correspond to a reception of a user input of a location identifier according to the second communication protocol as represented in FIG. step ECfU2 '.
    According to one variant, the step of receiving a configuration message comprises a declaration by the user of the location identifier according to the first communication protocol and / or a declaration by the user of at least one function or of a type of device according to the first communication protocol as represented in FIG. 4 by the step ECfU2 '.
    Discovery process
    First mode of implementation
    We will now describe a first embodiment of a method of discovery of a home automation system 17 with reference to FIG. 7. We will assume here that the configuration method as described in FIG. to obtain the configuration shown in Figure 3.
    The method is executed by the central control unit U. Only two nodes NI, Nk communicating according to the second target communication protocol P2 on the network R2 are represented in FIG. 7. However, only one node or a number greater than two of nodes can also be considered.
    In a step EDU1, the central control unit U sends a message announcing MACD1 compatibility or declaration of existence in relation to a location identifier P2AD1, a first domotic device DI to at least one destination. NI node communicating according to the target communication protocol P2. The localization location identifier P2AD1 of the at least one domotic device DI according to the second communication protocol P2 corresponds to the identifier of P1AD1 of the domotic device DI according to the first communication protocol PI. The correspondence between the identifiers P1AD1 and P2AD1 is stored in a node table given during the configuration process.
    Subsequently, in a step EDU2, the central control unit U receives a discovery message MD, transmitted by a node according to the second communication protocol P2 in a step EDN12.
    In an EDU3 step, the central unit sends a description message MDescl according to the second target communication protocol P2 in relation with a type P2TD1 of the domotic device DI or at least one description of a function P2F1D1, P2F2D1 or of a group of function according to the second communication protocol P2 and / or of at least one state variable P2S1D1, P2S2D1 or of a group of state variable of the domotic device DI according to the second communication protocol P2.
    The same steps EDU4 to EDU6, corresponding to steps EDU1 to EDU3, are repeated for the second home automation device D2.
    Thus, in an EDU4 step, the central unit sends a MACD2 compatibility announcement message in relation to a P2AD2 location identifier of the second home automation device D2 to at least one communicating NI node according to the P2 target communication protocol. . The location identifier P1AD2 of the home automation device D2 according to the first communication protocol corresponds to the location identifier P2AD2 of the at least one home automation device D2 according to the second communication protocol P2. The correspondence between the identifiers P1AD2 and P2AD2 is stored in a node table entered during the configuration process.
    Subsequently, in a step EDU5, the central control unit U receives a discovery message MD, transmitted by a node according to the second communication protocol P2 in a step EDN15.
    In a step EDU6, the central unit sends a description message MDesc2 according to the second target communication protocol P2 in relation with a type P2TD2 of the home automation device D2 or at least one description of a function P2F1D2, P2F2D2 according to the second protocol of P2 communication and / or at least one state variable P2S1D2, P2S2D2 home automation device D2 according to the second P2 communication protocol.
    Thus, a publication of a location identifier according to the second communication target protocol is performed for home automation devices D1, D2 which are only able to communicate according to a first local or proprietary protocol.
    According to one variant, the MACD1, MACD2 compatibility announcement message and the description message MDescl, MDesc2 can be confused and sent without waiting for the reception of a discovery message.
    According to one variant, the MACD1, MACD2 and / or the description message MDescl, MDesc2 may be sent periodically to the nodes of the network R2.
    Second mode of implementation
    According to a variant of the discovery method described in FIG. 8, the central control unit waits in a step EDU1 'for the reception of a discovery message MD' according to the second communication protocol P2 sent by a node NI in a step EDN11 'for sending a first message announcing compatibility and description MDescl' in a step EDU2 'according to a second target communication protocol P2 in relation to the location identifier P1AD1 of the first domotic device DI and comprising: a type P2TD1 of the domotic device DI or at least one description of a function P2F1D1, P2F2D1 according to the second communication protocol P2 and / or at least one description of a state variable P2S1D1, P2S2D1 of the domotic device DI according to the second communication protocol P2.
