I would like to use WALLC-S to only allow switching OFF a binarySwitch, i. e. not allowing to switch it ON. I also would like to do it in such a way, that is also works, when the RaZberry is down. So I thought the way to go would be associations. Unfortunately the binarySwitch is quite dumb; it does not support SwitchAll.
Is there a way to directly associate the WALLC-S with the binarySwitch and only allow switching OFF (even when the RaZberry is not available)?
