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.

I use Aqara motion sensors. They are cheap (Ali express), battery operated (can put them anywhere) and have always worked for me.

They are ZigBee, so the caveat is that you will need a dongle to use them. Mine is a Zig Ah Zig Ah from ElectroLlama and cosy under £20.

The reason I moved from WIFI to ZigBee is for reliability. WiFi just isn’t reliable. Any mains powered ZigBee device (bulbs, switches) are also usually routers, so the signal can be bunny hopped between nodes in the ZigBee network, unlike WiFi.

Also yes, one of the beautiful things about HA is that it is the middle man between many many different manufacturers of smart home appliances, so if you automate your main lights you should be able to add in a plugged in lamp to the automation.

I can’t speak to the Feit brand so you’ll have to look how to control those, so the home assistant forums are your best bet for integrating those. Wemo brand does have an integration, so it should not be too hard to use those. As far as presence detection, these athom sensors have worked well for me, however I have not used them in bedroom where people are in bed sleeping.

Yes home assistant allows you to take actions based on the state of other smart devices. For example, when I turn on my foyer light, that also trigger my hallway lights to turn on.

I have never used Feit lights with Home Assistant, but yes, my bedroom lights turn on when it senses motion. That automation disables when my living room lights are off (assuming we turn them off at bedtime) or when my phone plugs in to charge (which I do at bedtime). I use a motion sensor by Phillips Hue, and it integrates directly with the Home Assistant Yellow thru its Zigbee radio without an additional hub.
