> Is this using WiFi only?

Currently, our software stack only supports WiFi and Ethernet at the data link layer, but that’s mainly because these are easy to set up with linux/batman, not because of an architectural problem.

Other technologies are not only possible but also on our roadmap. Just recently, for example, I’ve been taking a first look into getting LoRa working with hyveOS, but this would probably be a more long-term project.
