Alert Config

Controls what events trigger an alert, how the alert behaves once active, and how the device notifies the user.
The trigger and cancel parameters are one‑shot — set them to true to fire or cancel; the device resets them to false immediately.

enabled

Master switch for the alert system. When false, no alert triggers (button, sensor, or backend) will activate the alert state.

Configuration variables

• Type: boolean
• Default: true

{ "devcfg": { "alert": { "enabled": false } } }

cancelByReplace

If true, a new alert automatically cancels the current one.

Configuration variables

• Type: boolean
• Default: true

{ "devcfg": { "alert": { "cancelByReplace": false } } }

onHomeDClk

Triggers an alert on a double‑click of the Home button.

Configuration variables

• Type: boolean
• Default: true

{ "devcfg": { "alert": { "onHomeDClk": false } } }

cancelByHome

If true, pressing the Home button cancels the current alert.

Configuration variables

• Type: boolean
• Default: true

{ "devcfg": { "alert": { "cancelByHome": false } } }

onDuress

Triggers an alert when the Duress button is pressed.

Configuration variables

• Type: boolean
• Default: true

{ "devcfg": { "alert": { "onDuress": false } } }

onFall

Triggers an alert when a fall is detected by the accelerometer.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onFall": true } } }

onShock

Triggers an alert when a shock is detected by the accelerometer.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onShock": true } } }

onDTap

Triggers an alert on a double‑tap gesture.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onDTap": true } } }

onProne

Triggers an alert when the device remains in a prone position (face‑up or face‑down) for proneTimeSecs seconds.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onProne": true } } }

onRed

Triggers an alert on a long press of the Red button.
Long‑press duration is 3 seconds (2 seconds in earlier firmware).

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onRed": true } } }

onBlue

Triggers an alert on a long press of the Blue button.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onBlue": true } } }

onBlueRed

Triggers an alert when Blue and Red are pressed together.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onBlueRed": true } } }

onDuressRed

Triggers an alert when Duress and Red are pressed together.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onDuressRed": true } } }

onDuressBlue

Triggers an alert when Duress and Blue are pressed together.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onDuressBlue": true } } }

onDuressGrey

Triggers an alert when Duress and Grey are pressed together.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onDuressGrey": true } } }

onDuressBlueRed

Triggers an alert when Duress, Blue, and Red are all pressed together.

Configuration variables

• Type: boolean
• Default: false

{ "devcfg": { "alert": { "onDuressBlueRed": true } } }

proneTimeSecs

How many seconds the device must remain prone before onProne triggers an alert.

Configuration variables

• Type: integer
• Default: 10

{ "devcfg": { "alert": { "proneTimeSecs": 20 } } }

showFlash

If true, the LED(s) flash when an alert is active.

Configuration variables

• Type: boolean
• Default: true

{ "devcfg": { "alert": { "showFlash": false } } }

showVibr

If true, the vibration motor runs when an alert is active.

Configuration variables

• Type: boolean
• Default: true

{ "devcfg": { "alert": { "showVibr": false } } }

showSound

If true, the speaker plays the alert tone when an alert is active.

Configuration variables

• Type: boolean
• Default: true

{ "devcfg": { "alert": { "showSound": false } } }

showMsg

If true, a visual message is shown on the screen during an alert.

Configuration variables

• Type: boolean

{ "devcfg": { "alert": { "showMsg": false } } }

onMsgSound

Sound to play when a new alert message arrives (from backend).

Configuration variables

• Type: string (audio code)
• Default: "AT1"

{ "devcfg": { "alert": { "onMsgSound": "AT2" } } }

onMsgVibr

Vibration pattern to play when a new alert message arrives.

Configuration variables

• Type: string (vibr song)
• Default: "V10"

{ "devcfg": { "alert": { "onMsgVibr": "V20S10V20" } } }

onMsgFlash

If true, the LED flashes when a new alert message arrives.

Configuration variables

• Type: boolean
• Default: true

{ "devcfg": { "alert": { "onMsgFlash": false } } }

cancel

Set to true to cancel the current alert from the backend.
The device resets this flag after processing.

Configuration variables

• Type: boolean
• Default: false
• One-shot: yes

{ "devcfg": { "alert": { "cancel": true } } }
