| RF (group) | Shure connections; battery ≤1 bar red, 2 bars amber; RF interference (only while that transmitter is on); PSM RF muted; each receiver pinged every 3 s ("AXIENT 1 NO PING" in about 6–9 s; Companion's Shure modules take 18–27 s to notice). The address is the one set on its Companion connection, read from Companion's settings every minute, so changing it there is enough; `"host"` in `config.json` is only the fallback. |
A problem has to last 3 seconds before it shows, so one bad reading doesn't trigger an alarm. Recovery shows immediately.
