It is possible to develope hass.io addon to show chrome app on host screen (raspberry pi 3 + hdmi)?
Hassio / HassOs is designed to be very small. On a Raspberry Pi you can install Raspian and install hassio on that. You would then have the desktop for your hdmi.
You basically follow the Linux install instructions, except you need to tell the hassio installer your machine type.
I am currently running hassio on Raspian Lite on by RPi.
I donāt need whole raspbian desktop. I just need chrome browser to start/stop some web page on it when I need to show some information from hass on my hdmi display. Because of that I wanna develop hass.io addon on hassos rpi image.
I look in addon developing documentation and I didnāt find right key to open x display on addon start.
I know that can be done with docker look that yt video and jess github link.
It must be possible with hass.io addon because they are docker containers.
Youāll need to look carefully at the structure of hassio addons and develop it.
You perhaps though kinda misunderstand the concept - a network attached device can simply use a web browser on another computer. If you want to deal direct with hassio, use ssh.
I know that, but I think this will be good enhancement for HA.
I seek a way to show HA dashboard or some web page on touch monitor connected directly to hdmi port of hassos host (in my case raspberry pi 3 SCB).
If I accomplished that, then I can automate start/stop of multiple docker container with different stuff to show. (dashboard, clock, photo frame, push notification, media player, ā¦).
Donāt use hassio then. If you are running a pi, use hassbian.
Why not? Where is limitation of hassio?
It is just not designed to run X. Whereas with hassbian you can just use apt-get.
Yes but far easier to use apt-get.
If you want to go the hard way, by all means do so, no doubt your work will prove useful to someone
There would not be enough demand for the developers to include it in HassOS.
They might be interested in accepting your code submission if you get it working, though
Shame. I already made addon for KODI with GUI. Addon is in early stage but works great.
If someone wanna try here is LINK
I have exactly the same need - to connect the touchscreen to the assos without a docker, but my 3-day search has not led to anything yet:
Stop tilting at windmills. HassOS is designed to be an appliance without an attached screen (except the occasional need for a commandline terminal, which is supported).
If you want to attach a screen for GUI purposes, go for another install method.
No windmills hereā¦
I wrote a HA addon that bundles X window system, Openbox window manager and Luakit browser to launch (and login to) HA dashboard.
Itās all very simple and lightweight ā and at least on a RPi5, it doesnāt at all load down the system. And itās quite fast since it doesnāt need to send data over your LAN.
Itās fully functioning though I continue to work on refining it so it is a work in progress.

As an aside, not sure why so many people have been ānegativeā about this use case ā it seems perfectly natural and even obvious to me to have a display attached to the actual device running HAOS ā even if just to check status. Plus, why spin up a whole new device when you can just access the display directly on the HAOS server.
