We have a maintenance sensor (s/n 0013A200-41C35B99) that is online for ± 6 months which last week suddenly went unresponsive. We see that the battery power the last 2 days before going down went to 2.8V and then abrupt stopped.
Placing new batteries in did not solve the issue. Also factory reset etc is not helping.
In the config GUI the sensor is not appearing while other do show .
Are there any diagnostics that can be done?
