Reconnect Aqara Temperature and Humidity Sensor

I have a couple of Aqara Temperature and Humidity Sensors in my house. Occasionally some of them disconnect for some reason. I have up until now only been able to reconnect by basically holding the reset button and resetting the device. It is a bit annoying to do this on some of the more harder to reach sensors in the attic and what not.

Is it somehow possible to reset them without using the physical button?

Did you work anything out here? I have the same problem…

Use quality batteries and improve the zigbee network with AC powered devices seems to reduce the nbr of disconnects.

Same problem here. On 3 occasions I was never able to reconnect the sensor, so I had to bin them. Very annoying. And expensive.

I also posted this in another thread but will repost on this as well.

I run into this periodically - the answer seems to be to go into the coordinator and completely re-add the device after changing batteries. After you add new device in the coordinator just hold the button on the sensor for 5 seconds till it blinks 3 times. The name will probably still be there - you may need to add an area or label again but my automations survive re-adding the sensor to the coordinator.

The problem seems to be a defective implementation of the Zigbee 3.0 protocol. The Aqara temperature sensors connect to some nearby router, but if they don’t like it, the will just update once and go to sleep forever, at least in my case.

This thread contains a workaround to awake the device: Aqara temperature sensor disconnects - #8 by SuperJMN

(For those wondering, it’s about installing the ZHA Toolkit (requires HACS and adding a line in config.yaml to load the integration).

Very annoying, but maybe it leads to a better fix.
