I don't have any Aqara motion sensors. I do have two Ikea ones though and they work fine.

One is in my home office to turn the lights on and off, it works fine and I've never had problems with it not detecting me. It's not instant, but always responds within a second or two.

The other one is sitting by the cat litter boxes and is used to trigger an automation involving an air cleaner. It senses the cats at a range of about 1.5m just fine.

The next thing I'm interested in is the crop of mmWave presence sensors. There are a lot out there and I'm not sure if there's a clear winner in this space yet.
