Time to DIY!
Waveshare touchscreen for pi, 1200x800 is a good price and for home assistant that is fine. $70/75 for 8inch/10.1inch version. (10.1DP-CAPLCD)
Raspberry pi 3/4/5 can mount directly on the back of it. For whatever outrageous price Pis are now. (Around here, a 4B/4GB is 60€.
Wave share PoE hat for $20
Assemble it like Lego, put it in a wooden frame or 3D print, done. Around 160 USD plus shipping for a full build of a POE battery-less touchscreen display that runs full Linux of whatever flavor. (And is quite overkill as far as power).
You could probably do it even cheaper with an orange pi zero 3 with a PoE to USB-C converter or a Banana Pi BPI-P2 Pro IoT which has PoE built in.
It is cheaper than a tablet and strips out the useless things like a battery, camera, really high DPI display, LTE radios, etc… For a simple home assistant kiosk.
But yeah, epaper displays are 3x the display cost without touchscreen. Though in my opinion, epaper is better for static non-interactive sensor display which can run on battery with an MCU for almost no power because it only has to update once an hour or so.









Bazzite uses BTRFS, but not snapshots I think.
Opensuse microOS flavors go all-in on full system snapshots but that means they also have a bad grub encryption unlock interface (instead of Plymouth). I have had some funky things with it like it missing keystrokes and if you get it wrong once, you have to reboot your entire system instead of just retrying.
Other OS’s use home folder snapshots only or something like that?
The different variants are not quite clear to me.
