I have a Tank Level sensor. Yesterday the sensor was transmitting level at 825. Today, I am getting level readings of 9999. The physical sensor is only 33 inches above the floor (for testing purposes). Any idea why it would all the sudden it is reading so high? I rebooted the unit and am still getting 9999 values for level.
sensors sends 9999 is it can not detect any object or having trouble locking.
