I got way in to Meshtastic when I was doing some group backwoods camping in national parks. Satellite was really the only other option at the time for long range, highly reliable communication and is so expensive! I got some t-beams and was super impressed by how well they worked. The interface at the time was very clunky and the software was in its infancy. In practice the devices were only usable in the context of showing their GPS location/distance from each other because the iOS support was specifically non-existent. That said I wanted them just to make sure if someone was gone for a long time, you’d know if they were okay by proxy of them moving and be able to find them if needed. It worked for that as a bare device.

The software has come a long way and I’ve been really impressed even though I haven’t been in a situation to take advantage of it again. I’ve got one of these on order though because it just tickles me.
