Hi everybody,
I’m currently using Home Assistant 2025.4.3 on my Raspberry 5 with the Sonoff Zigbee-Dongle and Zigbee2MQTT.
From one day to another my energy dashboard displayed some crazy high values for 3 of my smart plugs.
All smart plugs are the same brand and model, only 3 of them seem to display incorrect values.
As a result 3 devices show up in the energy Dashboard with very high energy values like 31,83 Kwh in just 1 hour, which is impossible.
(I would add a picture but I’m new around here, so I’m only allowed to use 1 picture)
The total energy consumption also seems to be incorrect as a result, it shows 356 kwh in just 24hours.
I noticed that the devices themselves seem to have the correct values, at least the value “total energy” seems to be ok. But I also noticed a very strange behaviour by looking at the displayed graph.
The values seem to “flicker” and I’m pretty sure this is the cause of my issues.
All of the 3 “faulty” smart plugs show this kind of problem.
The other 7 smart plugs are fine and showing a steady and continuously ascending graph.
Zigbee2MQTT itself also shows the correct total values.
I tried reconnecting the devices in Zigbee2MQTT, but this didn’t fix the issue.
I can’t find an issue in the devevopler tools aswell.
Also all the smart plugs should be configured the same.
Can this type of issue be caused by an unavaiability of the device/sensor?
How can I prevent this problem in the future?
Thanks in advance!
