HA Solvis Heating custom component
If you don't manage to get the data from your heating device, please enable debug logging and log_response. This will provide you with information for continued investigation.
If all of this doesn't help, use the home assistant forum. I cannot give everyone personal assistance and please don't create github issues unless you are sure there is a bug. Check the wiki for help and other details on the functionality of this component.
The solvis_heating custom component uses the XML datainterface of the solvis remote extension of the heating system.
The Solvis Heating Device is providing a lot of information about its state. To access this information the Heating device must be acessible via a computer network. Solvis provides the solvis remote as an additional device to make the heating available. Beside the officially documented http interface, the remote also provides an xml interface.
This allows you to get details from your Solvis Heating device and integrate these into your Home Assistant installation.
Before being able to use the integration, you have to own a solvis remote device and have it attached, configured and available in your network. The communication with solvice remote and decoding of the returned data is done by the pypi package sc2xmlreader.
Since Solvis SC2 Centralcontroller version MA205 (or higher) the data can be retrieved via the MODBUS interface (see Solvis Heizung via Modbus auslesen und steuern)
If you have an older Centralcontroller version, MODBUS is not available. But the XML Interface is available (currently i don't know since which version of SC2 - may be someone can tell me)
Due to my own heating system, I could only test the XML interface agains a SolvisMax 6 with Solvis Remote 200. As far as I know, it should be possible to use this against other system as well, as long as there is a Solvis Remote available.
The provided data can be integrated into HA Dashboard.
Sample Dashboard for heating overview
Sample Dashboard for solar details
Burner consumption and solar yield are also available in the energy dashboard (unfortunately und the label of "gas consumption" ...)
To add the values, just add "burner consumption" and "solar yield" to the dashboard:
...and the values will be part of the enery dashboard:
- Install the pypi package sc2xmlreader at your HA installation (prerequsite)
- Install manually by copying the files in 'custom_components/solvis_heating' to a new 'custom_components/solvis_heating' directory in HA config directory.
- Create 'customize.yaml' in config directory and add
sensor.solvis_remote_volume_stream_solar:
unit_of_measurement: 'l/h'
sensor.solvis_remote_volume_stream_warm_water:
unit_of_measurement: 'l/min'
- Restart HA
- In HA Setting - use "Add Integration" and search for Solvis
- Configure the integration test (ui configuration)
- Configure your dashboard
