I got into the whole smart home scene right when smart tiles was being retired. Being a web developer/designer, that was the one thing I was really excited for. Something I could just jump in and redesign to suit my needs.
Fast forward, I found House Panel from @kewashi with an open api to do with as you please.
So granted, I may have gone a little overboard, but it has been so much fun building. Still have a ways to go, but it is a good start.
