Random Low Battery Alerts

[Dave21w]

Anybody else getting these, not happening on all devices but driving me nuts with random alerts.

With what Zigbee integration do you see this?

[Dave21w]

Running zigbe2mqtt with the auto discovery option, current stable Domoticz on Pi3B+ O/S is Buster
Sorry I missed your reply otherwise I would have responded sooner.

Thanks

If Zigbee2MQTT is sending those incorrect values there is not a lot Domoticz can do. With MQTT Explorer you should be able to see what values are send by Zigbee2MQTT. Perhaps it is already a known issue in Zigbee2MQTT?

Could not you set your alerts on 2,8 Volts or lower?
Or better set it on a battery percentage?

Could it be that your sensor is a Xiaomi GZCGQ01LM light intensity sensor?
I have 3 of them, and all of them have the same behaviour. Almost every day the battery level drops to 0, causing Domoticz to report a low battery level.
The battery level of these devices in zigbee2mqtt is not reliable as it jumps up and down. I just ignore it.

Hi @claude2666
Sorry I missed your reply from a while back, yes indeed mine are the Xiaomi GZCGQ01LM light intensity sensors, I have 2 off them and they both perform the same, what would be good would be if you could set Domoticz so that the battery had to be below a set point at least 3 times in a certain period before getting an alert. None of my other Xiaomi devices have this problem, in fact my door and window sensors seem to go forever on one battery!
