Hi,
I have written a custom integration for the Drooff fire+ combustion control system, which is installed in some Drooff fireplaces.
Installation instructions and an overview of the entities provided can be found at GitHub - tehlers/ha-drooff-fireplus: Drooff fire+ integration for Home Assistant.
This custom integration has so far only been tested with a single Drooff fire+ instance. Experience reports, feedback and suggestions for improvement are welcome.
All the best,
Thorsten
