[!IMPORTANT] This integration will not work anymore after March 11th 2024 due to changes made by Daikin (see https://github.com/speleolontra/daikin_residential_altherma/issues/226). Please migrate to the daikin_onecta integration which supports the Daikin Altherma but also other types of Daikin devices.

Daikin Residential for Altherma 3 Heat Pump

Home Assistant Integration for Daikin Altherma 3 Heat Pump (natively for models BRP069A78 but users have good experience also for BRP069A62 and BRP069A61 despite they have not been tested).

This integration can coexist with the [daikin_residential] integration (https://github.com/rospogrigio/daikin_residential).

This integration is maintained by @speleolontra and @jwillemsen.

Installation using HACS:

Install with HACS: Search for "Daikin Residential for Altherma 3" in the default repository,

Manual Installation

Copy the daikin_residential_altherma folder and all of its contents into your Home Assistant's custom_components folder. This is often located inside of your /config folder. If you are running Hass.io, use SAMBA to copy the folder over. If you are running Home Assistant Supervised, the custom_components folder might be located at /usr/share/hassio/homeassistant. It is possible that your custom_components folder does not exist. If that is the case, create the folder in the proper location, and then copy the daikin_residential_altherma folder and all of its contents inside the newly created custom_components folder. Then you have to restart Home Assistant for the component to be loaded properly.

Using config flow

Start by going to Configuration - Integration and pressing the + ADD INTEGRATION button to create a new Integration, then select Daikin Residential Controller for Altherma in the drop-down menu.

Follow the instructions, you just have to type the email and password used in the Daikin Residential App. After pressing the "Submit" button, the integration will be added, and the Daikin devices connected to your cloud account will be created.

YAML config files

Just add the following lines to your configuration.yaml file specifying the email and password used in the Daikin Residential App, and the Daikin devices connected to your cloud account will be created. After making changes to your configuration.yaml file you need to restart home assistant.

daikin_residential_altherma:
  email: 'your_email'
  password: 'your_pwd'

Setting the log level

If you'd like to see more granular logs, to investigate the communication or for other debugging purposes, you can set the log level in the Home Assistant config. The following lines can be added to set the overall log level for the component:

logger:
  logs:
    custom_components.daikin_residential_altherma: debug

If you only want to change log level on a per module basis, you can do that as well, for example if you only want debug logs for the climate:

logger:
  logs:
    custom_components.daikin_residential_altherma.climate: debug

Thanks to:

This code is based on @rospogrigio work that in turn is based on @Apollon77 work, in finding a way to retrieve the token set, and to send the HTTP commands over the cloud. This integration would not exist without their precious job, my job was to try and debug Rospogrigio's code to adapt at JSON from Altherma 3 controlled by Daikin Residential App.
