Repository for Home Assistant HACS integration for Dimplex heatpumps via modbus
Local integration for Dimplex heat pumps equipped with the NWPM Touch network extension or a System M heat pump. The gateway (a Carel pCOWeb board) runs a local Mosquitto MQTT broker and, optionally, a Modbus TCP server; this integration talks to both and does not depend on the Dimplex cloud.
Control your Dimplex NWPM via Home Assistant using the modbus interface.
