Make sure the bottom of your sensor is completely dry and that nothing conductive is touching the bottom of the sensor. Check the Ring app dashboard for a message that says "Water detected". Tap the message window to take action to dismiss or resolve the message.
Does not detect water
Make sure the line on the side of the device is aligned with the lock icon to ensure the cover is properly secured. In order for the sensor to be triggered, water has to be touching both contacts on the bottom of the device. Reposition your Flood & Freeze Sensor so it is on a flat surface where water would pool. Choose locations next to possible sources of flooding, but place it so it won't be accidentally moved.
