@allard77 is that a correct link? i cant see what device is he mentioning? thanks
I seem to have accidentally linked to a reply deep in the thread. I updated it to link to the top post now.
(or you can type" Lenovo ThinkSmart View" into your favorite search engine)
@leukipp just odd question… is there any point to buy old rpi display, ie not a version 2?
thanks
Short answer: No, "new is always better”.
Long answer: Maybe if you run into limited availability (v2) and need it right now, or if you are lucky and get the hands on a cheap used one (v1).
hello,
maybe odd question … assuming i want to have a touchscreen inside each room, is there a way to have one control unit for these screens? or do i have to run for each screen separate rpi hw?
thx
anyone any idea here? thanks!
You need both a touch display and “something “ to run a browser or some app (like HA comapanion).
A tablet has both, a simple touch display only that.
As already reported there are simpler displays that can run custom sw like esp-home with which you can interface HA (but not run the “usual” dashboards).
Try to read around there are plenty of guides here and on the internet
@wrongisthenwright thanks
and thats my point… in case u need attach to the display RPI, how to make it … resess it into the wall (Create a hole in the brick wall) or how do ppl do this.
The RPI is only one of the available choices (and it wouldn’t be my first)…
If you plan to use Raspberries with additional touch screens in your rooms you’ll need to encase the RPIs and their power supplies in the walls…
If you need to display dashboards in different rooms I’d go for cheap no brand android tablets, maybe chosing one that has LineageOS images available, in this way you’l be protected from dubious ROMs.
If you only need to activate simple switches/scenes/commands/actions from a specific room (eg. turn on light, raise curtains etc) I’d choose something that can fit a normal switch wallbox, eg NSPAnel from Sonoff or better shelly wall display.
These are smaller (so not good for history graphs) but cheaper.
Some of these display had embedded temperature sensors so can be used to regulate climate coupled with switches/TRV etc
ah got it, so basically my initial thinking was wrong… as u said encase RPI into the wall … not sure if thats a good idea (but i am going to rebuild the flat,… .so might be worth compare to tablet?)
thanks
Looking at it from a purely financial perspective, it’s not a good idea. Pi + screen will cost you more than a half decent tablet like a Fire.

Obviously there are other ways (e.g. tablets) to do this, but if you go Pi + touchscreen route, you can try google image search for inspirations, and this is fairly common.

A variation is to do the Pi + screen setup in a (thick) picture frame, which sits on top of a wall outlet.
Obviously a tablet can do something similar also.
Another variation for tablets is to find some “barebone” tablets, or mod the tablet you have, so that would allow direct power wiring without any battery, because the battery itself would introduce some downside, as mentioned above.

Finally, the most critical missing information for you, @phier (maybe you have answered but I could not find any) is this: What exactly are you trying to achieve with the touch screen? What’s the use case?
Because, there are also these type of devices (1, 2, 3) you can put onto your wall.
So, please, John, this thread is 30+ posts deep already… please elaborate your use cases before asking recommendations.
What are you trying to do really? “I want to put a touchscreen on the wall” is not enough - you will want to provide 1 or 2 steps further, otherwise people here could find it difficult to help you.
