    I intend to install bistable relays for lighting for the whole house.
    I would like to have a hotel function - one switch to turn off all the lights. FF has a hotel one, but it costs 2.5x as much as a regular one. There will be some of this so hence my question - how to separate the main switch from the room ones.

    If there is a control panel then this can be integrated with it.
    If there is not, then additional relays that will cut off the power supplied through this switch.

    With relays OK, but you have to duplicate each bistable with a relay.
    And do you know what is inside the SEP-01 separator from F&F?

    As the power supply/control of DC relays, a simple diode will suffice ( well maybe a whole sea of them ;) )

    It is simpler and cheaper to lead the circuits you want to control centrally out to the switchgear cy , and insert a reversing contactor there and control an ordinary switch. Bistable relays go inactive when cut off and voltage is applied, at least those from f&f.

    Also right. I somehow can't get away from thinking in alarm fashion and the possibility of also turning on some of the lights e.g. during an alarm ;) immediately crosses my mind.

    Here is the solution

    It would be nice to have such an option, but if the simplicity of the solution is not there then just turning off all the lights would be OK too.

    There are plenty of solutions, you are only limited by the stage of wiring you are at, and your imagination and wallet :)

    Ah the affluence of the wallet. :-) . However, I guess the bistable hotel ones will be the best option, although I need to consider whether to stop at the collective shutdown function with the main reversing contactor. Thank you for your suggestions.

Topic summary

The discussion addresses wiring bistable relays for whole-house lighting with a hotel function, enabling a central all-off switch. The main challenge is separating the central switch from individual room switches cost-effectively, as dedicated hotel-function bistable relays (e.g., from F&F) are significantly more expensive. Suggested solutions include integrating the central switch with an existing control panel or using additional relays to interrupt power supply centrally. One approach involves duplicating each bistable relay with an auxiliary relay or employing a reversing contactor controlled by the central switch to manage circuits collectively. Diodes may be used for DC relay control to prevent interference. Bistable relays from F&F deactivate when power is cut and restored, influencing control strategies. The choice between using specialized hotel-function bistable relays or a collective shutdown via a main reversing contactor depends on budget and wiring stage. The SEP-01 separator from F&F is mentioned as a component of interest for separation purposes.
