LED Config

Controls the four LEDs on the device. Each LED can be set to ON, OFF, blink, flash, or pulse for a precise duration.

Key path: devcfg.led

{
  "devcfg": {
    "led": {
      "led0": "P100",
      "led1": "S0",
      "led2": "F0",
      "led3": "B0"
    }
  }
}

Note For one-shot LED commands, use the corresponding actions: {"a":"led0","p":"P100"} — see LED actions. The devcfg.led keys set the LED’s state/default directly; prefer the action form for one-off commands to keep behaviour consistent with the rest of the app/actions API.
