FAQ: Philips Hue and Other Smart Bulbs - What sort of light switches to use with them? (Long FAQ) Wiki
Thinking on a big move to Hue lights, the real question is - what switches to use with them? If they’re all automatable via ST and other devices, do I really want to put them all on controllable switches too? There’s the advantage that I can arrange to ensure those switches are on so that the the Hue bulbs would be too…but it also leaves open the ability for folks to just turn them off and leave them off. Hmm. Thoughts?
