Absolutely - it's just that with the RPi you can run a bunch of other stuff behind the scenes which is nice. The 7" screens are a lot cheaper of course. With FPOS you could livestream cameras in a browser tab etc.
Otherwise I too want a good cheap tablet that has some way to run in "Kiosk" mode. Note: if you go into developer mode on an android (and kindle fire) you can set an option for screen on when connected to power.
Just checked on XDA Flashing firmware for the 2018 8" model involves shorting a test pin in the back. No big deal but maybe a little trickier than some would like.. still good price and I just ordered one (8" HD with special offers) to play around with..
I may tackle the rom and root next because I like to do those things, especially to Locked down devices like an Amazon tablet or Samsung phone. But for what I wanted to do with the dashboards, I didn't need to hack it last night.
But for anywho who was following the thread, i figured I'd share the outcome even without rooting.
Now I'm torn on whether a 7" would be too small. May need to order one to find out.
Double confirmed. Took me a few tries. Missed a direction here, typo there, but went smoothly.
Time to go ROM shopping. And maybe order another one of these just for fun. Still not sure I need more than the Fully Kiosk app out of the Play Store, though. Hmmmmm... Maybe save the money and put it towards a nice wall mount.
I bought 2 more just to have before they shut down the vulnerability. It was cheap enough. That Fully Kiosk worked well except this morning had a bit of a refresh issue after I turned the screen off last night. Not sure if it was FK or the locked down dashboard. It was not responsive until I swiped right and tapped on "go to startup page..". Also the tablet still has ads on the lock screen so now need to get rid of those too..
Here is my "test" setup in our bedroom - didn't get too fancy with the DB may eventually switch to HousePanel.. Another thought would be to take the back off and fasten it to a wall then pop the unit in again. Should act as a good holder. Also if really serious you could get those right angle micro usb plugs and fish it inside your wall with minimal side cord exposure.
I have two tablets and one of them has ads but should be a non issue if you set up fully kiosk settings correctly. If you get the plus license, you can set up a screensaver and turn the brightness to zero. I have the kiosk screensaver set to 120 seconds. I have motion turned on for front camera. After 120 seconds, it goes to a blank screen saver and comes back on Showing the dashboard screen when motion in front of it detected. No ads pop up. Now I also have been having the refresh issue which I would love to know the cause. Sometimes I have to refresh the dashboard as it will still show some of my lights on that I turned off from another tablet or at the switch.
If you go to the Konnected website and look under products, there is a member selling through then that makes 3D printed wall mounts for the fire tablet for about $30. They are pretty good but some don’t like the finish from the 3D printing process but I think they look and work great. I did have to Dremel the inside edge a little to get my 90 degree cable to fit so the tablet was perfectly centered.