    In the same way, the central control unit sends in a step EDU3 'a second message of announcement of compatibility and description MDesc2' according to the second target communication protocol P2 in relation to the location identifier P1AD2 of the first device home automation system D2 and comprising: a type P2TD2 of the home automation device D2 or at least one description of a function P2F1D2, P2F2D2 according to the second communication protocol P2 and / or at least one state variable P2S1D1, P2S2D1 of the home automation device DI according to the second P2 communication protocol.
    In this implementation mode, the compatibility and description announcement messages are merged. They can also be distinct as in the first mode of implementation.
    Variant
    According to one variant, the central control unit U can periodically check the availability of the home automation devices and send description and / or declaration of existence messages only if the home automation device concerned is available.
    Control method
    First mode of implementation
    We will now describe a first embodiment of a control method of a home automation system 17 with reference to FIG. 9. We will assume here that the configuration method as described in FIG. to obtain the configuration shown in Figure 3. We will assume that a discovery method as described in Figure 7 or Figure 8 has also been performed.
    The control method is executed by the central control unit U. Only one communicating NI node according to the second target communication protocol P2 on the network R2 is represented in FIG. 9. However, a single node or a number greater than two of nodes can also be considered. In the same way, only a domotic device DI communicating according to the first local protocol PI is shown but other devices may be present.
    In an optional prior ECUO step, a connection can be established between the node between a communicating NI node according to the second communication protocol P2 and the central control unit U, the central control unit U acting on the network R2 as virtual representative of the home network devices RI communicating according to the first local communication protocol PI.
    In a first step ECU1, the central control unit U receives at least one control message P2MC from a communicating node N1 according to the second communication protocol P2. The control message P2MC which is sent by the node NI in a step ECN11 comprises at least one location identifier P2AD1 of a home automation device DI according to the second target communication protocol P2 and at least one definition of a function P2F1D1 of the device DI home automation according to the second P2 communication protocol. In the present case, we will assume that the device concerned by the command is the device DI identified by the location identifier P2AD1, that the function concerned is a function P2F1D1 intended for this single home automation device.
    In a step ECU2, the central control unit U determines a location identifier P1AD1 of the domotic device DI according to the first communication protocol corresponding to the location identifier P2AD1 of the at least one domotic device DI according to the second protocol of P2 communication received in the P2MC command message.
    In a step ECU3, the central control unit applies an RCFX function conversion rule arranged to convert the definition of the function P2F1D1 according to the second target communication protocol P2 into at least one definition of a function P1F1D1 according to the first protocol PI local communication. For this, the central control unit U can use the correspondence table entered during the configuration process. The step of applying a conversion rule may comprise performing processing steps that are complementary to the call of the command, in particular if part of the function can not be performed on the home automation device, and in particular a partial enrichment of the function, or the limitation of the function requested or the prohibition of a function to be performed. For example, a planning of a command can be provided if the device itself does not allow such planning. Thus, it is possible to implement on the central control unit a function of the type "Calendar Weave" to trigger an opening command on Monday at 8:00 for a home automation device type store. Also as an example, a parameter conversion can be performed by the central control unit. A
    In a step ECU4, the central control unit U sends at least one control message P1MC to the at least one domotic device DI corresponding to the location identifier P1AD1 and the function P1F1D1 according to the first communication protocol local PI.
    In an ECD15 step, the domotic device DI executes the function P1F1D1.
    In a step ECU6, the central control unit U receives ECU6 an RP1MC command return message sent by the domotic device DI in a step ECD16 according to the first local communication protocol PI.
    In a step ECU7, the central control unit U applies a function conversion rule RCFX in order to convert a command feedback information P1RC expressed according to the first local communication protocol PI into a control return information P2RC expressed according to the second target communication protocol P2.
    In a step ECU8, the central control unit U sends at least one RP2MC command feedback message to the node N1 comprising a P2RC control return information according to the second communication target protocol P2.
    variants
    According to one variant, the central control unit U can receive a control message P2MC corresponding to a group command intended for a set of domotic devices identified by a set of location identifiers. In this case, a plurality of control messages P1MC are sent to the control devices concerned, after conversion of the function concerned and the location identification for each device. Subsequently, the central control unit may optionally aggregate the results or return communicated by the domotic devices D so as to return a unique P2RC command return message. For example, it can be agreed that the command is deemed successful if all the individual function implementations have a positive return, or failed if one of the functions for a home automation device returns a failure value.
