Flush-Mounted Raspberry Pi Home Automation Touchscreen

Raspberry Pi computers make great hubs for home automation, and their 7” touchscreens make a perfect way to display this info to the humans they’re meant to serve. One problem, however, is that if you want to mount one of these screens on the wall, you have to run a cable somewhere else for power, and mount it in such a way that it juts out significantly.

If you’d like to forgo external wires, and don’t mind doing a little minor home electrical work, home hacker “peter_3d” has a great solution. His setup uses a three-gang electrical box embedded into the wall to house the back of the touchscreen, Raspberry Pi, and the USB transformer needed to actually power this device.

Since the touchscreen is too small to cover the electrical box, he 3D-printed a black bezel to go around it, as well as partitions that go into the gang box. These partitions separate the 120 volt section and transformer from the USB connector, making setup and troubleshooting safer when needed.

If you’d like to build your own, 3D printing files can be found here, and you may also want to also check out the Home Assistant Dashboard (HADashboard) that he’s running.
