Is local "pm02Compensated" same as cloud "pm02_corrected"?

Is the “pm02Compensated” value obtained through the local API the same as the “pm02_corrected” obtained through the cloud-based API?

And are one (or both) of these the EPA calibrated readings? In Advanced Settings, I’ve set the calibration formula for my specific PMS5003 sensor (PMS5003_20250116) and the box for “Apply EPA Formula” is checked.

I’ve got a Model: I-9PSL-DE running firmware 3.4.1

Hi @srroof,

Yes pm02Compensated from the local API and pm02_corrected from the cloud API should represent the same value. I’ll flag the naming mismatch to the team.

The corrected/compensated value you see in both APIs is after both the batch correction and the EPA correction as you’ve enabled both in the dashboard.
