Compatibility summary
Aqara U200 is a reasonable Apple Home candidate if the buyer is specifically looking for a retrofit smart lock with Matter over Thread and Apple Home Key support. Aqara product and manual materials identify the U200 as Matter over Thread and describe Apple Home or Home Key setup. The CSA product listing separately identifies Smart Lock U200 as a Matter-certified device with Thread and Bluetooth transport. The important caveat is setup: Apple Matter and Thread guidance says Thread-based accessories need a Thread-enabled home hub or a compatible Thread-capable iPhone path, and real behavior can still depend on firmware, region, door hardware, and which Apple hub is present. Treat this as conditionally supported rather than universally plug-and-play.
