W200 thermostat loosing synch with Apple Home

I have had some aqara devices move to a different room in AppleHome. They stay in the right room in the Aqara app. And, they look fine there. In both cases it has been a sensor (FP300 and contact sensor). Other sensors were fine. This has happened twice. Once when the internet went down for a few minutes. The other time was when I changed an Apple border router. The worst part of the problem was that I lost the automations associated with these sensors. What could cause this?

@dsmith_ds1954 Room “drift” in Apple Home (while everything still looks correct in Aqara Home) often points to the HomeKit side temporarily losing its normal link to the hub/border-router path—especially since you noticed it right after a brief internet outage and after swapping an Apple border router.

A key thing to check is whether your Aqara hub/camera and your Apple Home Hub (Apple TV/HomePod) are consistently staying on the same LAN. HomeKit responsiveness and state sync rely on both being on the same local network; if that relationship changes (router swap, network segmentation, different SSID/VLAN, etc.), you can see odd Home behaviors like “No Response” or inconsistent metadata syncing【This information comes from community discussions and user experience summaries and may vary by environment.

If it keeps happening, the usual “clean-up” step on the HomeKit side is to remove the affected accessory from Apple Home and add it back by scanning the HomeKit code again (this can reset HomeKit’s cached info for the accessory)【This information comes from community discussions and user experience summaries and may vary by environment.

If you want, share what your Apple Home Hub is (Apple TV vs HomePod), whether you run multiple SSIDs/VLANs, and whether the Aqara hub is on 2.4 GHz while your Home Hub is wired/5 GHz—those details can help narrow down why the LAN relationship changes after network events.

I had this issues when I first added my device. When I restarted my router and hub, I stop having the disconnection

I see the same thing with my FP300s but usually only after the M3 hub they are connected through rebinds to the matter server. Everything all good in Aqara home app, but I see the devices in HA have rebound (either duplicated entity id’s but with _1 after the entity name). The new entities are live and old entities are unavailable which breaks automations to your point.

Do you have your devices going into Home Assistant or just using AppleHome? HA has a great service called Watchman which I have running on a schedule to check for unavailable entities and scripts with entity id errors.
