If you have a good budget, get a real automation platform installed. The best wall mounted tablet options are an IPad, and LaunchPort. If you’re on a tight budget, you need a ST hub, and Action tiles on an HD8 or 10. and buy the mount from a dude named bob. (literally). and you can get a POE splitter for power. takes a poe cable and splits it to a 5v 1a output for charging. iPad and launchport is where it’s at though.
