BDRthermostatHA

BDR (Baxi, De Dietrich, Remeha) thermostat custom integration for Home Assistant

This component provides custom integration with BDR Thermea branded thermostats. It was tested with Smart TC app and De Dietrich devices. It does not work (or only limited functionalities) with Remeha eTwist App due to API differences.

How to install

You can use HACS to install this integration as custom repository

If you are not using HACS, you must copy bdr_thermostat into your custom_components folder on HA

Configuration

Configuration via integration is recommended. Add an instance of BDR Thermostat using the UI:

And follow the steps:

Pairing code can be get from the thermostat device or from the Smart TC app.

Screenshot

Integration will create a climate entity and several sensor entities. It will look like this in Lovelace dashboard:

I used following YAML code for the dashboard card:

square: false
columns: 1
type: grid
cards:
  - cards:
      - entity: climate.bdr_thermostat
        type: thermostat
        name: Termostat
      - type: entities
        entities:
          - entity: sensor.bdr_thermostat_outside_temperature
            name: Venkovní teplota
          - entity: sensor.bdr_thermostat_status
            name: Stav
          - entity: sensor.bdr_thermostat_water_pressure
            name: Tlak vody
          - entity: sensor.bdr_thermostat_water_temperature
            name: Teplota vody
          - entity: sensor.bdr_thermostat_errors
