I chose to go with a server / client configuration as I wanted multiple displays around the house with the same information.

Server is an RPi3+ and clients are RPi Zero 2W’s.

I use Dietpi as it has the least amount of overhead for both system. The server was easy to set up on Dietpi, same as a normal setup the RPi OS.

For the client, I can provide a bash script that configures the client. It uses a minimal set of installation packages (under Trixie) in Kiosk mode (no window manager).

I’ve also set cron jobs to turn the display on/off during night. I also have aliases setup to control the client.

All the best,
W.
