Hello,
I was wondering if there is some touch screen display for example use in each room … I lost a link on some and can’t find something reasonable price.
I can Google displays but these are more then 100usd, which seems to be pointless as one can buy amazon fire for much more cheaper…
Any idea here? It’s fine if it’s connected to rpi.
Thanks!
It depends on how “DIY” you want to go but there are quite a few ESP32 displays that could be used, it will take a lot of work to set them up, and the result may not look as “professional” as a lovelace display. But they will be a lot cheaper.
The Amazon fire tablets can be a pain to remove all the limitations amazon puts on them. Something like a Lenovo m10 would be a good choice but will cost over your budget. A screen connected to a RPi will likely cost nearly as much by the time you have it nicely cased etc.
My fire tablet has been on my wall for nearly 3 years now and is fine, but it was from a previous version of fire OS that was easier to remove stuff from. But it still struggles with camera feeds, and can sometimes feel under powered.
It depends on your requirements. I have some HASP (Home Automation Switchplates) in my home that are very wife-accepted:
Just recently, someone on this forum told me about DeX on an Android phone. I had never heard of DeX before that thread, but DeX lets you use a portable 16-inch touch screen on your phone.
The latter looks interesting, but it’s a bit pricey with $150 for the monitor plus an old phone.
As others have said, it kind of depends on what you define as reasonable. I use the Raspberry Pi Touch screens on three displays. Here’s the newer version of that (it now does 720p).

Add a Raspberry Pi (a RPi 4 would be more than enough) and auto start a web browser into HA, and you’ve got a touchscreen controller for under $200. OK, maybe around $200 by the time you get a case and a power supply.
Screen size and resolution are two factors that need to be considered.
I use a couple of Guition ESP32-S3-4848S040 displays. At 4" and a 480x480 resolution, they are adequate for displaying basic text. Having onboard relays & mains power supply also means they can double up as a smart light switch.
You can’t compete price-wise against a general purpose mass-produced consumer device, especially when they are on holiday sale for half price like they are right now. Stock up and save… 
Does it have to be new? I have a couple of reconditioned Nexus 9 tablets (Android 7, I think) running Fully Kiosk. They cost about 20 GBP on Ebay. At that price you can throw them away when the battery bloats.
Seems that nexus 9 might be the best in size/price
Two things to watch out for: excessive battery bloat (there’s nearly always some, but usually not too bad) and peeling of the laminate on the screen. This sometimes starts to go round the edges, giving a bubbling effect.
Not apples and apples comparison. Amazon subsidizes the cost of the tablet because of that you don’t have full control of it.
I started with two Amazon fire tabs for displays and I only ever got one deployed because of the royal pain I had trying to get it to behave as I want and I didn’t feel like doing it twice.
So when you’re thinking of cost. That MUST be factored in. I will tel you for a fact I will never deploy another fire tab for this case. Way too much work to keep Amazon from jacking it up.
The other tablet SEEMS more expensive now but your time is valuable…
I ended up using a similar setup with some additional software to make the experience more user friendly:
@leukipp do you mean that one?

i found waveshare which is chaper but not idea regarding the quality?
thanks!
Thats the older version. Touch Display 2 is fully compatible and tested:
https://www.raspberrypi.com/products/touch-display-2/
and is there some mayor benefit via old one?
Yes, Resolution: v1 has only 800 x 480, v2 has 720 x 1280.
Compared to the Waveshare product the official screens use a single DSI (flat cable) connector instead of HDMI + USB.
It still may partially work. Have a look into the hardware compatibility list, where another HDMI display has already been tested: touchkio/HARDWARE.md at cfbc391a52785593204dd76bde96114a7fc9018e · leukipp/touchkio · GitHub
@leukipp i believe you meant https://www.amazon.de/gp/product/B0BWJ8YP7S?th=1
Yes, but feel free to order any other touch display with HDMI. It will most likely behave similar to the tested LAFVIN.
So for full support (display power and brightness control via MQTT use the official screens), if you can live without brightness control (only display on/off) use some cheaper alternatives.
got it, is the brightness control useful? maybe in the main room, during the night?
Yes, night time or some fancy transitions (dimming effect) may be some use cases. But it’s not that important. You can also just ignore the MQTT integration and use the RPI built-in screen on/off features as described here:
The device from this thread Is this the perfect standalone tablet for HA? looks pretty good as well. Way cheaper than a Pi plus display.
I don’t know how the second hand market is where you live, but I can get refurbished 10" Android tablets with warranty for around 100 euros. Those aren’t the most fancy ones but plenty good enough for display/control of HA.
