@Chelle_belle

Check if you can see the sensor on hub's connected device list.
Rule out the possibility of loose or poor battery connections: take off the back cover and press the battery with your hand to check if the LED light comes on.

When you reinstall the battery, does the same thing happen -- flash briefly then turn off?