    According to another variant already mentioned in the context of the configuration method, a device group can be identified by the same location identifier according to the second protocol. The correspondence table in this case comprises several location identifiers according to the first communication protocol that correspond to the same location identifier according to the second communication protocol. In this case, it is possible to proceed as described above for the group order. A plurality of functions according to the first local communication protocol are sent to the relevant devices corresponding to the plurality of location identifiers according to the first communication protocol, then the returns are stored and then aggregated to return a single result for the control message considered. .
    Supervision process
    We will now describe a first embodiment of a method of supervising a home automation installation 17 with reference to FIG. 10. We will assume here that the configuration method as described in FIG. to obtain the configuration shown in Figure 3. We will assume that a discovery method as described in Figure 7 or Figure 8 has also been performed.
    The supervision method is executed by the central control unit U. Only one communicating NI node according to the second target communication protocol P2 on the network R2 is represented in FIG. 10. However, a single node or a number greater than two of nodes can also be considered.
    In the same way, only a domotic device DI communicating according to the first local protocol PI is shown but other devices may be present.
    In an ESU2 step, the central control unit receives a P1MS supervision message sent by a domotic device DI in an ESD12 step, the P1MS supervision message comprising information relating to a value of at least one state variable P1S1D1 of the at least one domotic device DI according to the first communication protocol PI. The step ESU2 may be successive to a first step ESU1 of sending an interrogation or polling message, received by the domotic device DI in an ESD11 step. Alternatively, the sending of the P1MS message can be initiated by the domotic device DI autonomously, for example by detecting an event modifying the value of a state variable P1S1D1. The sending of the P1MS message can be carried out undifferentially to a set of nodes present on the communicating network according to the first communication protocol. This arrangement corresponds to the so-called "broadcast" mode. According to an alternative implementation mode, the home automation device can send the supervision message only to the nodes registered on the network established according to the first communication protocol, and in particular to the central control unit if it is registered. In this case, the central unit performs a preliminary step of sending to a domotic device DI a request for registration in an event subscription list relating to the at least one state variable P1S1D1. of the domotic device Dl.
    In an ESU3 step, the central control unit applies a RCSX state conversion rule to convert the at least one item of information relating to a value of at least one state variable P1S1D1 of the at least one device. home automation D1 expressed according to the first local communication protocol PI in a value of at least one state variable P2S1D1 of the home automation device D1 expressed according to the second target communication protocol P2.
    In a step ESU4, the central control unit adapts the location identifier P1AD1 of the at least one home-automation device P1AD1 according to the first communication protocol P1 into a location identifier P2AD1 of the home-automation device P2AD1 according to the second communication protocol P2. The steps ESU3 and ESU4 steps of applying a conversion and address adaptation rule can be performed sequentially in an indifferent order or simultaneously.
    In a step ESU6, the central control unit sends a P2MS supervision message to the communicating NI node according to a second communication protocol P2, the P2MS supervision message comprising information relating to a value of at least one variable d state P2S1D1 of the domotic device DI according to the second target communication protocol P2 and being in relation with the location identifier P2AD1 of the domotic device DI according to the second communication protocol P2.
    According to one possibility, the sending of the P2MS supervision message can be carried out at the initiative of the central control unit U spontaneously or following the reception of a P1MS supervision message from a home automation device D1. . According to another possibility, the P2MS supervision message can be sent following the reception by the central control unit U in a step ESU5 of an MQ request message sent in an ESN15 step from a network node N1. R2. According to this second possibility, the central control unit U comprises a space or storage basis of the state variable values for the domotic devices attached thereto.
    In the context of a direct sending on the initiative of the central unit U, the sending of the P2MS supervision message can be carried out undifferentially to a set of nodes present on the network communicating according to the second communication protocol P2 . This arrangement corresponds to the so-called "broadcast" mode. According to an alternative implementation mode, the central control unit can send the supervision message only to the nodes of the network R2 registered in a subscription list, and in particular to the node NI. In this case, the node NI performs a preliminary step of sending to the central control unit U of a registration request in an event subscription list relating to the at least one state variable P2S1D1 of the home automation device Dl.
