AirNow - "The unit of sensor.airnow_aqi (None) cannot be converted to the unit of previously compiled statistics (aqi)"

[ziptbm]

The problem

I'm seeing this error with each reboot related to the AirNow AQI Sensor. Do I just need to delete all old statistic data or will this change back?

Within the Developer Stastics Menu, I get this option:

Selecting the first option does nothing apparently, so that's why I'm filing this here.

FWIW, I'm seeing the exact same problem.

[asymworks]

The AirNow side of this is due to the change-over to use the new Device Classes in #94986. The SensorDeviceClass.AQI corresponds to a None unit of measurement, while my original code used aqi as the unit of measurement, which seems to be deprecated now.

I think using the dialog to change the historical units from aqi to ` (i.e.None`) is the right way to fix this and get statistics working again, but if that isn't working, that is probably a separate bug unrelated to the AirNow integration.
