I am using these NC sensors with reef-pi / Robotank.

I have them setup properly and they work. My rodi tank one works to notify me when it needs refilling. However, the ones actually controlling an ATO / high sump / low sump have issues due to the nature of a sump vs clean rodi tank.
If my sump has any film on it (even a nearly spotless side wall) it does not detect when water is missing. I tested by pulling out cups of water to drop the level of the sump and it was about 2 inches lower than the edge of the sensor and still thought there was water present. The second I wiped the inside of the sump with a paper towel to clean the film, it triggered as missing water.
Is this a common theme with all NC sensors or did I just buy crappy ones? I am ordering regular old float switches to setup as those are tried and true with all the homemade ATO's ive made.
