Comment on This Tiny Radio Lets Me Send Texts Without Wi-Fi or Cell Service

It is channel-based, using Pre-Shared Keys (PSK).
There is a public line where you can message pretty much everyone with the blank PSK.

If I wanted to transmit, for example, temperature and humidity from a sensor once every 5 minutes, would the network be willing to carry my signals?

SENSOR is one of the defined device roles. And whether for personal automation or public information, it is a reasonable use case for the network.

Everything I learn about this project is so cool. I can’t go through the docs right now, but I’m assuming it can prioritize things like emergency communication over sensor data.
There’s no public nodes in a 200+ km radius around me on that site someone linked, so something tells me I’ll have to do a lot of guerilla solar panel installation if I want to anonymously set up something.
I’ve thought about it on and off over the past two years, more of a private network for family and friends than anything, for emergencies and so on. The real, big problem is that I could be accused of espionage and thrown into jail forever if I do this. So I don’t think I’ll see anyone putting any nodes up for the foreseeable future.
