So I wanted to create realistic looking buttons (or should I say I was messing around with them lol) these are just testers though., requires card mod and custom button card.
realastic buttons for home assistant - YouTube (22 seconds long show how they look with color changes) there is another rather long winded 8 minute video explaining how to make one for your light on the channel, no dull voice just text over video
