Minimal field JSON:

  "type": "alarm_control_panel",
  "name": "Alarm control panel"
}

Full field JSON:

{
  "id": "alarm_control_panel",
  "type": "alarm_control_panel",
  "name": "Alarm control panel",
  "default": "disarmed",
  "controls": [
    {
      "key": "",
      "type": "action",
      "label": "ui_124",
      "command": "",
      "payload": "ARM_HOME"
    },
    {
      "key": "",
      "type": "action",
      "label": "ui_125",
      "command": "",
      "payload": "ARM_AWAY"
    },
    {
      "key": "",
      "type": "action",
      "label": "ui_126",
      "command": "",
      "payload": "ARM_NIGHT"
    },

  "ha": {
    "command_topic": "$command",

Properties in the full example:

Property	Required?	Meaning / default
id	Required	Stable application key; unique across registered pages.
type	Required	Enabled field type.
name	Required title¹	Display title; may be replaced by a nonempty names object.
default	Optional	Omit to use the built-in initial value.
controls	Optional	Omit to use the preset controls; supplying an array replaces them.
ha	Optional	Omit to use automatic HA discovery; supplied properties override defaults.

¹ name can be replaced by names. Other shared optional properties are listed in the catalogue.

The control provides Arm home, Arm away, Arm night, Disarm and Trigger buttons. Its default state is "disarmed"; commands are ARM_HOME, ARM_AWAY, ARM_NIGHT, DISARM and TRIGGER on the base topic. Matching reported states are armed_home, armed_away, armed_night, disarmed and triggered. The preset does not require a code and does not offer a PIN-entry field. Changing HA code-related properties alone does not implement code handling in the portal or firmware. The raw state string is hidden; selected buttons reflect reported state.

Read and update values from C++

These examples use the field ID from the JSON above and an existing ArdPortal portal. Run them after page registration has finished and portal.portalAndAppConfigReady() is true. Call portal.loop() frequently. Register callbacks once in setup(); do not repeat setters on every loop iteration.

Set the value with automatic ArdFS persistence

Set "persist": true on this field in its page JSON. It is optional for editable fields whose preset already persists settings, but required to override a RAM-only preset such as a sensor. Calling setAppConfigValue() sets the control value and ArdPortal automatically saves AppConfig through its integrated ArdFS storage. Do not create an ArdFS object or call a separate write/flush method. The automatic save is coalesced and advanced by subsequent portal.loop() calls.

// Use this path when the value is a setting that should survive restart.
ArdJSON::JSONVar next = "disarmed";
if (!next.isValid() || !portal.setAppConfigValue("alarm_control_panel", next)) {
  Serial.println("Setting rejected or storage temporarily unavailable");
}

true from the setter means acceptance, not a completed flash write. Configure this callback once to observe the result:

portal.onPortalAndAppConfigSaved([](bool ok, const String& error) {
  if (!ok) Serial.println(error);
});

Update only RAM

// Use this alternative for live readings/status; never writes ArdFS.
ArdJSON::JSONVar next = "disarmed";
if (!next.isValid() || !portal.setAppConfigStateValue("alarm_control_panel", next, false)) {
  Serial.println("Runtime value rejected");
}

The third argument false avoids queuing an immediate MQTT publication. Use true or omit it to queue changed state. RAM updates work regardless of persist. Alternatively, with "persist": false, setAppConfigValue() also follows the RAM-only path.

Read the current value

const ArdJSON::JSONVar current = portal.getAppConfigValue("alarm_control_panel");
if (!current.isUndefined() && current.isValid()) {
  Serial.println(ArdJSON::JSON.stringify(current));
}

The getter returns the effective field value: RAM override first, then saved AppConfig, then the definition default. A RAM-only update is lost on restart; the saved value/default becomes effective again. Choose the persistent or RAM path for a given value. A RAM override can mask a later persistent change for the same ID; there is no API to clear just that override. Prefer separate setting and telemetry IDs when both are needed.
