energy meter goes negative every day

Anybody knows why this happens? Happens every day when energy dashboard is updating.

After two days of “misbehaviour” it’s back to normal. So one day it went negative and the other - positive (not the exact amount) and now for two days it’s ok while no updates or changes where done. If it occurs once again, I’ll try as you, @bramstroker , suggest and will post the results. Thanks for a fast answer

Not sure about this, nothing really changed in the calculation / logic etc in latest versions.

Your problem is the individual energy sensors misbehaving somehow, so you should first focus on investigating that further. The powercalc group logic just sums all the kWh from individual entities. So when 3 entities add 0.9 kWh the group will also increase by 2.7. Could you try creating a second energy sensor for virsus desine power using built-in HA helper Rieman sum (Devices & Entities -> Helpers)? Powercalc creates similar sensor under the hood and uses all the logic from HA. When this second energy sensor created with HA helpers is behaving exactly the same the bug is in HA codebase, and we should submit a bug upstream in homeassistant core repository.

When the HA helper one is correctly calculating and the one with powercalc not then we can further investigate.

What do you mean with the configuation “show nothing”? That’s expected behaviour when this is a light profile from built-in library. You can only alter some settings, but the power values itself are dynamically calculated from the known measurements from the library.
