Daikin EKRHH Modbus
Plug-inRead and control a heat pump over local Modbus
This integration connects Daikin heat pumps to Home Assistant, a home automation hub, through local Modbus TCP. It exposes supported temperatures, energy readings, setpoints and operating controls without polling Daikin’s cloud.
Altherma 3 and supported air-to-air units need the EKRHH HomeHub set to use case 3 or 4. Direct Altherma 4 support is experimental; despite the README’s broad RTU/TLS wording, the inspected implementation creates an unencrypted TCP client.
- Control your Daikin without Daikin's cloud
