Hello, I would like to know if it is possible to run HA OS on my Raspberry Pi 4 connected directly to the Raspberry Touch Display, run a kiosk there and control my HA, or do I need a second Raspberry… one for HA OS and one for the display? Thank you.
Hello,
Install HA in a docker container and access it via a web browser in the host operating system.
I don’t know how experience will be running both on a PI4, probably depends on RPi model, at least 4GB RAM, I am just guessing the RAM needed.
My RPi 4 model B has 8 RAM so it should be okey but my display currently show Home Assistant command line interface and I do not know how to open browser or do anything 
Hey,
You are running HA os so you see the CLI.
This way it won’t be feasible as far as I know.
In this case you need another machine to access the web interface, just navigate to ip_adress_ha:8123 as showed on the CLI.
The way I am suggesting is more complex:
you should install an OS on your rasperry
then install docker
run docker container for HA.
On RPi you can even install an os without desktop and then run a web browser from the os, but maybe for the moment keep it simple and install raspbian with desktop.
If you want to save resources and you will use the RPi only to graphically access HA you can install raspbian lite and then run a browser automatically at startup showing the HA interface.
Is a bit complex, maybe just make your experience with HAOS and then try the other way.
There are many tutorial like: Installing Home Assistant using Docker Compose - Pi My Life Up
Installation - Home Assistant See docker.
you may want to pay attention and understand the volume mapping for docker containers and you may encounter issues connecting to the same ip, from the host os to the ha container. I am not sure of this last concern I have never tried myself, maybe a project for saturday…
If you don’t mind try and see…
Hello again,
I remebered something and I have found it
