Hi,
Last year I bought a raspi with a 7" touch display which I wanted to convert into a digital picture frame including some functionality to control my lights via openHAB. The project got a little bit out of hand and now I use it also on a tablet as a control screen for my home automation.
It looks like this:
I’d like to share my code (with more screenshots and configuration examples), so maybe more of you enthousiasts can enjoy the result.
It is a webserver written with Python/flask, so you can load the gui on any device with a browser. The configuration is read from an openHAB sitemap. Although it needs some specific structure and specifically named sections, it is still relatively flexible and easy to configure.
Feel free to try it out if you like how it looks!
