Hi alextingle,
Users can choose a 4 day or 28 day calibration configuration, but the calibration time does not support automatic switching. Please refer to the configuration description on the integration document:
The reference value for calibration completion is 4 days or 28 days, not 30 minutes. You need to refer to the value of accuracy, and the IAQ value is most accurate when it reaches 3.
Before resetting, only the state needs to be saved, no timestamp needs to be saved.
