I want to build a control panel into the bathroom and two bedrooms. Its primary use would be to control the music system (via HA of course), but could potentially perform some other HA functions too. I’d probably write some little software for it.
I had a chance to use the device I posted above, and quite liked it. Very unobtrusive. A tiny square screen like that is too small for having a nice touch interface, so the bezel buttons work pretty well.
Maybe I should just go with a slightly larger touch screen then.
but I have not tested it yet. Given it is android it will have a browser and can therefore control HA. It also has a built in amplifier and sepaker terminals, mains powered, RS485, a switch connection for doorbell (dunno really what that does).
I was hoping you’d post about them, I remember you mentioned you would buy one of those. They look very nice. Please let us know your feedback when you come around trying it out !
Ah, looks like you might be in Europe too, with that concrete/brick wall rather than wood and drywall like in the USA?
Did you make the whole in the wall yourself? How did you do it? Are those wires in the wall just mains power?
I want to do something very similar however I’m hesitant to make a screen-sized hole in the wall. What happens when eventually the screen needs to be updated and you cannot find one that is the exact same dimensions?
Do you have ethernet running to the pi too or is it wlan? Does the wlan work well surrounded by concrete on 3 sides?
I’m quite torn between the dedicated screen + external pi vs wall mounted tablet options.
An android tablet is obsolete within a few years, even if it is supported by 3rd party android distros like Lineage, you can’t count on updates there for more than 5 years or so. Also an android tablet has less options when it comes to software. I’d much rather a linux system I can ssh into and setup whatever services and scripts I want. But an android tablet is much easier when it comes to mounting options. I can wire a usb charger into mains and have the tablet mounted over it. No new holes required.
But a separate screen can have its compute hardware upgraded separately, and you aren’t restricted to old buggy Android versions. I imagine a screen will really last a long time as well. But the big negative is a huge mounting hole.
@JKW Do you always have something on the screen? Even at night? How dark is the iiyama t2234mc when blanked (but still on)?
Edit:
I’ve bought one of these Waveshare AMOLED 5.5" touch displays. I’m curious to see what I can put together before making a big hole in my concrete wall. It is too bad that a rpi doesn’t fit inside the electrical outlet box in the wall.
I found this interesting product that would make mounting tablets more seamless TecLines TNT001 is the in-wall 220v → USB charger and they have an assortment of flush wall mount tablet holders.
The charger itself could be used for a Waveshare + RPI combo if you could DIY the enclosure.
Hi JKW, I have Pi 4 model b running home assistant, and would like to connect touch screen like yours however i have some doubts before i purchase the screen.
1- the touch will work normally once i connect the touch usb? Or it should be configured.
2- what options should i look for when purchasing the screen to make sure it is compatible with Raspberry Pi running home assistant
3- Do you know other screen brands that can work the same.
Just a quick comment on this, we’re using these Iiyama touchscreens in the office. They’re really really good (the IPS ones with capacitive multitouch). If I’d ever do a fullsize wall mount touchscreen, I’d definitely go with one of those. And they have quite a bit of choice too
I don’t think Iiyama sells directly to end users, you’ll have to go over a distributor. Amazon stocks them, or the usual big online PC retailers. Over here they’re between 200 - 400 Euro for the 22" to 27" ones, depending on where you buy them from.
If you’re after the 98" ones for your new interactive HA wall, then all bets are off
love the cabin!
