There could be a number of reasons why your SmartSense sensor is not pairing.
- Try pairing the device again while holding the orange sync button to try and force the app to detect the sensor.
- The SmartSense sensor could still be in factory mode. Press the orange sync button on the SmartSense sensor 6 times. This permanently disables Sleep Mode, which is the factory setting. After this, try pairing the SmartSense sensor again.
- Bluetooth and/or Location Services could be disabled on your device. Make sure Bluetooth and Location Services are turned on on your device and try pairing the SmartSense sensor again.
