IoTaWatt integration reporting incorrect values

[tomlut]

The problem

My solar inverter is only capable of outputting 6kW so imagine my surprise to see the core Home Assistant IoTaWatt integration reporting it producing 6.7kW:

The IoTaWatt itself never recorded a value this high:

That's interesting. I don't know how this could happen - iotawatt component just uses the REST api to talk to the iotawatt device, and stores what it gets. Can you try zooming in on iotawatt graph, see if there was a spike around then? Maybe some interference?

Mine seem to align pretty well

[tomlut]

That's as close as I can zoom in. I can't zoom in any closer than a +/-5 minute period in the history panel.

Also as it it past the 7 days I store in the recorder I only have 1 hour mean LTS data now.

@tomlut Is your solar_prod a direct measurement, or is it an output with a formula etc? Other than that - I have no idea: HA just uses the values directly from the REST interface to iotawatt.

[tomlut]

It is an IoTawatt integrator output.

Just noticed it happened again a couple of days ago:
