Perhaps combine with a motion sensor to see if the lights should be on at all. Then the microphone only switches between modes.
This made me wonder, are there any mechanical switches that can be switched by a smart something? As in, a regular switch where the user always has mechanical control, even when the smart system is down, but that optionally can be switched by a smart sytem, state reading is optional.
