How to use
Place the Gosund ST19 sensor flat on the floor in the location most at risk of flooding, using the 1 m cable to position the detection probe where water would first appear. Insert two AAA batteries and pair the sensor with a ZigBee hub or add it via the Gosund or Tuya mobile app following the app pairing instructions. The red LED indicates device status; when water is detected the sensor triggers an alert to the hub and sends a notification to the connected app.
Usage recommendations
Install the sensor on a level surface where water is likely to collect, avoid placing it on uneven or elevated surfaces, and keep it within the ZigBee network range of your hub. Replace batteries when the low-battery alarm appears and test the device periodically to ensure proper operation. Do not expose the sensor to temperatures or humidity levels outside the specified ranges.
