Considering the amount of tech and self hosting types that live in cities, it seems like it would be popular to have little mesh intranets all over the place, but I’m not aware of any.
I read about NYC Mesh a while back, and I wonder if there are other similar things already in widespread use that I just haven’t heard about.
Building a node can be done for under 20€ with a Heltec V3. Not the most power efficient, but not an issue if you’re running it from usb power anyway.
Also a note: the map doesn’t show all nodes, my node can see a lot more devices around me than are listed on the map. Maybe some issues with reporting or something (which is optional in the first place)
If you want a power efficient device with an enclosure, Seeed Studio make some decent stuff. I run a pair of Wio L1s (one on Meshtastic, the other on MeshCore), which cost around 40 € complete with antenna, battery, and enclosure.
Sure, more expensive than a bare V3 but more convenient for actually taking them somewhere.
How do those networks compare for you? I’ve considered both but in my area meshtastic seems to have a bigger community
