Embodiment Construction

[0031] exist figure 1 In the home automation installation INST represented, the various elements SRU, MMI, SBU, ACT1, ACT2, ACT3 communicate on the same radio frequency network RFN marked by double lines. Communication between elements is performed by a bidirectional transceiver RX / TX distinguished by an address or identifier of each element. The installation comprises elements ACT1, ACT3 powered by the grid EPN, while other elements SRU, MMI, ACT2 are powered themselves. Communication between elements of the network may be ensured by other means, such as in particular infrared transmission means. All components use the same communication protocol.

[0032] The self-powered sensor or sensor unit SRU whose address is represented by the SRU converts the value of the climate or comfort parameter into a digital quantity and / or a control command established on the basis of a comparison threshold.

[0033] The Man-Machine Interface MMI Rack, whose address is represented by MMI, e...

Abstract

The method involves receiving and recording information, sent by a sending element, using a substitution element (SBU) for the attention of a receiving element when the receiving element is in a sleep mode. The information is sent between the sending element and the receiving element using the substitution element for the attention of the receiving element when the receiving element is no longer in sleep mode.

Description

technical field [0001] The invention relates to the transmission of commands or data between elements of a home automation installation for waking up self-powered elements. Said elements communicate reciprocally, for example by radio frequency, and in particular they may comprise actuators, sensors and control points. [0002] The actuators are usually powered on the commercial grid, while the sensors and control points are usually self-powered, for example by dry cells or rechargeable batteries. [0003] As soon as self-powered elements are of the bidirectional type, a problem arises in such installations: how to avoid persistent listening of radio frequency receivers, which results in increased power consumption and thus reduced autonomy. [0004] This problem has been addressed in many inventions. Background technique [0005] In a first group of inventions, patent application WO 00 / 28776 discloses receivers that wake up at fixed times. Therefore, they need to contain ...
