Gateway message format

M5Stack Station → app, USB serial or Wi-Fi

Each S31 plug broadcasts a heartbeat every 0.4 s. The Station watches for silence and prints one line per event, over USB at 115200 baud and over its own Wi-Fi network (ws://192.168.4.1:81). The demo sends the same lines.

N07,HB,V=121.4,RSSI=-61
N07,LOST,V=121.2
N07,RESTORED,V=120.9
N12,NEW,MAC=48:3F:DA:1C:22:9E
N12,BTN
N35,HB,V=120.4,VIA=N12
N12,HB,V=121.0,RSSI=-55,RELAY=1
N35,NOLINK,VIA=N12

N07: Node number. The Station assigns it the first time it hears a plug and remembers it by MAC address.
HB: Status every ~10 s per plug, with line voltage from the S31's meter chip
LOST: No heartbeat for 2 s: the plug lost power
RESTORED: Heartbeat is back (the plug rebooted)
NEW: First time this plug was seen. Write the number on its label.
BTN: Someone pressed the plug's button. The app selects that node so you can place it.
RELAY=1: This plug is in relay mode (hold its button 5 s). It re-sends far plugs' heartbeats to the Station.
VIA=N12: The Station only hears this plug through relay N12
NOLINK: The relay carrying this plug went silent, so the plug can't be heard. Not a breaker result: it may still have power.
#…: Gateway status and results from mapping on the Station's own screen
