Using the MeshScope application from Lemuridae Labs, you can view the current status of the global Meshtastic network, viewing nearby nodes and looking at other activity. This app provides a quick viewing experience integrated to the MeshScope web site.
Although this will show the Meshtastic network, it does not require a local mesh radio and uses an internet connection to retrieve the mesh network information. This also means that the app will not be able to show any mesh radios not reporting to the global Meshtastic MQTT network.
For information on Meshtastic radios and networks, visit https://meshtastic.org/ for details.
