Bought this awesome “invisible” touch sensor that works through many surfaces up to 25mm and integrated it into Home Assistant using a Shelly i4DC. Now I can use it to control anything. So cool I’m considering installing a few around the house or even making my own high end marble tile wall switches.

Super easy – no coding, no soldering.
