I managed to jailbreak my SeeStar and install some SSH keys on it and poked around looking at things. Then I stopped. I just use it like a normal person and use the app plus the incredible https://github.com/s...rld/seestar_run Python to do mosaics and stuff. You really don't gain anything other than a sense of accomplishment by cracking into it. It's good at what it does, so I've decided to let it be what it is.
I assume that software upgrades in the future will add things like internal mosaic capabilities, perhaps scheduling, or at least target selection and imaging times.
You could shoehorn dropbox or tailscale on there to change how you use it, if you're feeling saucy. Maybe a little trashcan dome for it with a remote controller..
