How it works →The neighbour lists and coverage scores on this page come from observers feeding the regional analyzer. Set yours up with:
In the observer’s console (USB serial or the web flasher’s terminal), one line at a time:
set mqtt.iata SJC
MQTT endpoint not published yet - ask in this mesh’s community for the server and audience, and a coordinator can add it here.

Everything on this page is community-maintained - every listing links to who added it and what changed. Nets and the California feed live in the rail; the four tiles above are the state’s official groups.
