Hi.
Have a self made integration for my StecaGrid solar power inverter.
I have then added a Riemann sensor for summarizing the energy it produces.
That went well for a period of time, but lately I get this error:
2024-03-11 16:22:13.606 ERROR (MainThread) [homeassistant.helpers.event] Error while dispatching event for sensor.stecagrid_power to <Job track state_changed event ['sensor.stecagrid_power'] HassJobType.Callback <function IntegrationSensor.async_added_to_hass.<locals>.calc_integration at 0x7f3acc2e5a80>>

raise ValueError(
ValueError: Sensor sensor.stecagrid_power_total has device class 'energy', state class 'total' unit 'kWh' and suggested precision 'None' thus indicating it has a numeric value; however, it has the non-finite value: 'NaN'
In my energy dashboard I don’t get any date for my solar panel because of that.
I just can’t get my head around what suddently is wrong
