Ok I’m getting lost here, any tutorials/videos that demonstrate how to operate the simulator?
Don't worry too much about it. EKOS has somewhat of a learning curve (I don't think much more than any other platform.) And you'll grow into it. Basically, most of the "official" tutorials on Youtube use the simulator. But I'll try to create a short video that demonstrates it in more detail.
I've been playing with the idea to start an EKOS channel on Youtube perhaps a good way to get my feet wet.
Also, we're getting a little off topic. But I think most posts demonstrate that there are a lot of viable options. And that a Astroberry/Stellarmate setup can cater to many different situations. Be it directly connected through wifi hotspot or crosscable or over the network wireless or cabled.
If you are taking your setup on the road it might be worth looking into extra storage for yuor PI. I don't have any experience with that but I hear people mentioning SSD's a lot.
Personally, I would investigate a fast thumbdrive that could plug into your PI. But again, no experience.
