How to use
Install the Gosund ST20 on a wall or corner at the recommended height for optimal coverage, using the included mount or adhesive. Insert two AA batteries or connect a Micro USB supply (DC 5V/1A). Add the device to a Zigbee-compatible hub via the Gosund/Tuya Zigbee integration or the Gosund mobile app, then configure detection sensitivity, notification settings and any automation routines (for lights, alarms or cameras) in the app. Test the sensor after installation to confirm detection area and notifications.
Usage recommendations
Place the sensor where it has an unobstructed view of the monitored area and avoid pointing it directly at heat sources or windows to reduce false triggers. Regularly check battery level in the app and use alkaline AA batteries for stable operation. For reliable connectivity, ensure the Zigbee hub is within range and consider adding Zigbee repeaters if needed.
