Important
Installation directly through HACS is not yet available because the integration is not yet included. This process will take some time. In the meantime, please use the manual installation method or click the below Open HACS Repository button.
- Ensure you have HACS installed and configured in your Home Assistant instance.
- Open the HACS (Home Assistant Community Store) by clicking HACS in the side menu.
- Click on Integrations and then click the Explore & Download Repositories button.
- Search for "Dantherm" in the search bar.
- Locate the "Dantherm Integration" repository and click on it.
- Click the Install button.
- Once installed, restart your Home Assistant instance.
- Navigate to your Home Assistant configuration directory.
- For most installations, this will be '/config/'.
- Inside the configuration directory, create a new folder named 'custom_components' if it does not already exist.
- Inside the 'custom_components' folder, create a new folder named 'dantherm'.
- Download the latest release of the Dantherm integration from the releases page into the 'custom_components/dantherm' directory:
- Once the files are in place, restart your Home Assistant instance.
After installation, add the Dantherm integration to your Home Assistant configuration.
- In Home Assistant, go to Configuration > Integrations.
- Click the + button to add a new integration.
- Search for "Dantherm" and select it from the list of available integrations.
- Follow the on-screen instructions to complete the integration setup.
If you encounter any issues or have questions regarding the Dantherm integration for Home Assistant, feel free to open an issue or start a discussion on this repository. I welcome any contributions or feedback.
Note
Preheater and HAC module functions are currently unsupported due to limited testing possibilities. If support for these functions are desired, please contact me for potential collaborative efforts to provide the support.
Currently supported languages:
Danish, English and French.

This is a modified version of a dashboard card posted by @cronner on Home Assistant Community. This will show alarms, filter remain level and change according to the current bypass state. Kinda like the Dantherm app.
The details for the above picture-elements card (challenging).
I might consider creating a custom card based on this in the future.
To integrate this into your dashboard, begin by downloading and extracting this zip file. Copy the contained files into the "www" folder within your configuration directory.
Next, insert the following code into your dashboard. If your Home Assistant setup uses a language other than English, make sure to modify the entity names in the code accordingly. You also need to create the below helper template sensor.
