I started reading about Meshtastic yesterday, and got an urge to set up a node even if (according to some maps) no one is near me. But then I started wondering, if I could reach another node, what could I do with that connection? What is it used for? Is it more about technically being able to send messages without an ISP. Do people use this for any real application?
It's basically a local chat program. Think of it like signal or text messaging, but that only happens locally in your area, unless you enable MQTT, which connects it to the internet. But in my opinion, at least that kind of defeats the purpose, especially if you can reach other nodes locally. You could enable MQTT to add yourself to MeshMap.net if you wish. But that's an opt-in process. And so, if you're looking at MeshMap.net, you may see nobody in your area when there actually are people using it.
When I got a node, I learned there are actually quite a few more people in my area than meshmap suggests, because there is a state based MQTT server that most people in this area use. It also means I'm still chatting somewhat locally, but hitting a much wider net than a purely local radio could.
