Hi all,
I always wanted to be able to control my Faber fireplace from within Home Assistant. I have the “Aspect Premium RD L” model. But there was no integration available … until now 
Over the christmas holidays I created a custom integration for the Faber ITC controller.
Check it out here and install it via HACS: https://github.com/konkz/home-assistant-faber-itc
What I did: I downloaded the Faber ITC App v3 from the official App Store and captured the network commands sent by the app to the ITC Controller of the fireplace. I reversed the TCP protocol and discovered the commands. In my GitHub repository you will also find a description of the protocol if you want to look deeper into it.
In my custom integration I simply resend the commands that are also used by the official faber app.
This way I can now fully control the fireplace through HA, in automations etc.
Note: this only works with fireplaces connected to the network via LAN or WiFi. It currently does not support Bluetooth.
If you also own a Faber fireplace feel free to try this integration 
I will not be able to give any support, but if you want to tinker with the code, you can fork the repo and send pull requests if you have any improvements. Everything is publicly available.
cheers
