I booted up my old instance and checked the energy and power readings in grafana and collected some information.
I have three devices;
- device 1:
first reported value: 2021-10-20 17:19
last reported value: 2022-02-03 06:04:00
- device 2:
first reported value: 2022-01-14 17:45
last reported value: 2022-02-03 06:10:54
- device 3:
first reported value: 2022-01-14 18:14
last reported value: 2022-02-03 06:15:08
The ‘last reported value’ is the last sample where the value (energy or power) changed. After that there are still samples in influx-db, but the line is flat.
After adding one of the devices in my new HA instance it just says
None on both energy and power entities.
In zigbee2mqtt it says
So all three devices stop working at nearly the same time regardless of when they were added and I wonder if anyone else had their device stop working at that date.
I didn’t notice them not working until some time later, so I could not know if something happened at that time, e.g. zigbee2mqtt update. But I don’t think I would have done any maintenance that early in the morning.