    Variant
    According to one variant, the supervision method can be adapted to a control point. In this case, the command is identified and is notified to the central control unit as a modification of a state variable.
    According to one variant, the above-mentioned polling step ESU1 makes it possible to implement an event mode emulation for a device that does not offer such a functionality, in which the central control unit U can periodically consult the values of variables of the type. state of the devices, detecting the changes of values of state variables by comparing the last value obtained and the data or data it has previously stored and send, in case of modification, a P2MS supervision message relating to the variable d state modified to an NI node subscribed to the changes of this state variable.
    Examples
    Example 1
    A first example concerns a domotic device DI of the temperature sensor type. This sensor communicates according to a first local protocol PI type IO-homecontrol and is intended to be made accessible as a sensor according to the second communication protocol P2 type Bluetooth Low Energy.
    During the process of configuring or pairing the IO-homecontrol sensor with the central control unit U, in the configuration message MCfD1, the home automation device D is described as a system sensor of the type 0x03 (outside temperature sensor, unit : K) with a location identifier in the form of a network address 0x485670. The central control unit is registered with the home automation device D (sensor 10) to receive events relating to the variation of the measured temperature, which corresponds to a state variable P1S1S1 of the device. The central control unit then automatically determines a standard Bluetooth type or profile to be used to publish this device using a lookup table. In particular the corresponding profile identified is "Service Environmental Sensing" (org.bluetooth.service.environmental sensing / 0xl81A) with a published state variable definition "Temperature" (org.bluetooth.characteristic.temperature / 0x2A6E) according to a unit : ° C (integer / resolution 0.01). The central control unit then proceeds to the determination of a location identifier P2D1A of a free Bluetooth address for the device corresponding to the step ECfU6. In particular, this network address may consist of first 5 static bytes corresponding for example to a manufacturer prefix and a number or identifier of the central control unit U, and a free byte whose value identifies the device Dl. For example, the central control unit can choose the address 00: 12: 34: 56: 78: 01. The central control unit U proceeds in a step ECfU7 / ECfU8 to the recording of the correspondence of the type of device according to the first and the second protocol P2 and the location identifier correspondent according to the first and the second protocol in the table of nodes.
    The discovery process is then implemented.
    In a first step EDU1, the central control unit U sends a message announcing MACD1 and description MDescl of the domotic device DI as a new virtual device according to the second communication protocol P2 on the Bluetooth network R2.
    In the case of a Bluetooth protocol, the central control unit U can implement a bluetooth server GATT (Generic Attribute Profile) which announces the device DI at regular intervals. On receipt of such a message, an NI node constituting a Bluetooth client, for example a telephone or a tablet, can then establish a point-to-point connection with the central control unit U to control or receive data from the virtual device.
    The supervision or control method can then be implemented.
    Thus, when a radio event transmitted by the sensor is received by the central control unit from a location identifier according to the first communication protocol PI (here an address 0x485670), the latter determines the identifier corresponding location according to the second P2 communication protocol using the node table. In this example, the address returned here is Bluetooth 00: 12: 34: 56: 78: 01.
    In a step ESU3, the central control unit U determines whether the temperature state variable P1S1D1 has a correspondence in the Bluetooth profile of the virtual device and the possible conversion function. In the example considered, the temperature state variable in degrees Kelvin of the domotic device DI can be mapped to a notification attached to the state variable P2S1D1 or characteristic "Temperature" of the "Environmental Sensing" service emulated according to the second protocol of P2 communication. The central control unit U applies the following conversion function which corresponds to a conversion in degrees Celsius and an integer value with an accuracy of 0.01: T-> floor ((T-273.15) * 100). The central control unit U then sends a P2MS supervision message in the form of a Bluetooth notification to the connected node NI with the new temperature value P2S1D1.
    According to a variant using the control method, an active reading of the temperature can be performed.
