Hi everyone,
I build a little hardware alarm panel for people who don’t have a phone and can’t be integrated into Home Assistant in another way.
You can find the code and more details on GitHub. I have never really learned or done any proper C coding so don’t look to closely at my code 
(or send a pull request!).
I hope someone finds this useful! 
Features
- Change alarm system mode (away, home, night, disarmed)
- Welcome people arriving by their name
- Turn off all lights (when you leave for example)
Best,
Paul
