About

DeWarmte is a Home Assistant integration for monitoring and controlling DeWarmte heat pump systems. It supports four devices: Pomp AO, Pomp MP, Pomp T and Heatcycle, and connects through the vendor's cloud with the MyDeWarmte account email and password. It adds sensors for values such as water flow, supply and outdoor temperature, heat output and electricity consumption, along with binary sensors, a climate entity, numbers, selects and switches. The switches cover options such as forced heat pump only, forced backup only, silent mode and several backup modes. Two actions start and stop a forced cooling run for a fixed duration. Energy sensors and a simple coefficient of performance sensor are derived from the power readings, and the update interval can be changed in the options. Setup is done in the UI, and schedules are not yet supported.
