Differential pressure measurement cluster

This cluster provides attributes and commands for configuring the measurement of differential pressure, and for reporting differential pressure measurements.

Differential pressure values are given in Pascal (Pa).

Periods other than time intervals used with Configuration reporting commands are given in millisecond (ms).

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 attribute


The Measured value attribute contains the last measured differential pressure value.
