Relative Humidity Measurements Cluster

 

This cluster delivers the relative humidity of the remote sensor, and the minimum and the maximum values that it is capable to measure.

If a field of the payload starts with 0x, this means that it’s an hexadecimal representation, and if it starts with 0b, it is a binary representation.

Any multi-byte numerical value is serialized in “Big Endian” order.

Measured Value


The Measured value information attribute set contains  the attribute representing the humidity of the device.
