Flow Details
π Flow:
-
Trigger:
- Runs every 1 minute to check device statuses.
-
Condition:
- Filters devices that:
- Have not updated within the threshold (7200 minutes by default).
- Are not in the whitelist of excluded devices.
- Filters devices that:
-
Actions:
β For each dead device:- Logs the device name and time since the last update.
- Creates a JSON payload with a notification message and a specified icon (ID: 1059).
- Sends the notification to AWTRIX3 using the "AWTRIX3 - Send Notification" device.
-
Whitelist:
- A predefined list of devices (e.g., "AWTRIX3 - Send Custom App", "Voordeur - Beweging") that are excluded from monitoring to avoid unnecessary alerts.
-
Logging:
- Provides detailed logs for each dead device, the notification payload, and the AWTRIX3 sending process.
