In short making a wall mounted home assistant dashboard is very easy some have resorted to simply embedding tablets in the wall, but for those after size there’s still another option! Essentially it involves installing Android OS on a raspberry pi & connecting it to a monitor which touch input. In a prior post I made my solution was a tv + ir touch frame + the rpi running android but i wanted to give detailed steps and a better way of achieving the same goal. IR touch frames aren’t bad but they often never fit any tv’s frame exact to size and require you to mount it to the tv in a way that seems very DIY. So why not just go with a monitor that already has touch input in it and direct to the rpi and this is the guide to do so along with some screen options…
Installing KonstaKANG LineageOS on Raspberry Pi 5 & Pi 4
Notes:
• These are community, unofficial builds for advanced users.
• Flash on a fast 16–32 GB+ SD or NVMe.
• TWRP is built-in; we’ll use it for the resize and GApps steps.
• Use MindTheGapps (minimal GApps), ARM64, Android 15 (LineageOS 22.x).
Raspberry Pi 5 — LineageOS 22.2 (Android 15)
What you’ll need
• A computer with an SD/NVMe writer
• Raspberry Pi Imager → Download
• A reliable PSU, HDMI, keyboard/mouse (or SSH/VNC later)
1) Download the ROM
• Fresh install (full image .zip → extract the .img)
– Get the current Pi 5 image (direct host link) → click the lineage-22.2-…-rpi5.zip in the “Downloads” section to fetch the file from the external file host.
– After download, unzip it once to obtain the .img.
• OTA package (only if updating an existing KonstaKANG install)
– Pi 5 OTA — 2025-08-26
2) Flash the image
• Open Raspberry Pi Imager → “Use custom” → select the .img you extracted → write to SD/NVMe.
• Safely eject.
3) First boot
• Insert media → power on → wait for the initial boot to finish (first boot can take several minutes).
• Complete the LineageOS setup screen (you can skip network for now).
4) Enable Advanced restart (for TWRP)
• Settings → System → Buttons → Power menu → enable Advanced restart.
• Hold power → Restart → Recovery (boots TWRP).
5) Expand storage to full card (resize)
• Download the resize add-on on the Pi or another device and copy it to internal storage/USB:
– KonstaKANG-rpi-resize.zip (direct host link) (look for “How to expand storage?” in the guide; click the file to fetch from the external host)
• In TWRP: Install → pick the ZIP → swipe to flash → Reboot → System.
• Storage now uses the full capacity (after the reboot completes).
6) Install Google apps (MindTheGapps)
• Download (on Pi or another device, ARM64, Android 15):
– MindTheGapps 15 ARM64 — Latest
• Reboot to TWRP (power → Restart → Recovery).
• Install → select the MindTheGapps ZIP → swipe to flash.
• Wipe → Factory reset (required by the maintainer).
• Reboot → System → complete Google setup (Play Store will appear after first sync).
Optional add-ons later (from TWRP): Magisk, Widevine L3.

Tip: If you’ll use this with Home Assistant, install the HA Companion app from Play Store after GApps, then pin it or add it to your launcher for kiosk-ish dashboards.
I really recommend the touchwo screen, they actually make the koisk we see in mcdonnalds and other fast food chains (you can even buy one of those as well for those of you who use HA for business and ever was interested lol)
Mounting Options
Also keep in mind these monitors also go portrait mode as well as traditional landscape and for somethings your going to want to quickly be able to rotate the display and change the view to portrait/landscape. So shop vesa mount for your display that allows for 180 degree rotation.
Something like this but ensure its to your screen size and wont be visible when mounted.
Great timing! I have spent an insane amount of time reading and thinking about touch displays for HA in our new house. Your post is spot on and provides the best setup i have seen so far.
One question though, is a 1080p screen enough? No need for 4k, especially with the larger screens? What are the largest size(s) you have used?
Firstly thank you, the tireless nights i spend researching lol.
And 1080p is enough, however the benefits of a greater resolution comes in when you have large dashboards with tons of data you can fit more on screen before needing to scroll. Otherwise 1080p has been no different than how HA looks on my PC screen. And i have used 4k with tv’s + ir touch frame but i moved away from that type of setup. And the largest size i used was 55" but my space looks best with 43"
But the larger screens tend to be in 4K 55"+, what sucks is before the pandemic all of these things were super cheap because of lack of demand and tariffs. But people are catching on and your seeing more Chinese brands coming to amazon witht their touch related products.
Thanks for the various monitor suggestions. I would really like to find one with integrated speakers AND microphone … havent found one yet but will work around that …
Question though - why Android on PI rather than RaspianOS? What is the benefit of loading android on the Pi, rather than using its native OS?
I am working on designing something for my kitchen so one of the 27" options sounds about right, just was planning on doing with native PI solutions and wondering the benefits of the android path
There are a few monitors on that list with built-in speakers (e.g., from TouchWo and GreenTouch), though their audio won’t rival a TV’s—these are rugged commercial displays built for 24/7 kiosks, casinos, malls, arcades, and public spots. You’ve probably interacted with them unknowingly under various rebrands. For mics and speakers, check TouchWo’s site; they offer custom sizes and might have options, but since you’re using a Pi, you can always add external ones cheaply later. They’re pricier because their commercial grade. Also dont sleep on the first monitor in my list, i also have that bad boy, its actually verry good and come with audio, do remember you can plug webcams into the pi or you can literally use pi cam and built it into you wall .
On the OS front: Raspbian (now Raspberry Pi OS) is solid, but it can feel clunky on Pi hardware when running a full desktop limited RAM and CPU often lead to lag in multitasking or media-heavy apps. Android, optimized for low-power devices like phones, runs smoother on Pi, boots faster, and has a familiar interface your family already knows (plus easy access to the Play Store for apps). It’s great for a kitchen setup like yours think touch-friendly UI without the overhead. TouchWo even sells Android-integrated versions, but pairing a plain screen with a Pi keeps it modular, cheaper, and more power-efficient than all-in-ones. If you hit snags with Android on Pi, LineageOS or similar builds are straightforward to flash. Android is designed to run devices powered by battery you keep in your pocket for hours without a charge, in short its lightweight and efficient designed for hardware limited devices. the pi runs it smooth. But if you truly want a desktop environment ditch pi, get a cheap nuc. I did a post about how much eclectic your saving by going pi vs nuc and any sain person would go nuc, way more powerful add cheap consumption. Ill link it when i get some time
