KNX active power values are typically transmitted in watts using DPT 14.056.

DPT 14.056 (Power in W) is a 4-byte IEEE-754 float and is the standardised datapoint for instantaneous active power on KNX. The float range easily covers everything from a domestic socket reading a few watts up to industrial feeders in the megawatt range. Using a standard DPT instead of a custom scaling guarantees that every visualisation, logger or load-shedding logic interprets the value correctly.

Do not confuse DPT 14.056 (W) with DPT 9.024 (kW) - the underlying encodings differ and a wrong import multiplies the displayed power by 1000.
