• Device status and battery/standby reporting to help manage uptime and charging alerts
• User interaction events (button presses, app usage) available as status markers in Green-Gps where supported
• Custom alerts and notifications for low battery, network loss, and device offline state
• Green-Gps support for additional inputs (e.g., ignition/immobilizer or BLE sensors) applies to compatible devices; the D55B-A9C integrates where equivalent data is provided
