The goal is to be able to manage everything from one place.

Hardware:

Asus Linux laptop (x1504za) and HP prodesk 600 (Manjaro Linux)

Samsung S24FE with Termux

LilyGo T-Watch S3

LilyGo T-Deck Pro

Raspberry Pico 2W (3 of them so far)

Odroid Go Ultra (just for Tetris, a remote control one day)

Acer Tab 10 (not used much yet)

Software:

Perl with Mojolicious

Chromium on PCs

Chrome on Android

Sometimes I use Firefox

I'm pretty sure this project will run on any hardware. When I started writing it I was using an HP/Compaq with a Core2Duo.
