alt Hacker NewsThey missed that IKEA has just released a new smart home suite including a motion/light sensor for $9.99 [1]. Full thread/matter support and some also have zigbee to maintain backwards compatibility to legacy IKEA stuff.
I’m migrating from my zigbee stuff bridged through home assistant to HomeKit. Now I have thread to HomeKit directly

I get that it is a cheaper solution, but how pleased are you with responsiveness and reliability of the IKEA stuff?
Keep in mind that often motion sensing isn't what someone wants... great for hallways, doorways, and transitional space where someone is expected to be moving, but not great if you're going to be sitting for a bit. Presence sensing is a little more expensive but has gotten a lot better (millimeter wave stuff), great for something like a bathroom or kitchen where you might be sitting for a while but still want the lights on.
Aliexpress also sells bunch of no-name Zigbee motion sensors, proximity sensors to detect if door/window or whatever is open, which work with Home Assistant through Zigbee2Mqtt. I tried some with good reviews and found them to work allright.
