Viessmann Heatpump consumption (API)

← PV, Battery, Grid, Meter

This page shows the nightly version. There is no release version yet.

Reads the heat pump's current electrical power consumption (heating.power.consumption.current) as an additional consumer (aux). The heat pump then appears under "Consumption" in the energy flow and its usage feeds the evcc statistics - independent of whether evcc controls the heat pump.

Usage areas

• Smart consumer
