Hey all,
I do have four of those ZigBee door sensors available from Lidl. Two of them work flawlessly, but two will stop sending state changes after a couple of hours or days. I’ve re-paired them several times, or used “reconfigure device” in ZHA, to no avail - eventually, they’ll stop transmitting state changes again.
The devices do not vanish from HA, however. “last seen” is updated regularly, LQI is 255. When the sensor is opened/closed, the device’s LED does even flash. Also, the debug log shows nothing when the sensor is opened or closed.
Are some of these sensors just broken?
