Your Z-Wave Temperature, Humidity, and Motion sensor and Air Quality sensor can precisely measure the humidity within the wiring device. Accuracy is achieved through application of a humidity offset to account for variability of the installation environment.
Humidity Offset
Parameter: 144 (0x0090)
Size: 1
Range: -100 to +100
Units: Percent
Comments: Value applied to humidity sensor readings to compensate for fixed ambient temperature variations due to installation variability. Can be used to improve accuracy when compared to a calibrated external relative humidity measurement source.
