 Air quality state can be `UNKNOWN`, `EXCELLENT`, `GOOD`, `FAIR`, `INFERIOR` or `POOR`. To use different values, specify them in **airQualityValues** in that order.
 
-For Air Quality History (in the Eve-App) you have to use `getAirQualityPPM`.
+For Air Quality History (in the Eve-App) you have to use `getVOCDensity` (Eve Room 2) or `getAirQualityPPM` (Eve Room 1).
+
+History records need to be cleared when Migrating from Room 1 to Room 2 because they are not compatible.
