For instance an RPI that just boots straight to a full screen browser with nothing else. I’ve used Magic Mirror but I want to switch to a web based dashboard instead.
Edit to clarify: Specifically talking about a cheap computer and monitor setup, not a tablet and touch controls won’t matter.
At work, we use PiSignage for a large overhead screen. It’s based on Debian and uses a fullscreen Firefox running in the labwc compositor. The developer advertises a management server (cloud or self-hosted) to manage multiple connected devices, but it’s completely optional (superfluous in my opinion) and the standalone web UI is perfectly usable.
