i have installed Hass.io with HassOS on my Pi3 and a touch screen is connected to my Pi3 via HDMI. Is it possible for HassOS to automatically start a GUI that is then displayed directly on the touch screen without having to access from another device via the browser? So I want HassOS not to show me the shell, but to start a GUI where i can control me lights, heating and so on.
I think Hassbian uses Raspian Lite which has no GUI.
You would need to install full Raspian and then you can install Hassio or a different Home Assistant installation.
It would likely take some scripting for it to work automatically.
I am assuming the touch screen is capable of displaying a desktop environment.
That is another option. Since they mentioned HassOS I figured they may want Hassio.
Actually with the added CPU load on a Pi for a desktop environment, I would personally look for a different solution. I realize there are many choices in desktops but some people already say their Pi is under powered.
