Unfortunately even when you add a router, it doesn’t necessarily means that particular device will route over it, mostly Aqara devices misbehaves in this. On the other side, more routers is always better to create stable mesh. When you recreated your Zigbee mesh, you followed simple rule - first routers, battery powered devices second, right ? (even if you mesh has been stable so far and you did not more devices since July, I don’t believe it would have been necessary)
Jul 22 Athom released final v12 - do you use as well experimental versions or it’s possible that around that date you have installed v12 ? I see some issues since that version as well, randomly disappearing devices from mesh, almost have to do repair every week while it was stable for a year for me.
I suspect this change :
**Zigbee**
* Fixes an issue that caused unnecessary communication with devices.
But it’s just my observation, which could be wrong.
