On Amzn, there are nicely framed, wall-mounted control panels for proprietary home automation systems. What are people using for HA? I'm leaning toward trying to wall mount tablets, but I'd need 3, and cost starts to factor in. Mounts are a problem; I want it to look as built in as possible, but most mounts aren't picture-frame style. The ones that I've found that are, are designed for specific tablets, and not the low end cheap ones. I don't have a 3D printer, so I'm limited to mounts I can buy.

I like some projects here I've seen using eInk - that's the ideal solution! Is there a source for pre-fab Android eInk wall mounted control panels, or are what I've seen bespoke projects?

I'm not opposed to gross wiring, and am not afraid of cutting holes in dry-wall... it's really the mounting that I'm stuck at. Android 7-10" tablets sufficient to run the UI would probably work, and I can probably even figure out wiring the charger, if I could just get some nice picture-frame style mounts.

What are your solutions that you think is pretty neat? Or products that I may have missed?
