Process of communication between a first node and a second node of a home automation installation

A first communication node of a home-automation installation comprising a processing unit and non-transitory memory storing program instructions, wherein the first communication node is programmed to execute a method of communication between the first communication node, a second communication node, and a third communication node of the home-automation installation using a processor, the method comprising:

• transmission of a first information message from a first transmitting part of the first communication node to a second receiving part of the second communication node,
• following reception of the first information message by the second communication node, transmission of a confirmation signal from a second transmitting part of the second communication node to a first receiving part of the first communication node, the confirmation signal comprising a signal confirming to the first communication node that the first information message has indeed been received and understood,
• maintaining the first receiving part in the active state so as to be ready to receive a transmission of a second information message if the confirmation signal received by the first communication node contains a conversation continuation indicator signaling to the first communication node that the second information message has yet to be received and placing the first receiving part in the inactive state otherwise,
• if the confirmation signal received by the first communication node contains the conversation continuation indicator, transmission of the second information message from the second transmitting part of the second communication node to the first receiving part of the first communication node following transmission of the confirmation signal, wherein the second information message comprises a signal informing the first node that the third communication node wishes to establish contact with the first communication node,
• following reception of the second information message by the first communication node, the first receiving part is set to remain in the active state so as to be ready to receive a third information message comprising information to establish contact with the third communication node.

A home-automation installation comprising at least one first communication node, at least one second communication node, and at least one third communication node, wherein the at least one first communication node is adapted to transmit a first information message from a first transmitting part to a second receiving part of the at least one second communication node, and wherein the at least one second communication node is adapted to transmit a confirmation signal from a second transmitting part to a first receiving part of the at least one first communication node upon reception of the first information message, the confirmation signal comprising a signal confirming to the first communication node that the first information message has been received and understood, further wherein the first receiving part is maintained in the active state so as to be ready to receive a transmission of a second information message if the confirmation signal received by the at least one first communication node contains a conversation continuation indicator signaling to the first communication node that the second information message has yet to be received and placed in the inactive state otherwise, further wherein, if the confirmation signal received by the first communication node contains the conversation continuation indicator, transmission of the second information message from the second transmitting part of the second communication node to the first receiving part of the first communication node following transmission of the confirmation signal, wherein the second information message comprises a signal informing the first communication node that the third communication node wishes to establish contact with the first communication node, and, following reception of the second information message by the first communication node, the first receiving part is set to remain in the active state so as to be ready to receive a third information message comprising information to establish contact with the third communication node.
