⚙️ Script Activation:
The script is active by default, as indicated by active = true.
⏰ Trigger:
The script runs every hour, as specified by the timer:
timer = { 'every 1 hours' }.
📝 Logging:
Uses the logging level domoticz.LOG_INFO, with entries marked by "AWTRIX3_BATTERY" for easy identification.
🚀 Execution:
When triggered, the script performs the following actions:
🔍 Condition Check:
- Filters devices with a battery level below 20%.
- Ignores devices without a battery attribute or those with invalid battery readings.
🔄 Action:
- Sends notifications for devices with low battery levels:
- Battery < 20%: Uses a specific icon (ICON_BATTERY_20) and sends a warning.
- Battery < 10%: Uses a critical icon (ICON_BATTERY_10) and sends a critical warning.
- Formats the notification as a JSON payload containing the device name and icon.
- Sends the payload to the "AWTRIX3 - Send Notification" device:
- ✅ If the AWTRIX3 device is found: Sends the notification.
- 🛑 If the AWTRIX3 device is not found: Logs an error.
