I have all my houses completely smart outfitted. Except the bedrooms. Yes you can have a wireless switch control a wireless light. I do that everywhere because then nobody gets confused and flips a switch.

I haven't touched a light switch in years. Every room has mmWave sensors either in the ceiling or on a shelf or both. You walk in, lights go on. Leave the room for a minute, lights go off.

The problem is a bedroom where that doesn't work. When are lights on? When you're in the room and not in bed? Ok. That's a lot more complicated. Get up in the middle of the night to pee, now the whole room is blasting light and waking up your partner. Reach for your phone, detected as motion outside the bed, inter of a tip lights come on. It never seems to work because too many variations.

Because of that I keep a remote by the bed. The light switch works, the phone apps work, the voice assistants work, all as usual just no automatic sensor. Then in addition the remote by the bed can turn the lights on full, one bulb dim, or off. One for each side.
