I’ve been reading and wanna try to setup a screen for Kiosk, but am unsure of hardware
I have a couple of older kindle fires with cracked screens that I could play with, or I could buy a cheap android tablet
converting the fires sounds fussy. rather not since they are already near end of life because cracked screens
OR, get one of the no-battery touchscreens that is occasionally mentioned, but those are not exactly cheap either (but you get what you pay for, right?)
I’d prefer touch screen, no battery, USB power, wifi, and cost effective.
Watchout for the very cheap tablets. I have several Onn from Amazon of different sizes. One died already. Generally the battery that goes. And, I keep them between 25% and 80% SOC.
I had a couple RPI 3 Bs in a box. Grabbed a couple screens for them and am messing with those now too.
Playing Devil’s advocate, Fully Kiosk Browser has (or had) a download link on their web site for an Amazon Fire-specific .apk installer package. You can side-load it onto a Fire without going through the hassles of liberating the device from Amazon’s claws, with a footnote that their ads are only displayed on the lock screen and never displayed if the screen is unlocked/on 24/7…
I have 2 Fire HD8s running the HA companion app with Fully Kiosk. It was a bit of a challenge to find and install all the .apk files for Google Play etc to install the HA Companion app, but I like a challenge and it does feel good to have done it a couple of times, but, as Nathan says, my time is too valuable to be constantly fettling them to keep them working. One seems to work mostly okay, the other is just a nightmare at times. Contrast that with the only other Android tablet I have, a Lenovo A7 Lite, that works flawlessly, and I think you can guess my opinion of using Fire tablets as HA wall tablets.
Used Samsung or Lenovo, or watch Warehouse deals at Amazon for the same, are the best options. They have battery management options built in. Don’t bother with the fire, particularly with cracked screens.
Then you could upgrade to a batteryless Android screen later.
I used Fire Tablets with Fully Kiosk Browser for years and have disliked every moment of it. I am slowly changing to other cheap android tablets around $80USD or whatever is on sale. I would avoid using Fire Tablets, they are usually cheaper but not worth it IMO.
