    The first subsystem I'm working on is the light control.

    It is possible to have two cases:
    1) more than one control per light point
    2) a single control for light point

    To ensure that it is possible to drive the light from any switch the node must behave as a 4 way switch.

    The first case is the simplest, it is sufficient to connect the node in series to the switches [1].

    The second case is slightly more tricky, it is necessary to replace the single switch with a 2-way switch and put it in series with the node [2a], or with a push-button connected directly to the node [2b].

    The "SWITCH NODE" must have three functions:
    - switch ON/OFF the load
    - sense if the load is ON or OFF
    - communicate to receive commands and send the status of the load
