- Disarm: All sensors are disarmed.
You can arm/disarm using the control panel, remote control, Smart Life App, or voice commands via Alexa.

- System Auto-Disarms: Check the 'Timed Arm/Disarm' settings in the control panel and the Smart Life App to ensure no schedules are configured for automatic disarming.
- Excessive App Alerts: Review notification settings within the Smart Life App. You may be able to customize which types of alerts trigger push notifications.
- Alexa Integration Issues: Verify that the 'Smart Life' skill is enabled and accounts are correctly linked. Ensure your Alexa device and the alarm system are on the same network. Check the Alexa app for specific error messages or device status.
