Another use for an old tablet
(slrpnk.net)
This one is nothing fancy, but it fit our workflow well. My SO has always saved recipes to a pinterest board - normally she brings a laptop to the kitchen and sets it up on a chair.
We finally took this tablet (came from corporate ewaste) and stuck it to the wall. It's too old for most apps but it seems to work well for this. We installed pinterest, and a podcast player. Eventually I'll check if there's a good replacement OS for the expired android version, but I figure we'll do a bit of a trial run, see how it's working for us and what we need, before starting with that.
I'd like to have more of these set up for home assistant controllers.
Some day, in the distant future, homes will be wired for these panels and the "switches" won't be directly wired to the lights. It's currently more difficult than it seems to make this look smooth. Ideally, you'd want the power connection in the back of the phone/tablet to plug into an outlet (USB-C) recessed into the wall, with a holder on the wall that the tablet could slide into and (rarely) out of.
Think Star Trek: TNG wall panels next to the doors in that show.
It's already easy to set a different screen for each switch panel, with an option to go into more detail.
Right now I use a combination of smart switches and smart bulbs. Smart bulbs for colors, primarily. Smart switches integrate better with current technology and standard bulbs.
Plus the Matter/Thread standard isn't ubiquitous yet, so it's kind of better to wait for more adoption there.
