Overview

Temperature Measurement Cluster (0x0402)

Provides an interface to temperature measurement functionality, including configuration and provision of notifications of temperature measurements.

Temperature values are expressed in hundredths of degrees Celsius (0.01°C). For example, 2550 represents 25.50°C.
