I recently bought a Zigbee motion sensor, and it paired fine with ZHA in Home Assistant. You can find the product here: Zigbee Motion Sensor.
I paid $28 AUD for it, but I’ve found much cheaper ones on AliExpress. Here’s a link to a cheaper alternative: Cheaper Zigbee Motion Sensor. Tho its super cheap… it seems the same model but i can’t gaurantee its the same as i got.
Hope this helps anyone looking for budget-friendly Zigbee motion sensors!
BUT… If you were doing an escape room, and you put people into a completely dark room with 20 of these things red lights popping on when you move, now that would be good…
Put them up in pairs…