    In this case, the NI node which is a paired Bluetooth client with the virtual device sends a Read Request for the state variable or "Temperature" characteristic of the "Environmental Sensing" service of the virtual device, in a step ESN15. The central control unit can respond by using the last value received from the sensor 10 or send a command to the device to obtain this value which is stored by the central control unit U.
    Example 2
    A second example relates to a domotic device DI of the dimming lamp type according to a first local communication protocol PI type ZWave intended to be published as a resource type "dimmer.lamp" in a second target protocol P2 type OlC / lotivity on an R2 network of IP type.
    During the process of configuring or pairing the sensor 10-homecontrol with the central control unit U, in the configuration message MCfD1, the home automation device D is described as a device of the "Light Dimmer" type with a location identifier P1D1A corresponding to the address ZWave 26 which has a definition of a function group ("functional cluster") "SWITCH_MULTILEVEL_V3" corresponding to a setting of an intensity level. The central control unit U registers with the home automation device to receive a status change notification or a state variable describing the operating state ("report"). The central control unit U determines a type of device or profile according to the second target protocol P2 lotivity to be used to publish this device using a correspondence table. In particular, the profile or type of corresponding resource identified is "oic.r.light.dimming" having a proportional lighting control value between 0 and 100%. The central control unit then determines a location identifier P2D1A according to the second communication protocol. The second target communication protocol P2 does not necessarily require a different network address per device. Thus, it is possible to use a single network address, for example the IP address of the home automation controller (eg 192.168.0.2).
    To construct the location identifier of the virtual device, that is to say in this case a URL according to the second target protocol lotivity, the central control unit U selects a resource number that does not still assigned by this central control unit U starting from 1 then combines this element with the IP address to obtain for example the following URL: oc: //192.168.0.2: 1234 / light / l. The central control unit U proceeds in a step ECfU7 / ECfU8 to the recording of the correspondence of the type of device according to the first and the second protocol P2 and the correspondence of addresses according to the first and the second protocol in a table. some knots. The central control unit U also records or declares the resource in the lotivity server software it executes, the software being active listening on the address 192.168.0.2 port 1234.
    The discovery process can then be implemented.
    The declared virtual DI device may be discovered by a standard lotivity client executed by an NI node using a multicast discovery request that corresponds to an MD discovery message.
    The supervision or control method can then be implemented.
    In the context of a control method, a lotivity client or NI node having discovered the virtual DI domotic device can then control the DI device by sending a P2MC command message in the form of a "CoAP PUT" request concerning the property " dimmingSetting "of the resource identified by the location identifier P2D1A according to the second communication protocol P2" oc: //192.168.0.2: 1234 / light / l ".
    In this case the lotivity server of the central control unit U receives the control message P2MC and then determines the location identifier P1D1A according to the first corresponding communication protocol PI, in the example considered "ZWave 26" using the table some knots. The central control unit also determines the conversion function of the command or function (lotivity -> ZWave) and then constructs and sends a P1MC control message in ZWave format to the home automation device D1. The central unit can then, as a function of the response P1RC of the domotic device D1 to the command, respond to the control message P2MC by a command return message P2RC corresponding to a success or failure of the command or the command. function call.
    According to an example of the supervision method, the node NI can consult the value of a current state variable of the domotic device D1 by sending a command message P2MC in the form of a "CoAP GET" request concerning the resource identified by the P2D1A location identifier according to the second P2 communication protocol "oc: //192.168.0.2: 1234 / light / l".
    In this case the lotivity server of the central control unit U receives the control message P2MC and then determines the location identifier P1D1A according to the first corresponding communication protocol PI, in the example considered "ZWave 26" using the table some knots.
    Subsequently, the central control unit U determines the state variable (s) P1S1D1, P1S2D1 according to the first local communication protocol PI ZWave to be returned, for example the last value received from the "cluster SWITCH_MULTILEVEL_V3" and the conversion functions. possible, and in particular the name of the state variable in the second lotivity target communication protocol, namely in the present example the "dimmerSetting" property. The central control unit U can then convert the value with the conversion function and respond to the query CoAP with the value obtained.
