HomeAssistant addon wrong PM values when Airgradient dashboard is OK

Following up on this, noticed a few times where the API pm02/pm02Standard were non-zero, and the Display continues to (correctly) use the pm02Compensated now (with the “corrections”) so I’m considering the issue resolved for me (thanks again for all the help on this thread!):
