I have no idea how to reliably sense who or how many people are in a room, going by questions here. The presence sensors I’ve tried so far are really inadequate
even if I knew who or how many are in the room, I have no idea if there is any logic to correctly decide whether I want the light on and how much
voice control of lights is more useful to me, although Alexa is slow and I haven’t yet tried other approaches
scheduled lighting has been surprisingly useful. That reminds me, I need to schedule dining room at 20% at 6am m,w,f
