hey there and welcome @Kirsa!
Looks like you got some awesome stuff in the works (I need to
ESP32 now... ow wow that's some awesome low-power wireless stuff).
Looking forward to see more posts about your contraptions :).
@Zelf posted some really nice links already, but this "NODE Vol 01" zine-book post by @mike might be of interest to you. I don't know if you receive their post yet so you should be able to find all resources and the (downloadable) book itself over here https://n-o-d-e.net/zine/. It covers a lot of tacky stuff on off-grid networks, etc.
