JK buy yourself a raspberry pi, or a low power pc (second hand dell wise), or even just an existing computer that you can turn on when you need to do something.
If you go for the Pi option, install home assistant and GivTCP as per speak to the geek YouTube videos.
You can then monitor and control the system without needing a broadband connection, as long as WiFi is up, or wired ethernet ideally (especially at the Pi end), you'll be fine.
Or if going for a computer, probably looking at GivTCP in docker, but there are other options too.
That's how I started off, GivTCP in docker and just ran commands via a web browser to tell it to fetch battery details or other data. I think some of this is covered on the unofficial wiki - there's a sticky post somewhere about that (or search for wiki).
I've since upgraded to the Pi with an SSD connected and home assistant running. It's great! It can be a little addictive though. 😁
