Overview

Relative Humidity Measurement Cluster (0x0405)

Provides an interface to water content measurement functionality. The measurement is reportable and may be configured for reporting.

Humidity values are expressed in hundredths of percent (0.01%). For example, 5500 represents 55.00% relative humidity.

Specification: Matter 1.4 § 2.6
