Just finished my wall mounted tablet project and wanted to share it with you for inspiration. We’re loving this thing, so I highly recommend doing it if you’re on the fence.
My wife wanted a huge tablet flush mounted with the wall, so we ended up going with a Samsung Galaxy View (18.4" screen), which we got on sale for $344. Another option is the TCL Xess (17.3" screen with built in Alexa). We have a google home, so I didn’t need the alexa integration and the TCL was a bit too pricey.
I cut a hole in the wall and made a custom bracket out of some old MDF I had lying around (I recommend using something with more strength if you do this. The weird cutout in the 2x4 is to compensate for the weird hump on the back of the Galaxy View.
I ran power through the wall with a 14/2 power cable and then made up the ends like an extension cord (the other end of which runs into my utility closet and plugs into a plug in there, allowing me to easily unplug this device if needed). I tried SmartTiles, but much preferred to just use SharpTools and then create custom widgets to trigger routines/actions. For the interface, I used “Total Launcher” which basically is a free-form launcher allowing you to make whatever interface you want.
We mainly use the tablet for viewing our family calendar, accessing our shopping list (todoist, added from google home), viewing recipes (pepperplate), controlling smartthings, and viewing our outdoor security cameras (tinycam). I also use blue iris, which plays a doorbell chime on the tablet when someone approaches the door.
I built a frame out of some old trim I had and attached it using magnets so I can easily pull it off to press the power button when needed. One thing we love about the tablet is the ability to have it display our family pictures when not in use like a screensaver (using google daydream). Let me know if you have any questions!
