With a python module, i wrote earlier, for remote control of hegel amplifiers and an MQTT queue i integrated the hegel in Home Assistant and Node-Red.
It is now possible to control all functions of my H190 and H390 with standard home automation components and apps.
So native volume control, input selection, on and off .
At the moment it is just a very basic script but soon will be a docker container with a bit more functionality and configuration.
if you use it, please let me know here in the community.
This way i know that i can put time in it thus not wasting it.
This is the work of a few hours tinkering.
Just for kicks and giggles, here is the Proof of Concept code.
It works, but use it at your own risk.
The hegel python module is not on pypi yet but will be.
