I am currently running HA OS on unraid and have 2x 15.6" touchscreens with RaspberryOS desktop used for displaying and control the entities.
I would like to install HA OS on one of the touchscreen Pis instead of unRAID so I can turn of the server and still have control of my home.
I know how to install HA OS on a Pi (had it running in the past).
I want one Pi to run HA OS and a web browser “vieweing” itself (127.0.0.1) and the other Pi will still run just a web browser with RaspberryOS desktop pointing to the 1st one.
My question is how can I install HA OS and a web browser on the same Pi to be used with the touchscreen?
