Are you looking for a system that is strictly motion sensors, or do you have a smart assistant that supports other wireless protocols than Wifi?
My strategy as a home assistant user has been to lean on smart switches and dumb bulbs to the extent that I can, so that I can locally control fixtures without having to rely on the assistant being awake and healthy. I do have a few instances where I have dumb switches and smart bulbs, but only where I also want to control the light colors and where the bulb is controlled right at the fixture.
That said, there does appear to be a tasmota 3-pole switch by Martin Jerry on Amazon. You'd probably just replace one of your 3-pole switches with the Tasmota and leave the other switch alone. You could pick up one of the Everything Smarthome presence kits and use that for your motion sensor.
Hope any of this helps!
As someone on semaglutide therapy, I can share that a large calorie deficit hits you in the wills to live. At some point even just eating feels like a stop at the gas station to fuel up, and it hardly matters whether it's 87 or 95 octane. Hell, rancid fry oil would even work. At some point, you stop caring whether you eat because it feels like another chore.
Eventually your metabolism syncs up again with your energy demand and you start getting interested in food, except you're way more selective about how you're (edit: ~~spending~~) acquiring those calories. I almost can't abide by junk food, fast food, or breaded fried crap anymore. But neither do I want salad or vegetables because they're "fluffy." Too much volume, not enough calories. I want about 6 or 10 forks full of food, and then that's it. And it'd best taste good, or I can't be bothered. Restaurants easily stop looking like a good deal.
Anyway that's a digest of my diary for the last 22 months. Do with the info as you will.
