What’s everyone using for displaying wall mounted dashboards?

So, I’ve more or less got the green light from my other half to put a HA dashboard up in the kitchen and have a nice area on the wall ear-marked where cable management etc shouldn’t be a problem. So the big question is… what setup do I go for?

Considering a Galaxy A9+ tablet as I believe it can charge wirelessly and with the right mounting I could even design in such a way that I can take off the wall if needed? (Or a similar Amazon tablet, either Fire HD 10 or Fire Max 11?). I’m assuming all of these can be put into kiosk mode or just full screen browser? Other features that would be helpful are for the screen to wake with movement and show some form of screensaver image when no-one is nearby (but still visible for the far side of the room).

Other option is to build a raspberry pi mounted onto the back of a touchscreen display which is likely to be a little more initial outlay and a bit more of a project but could give better long term flexibility.

I’m really stuck on which direction to go down…. cost isn’t really a factor and ideally I’d like the largest touchscreen display that’s feasible but keen to hear from other’s experiences before taking the plunge. Thanks in advance!
