well I have to say after a year I have removed the sensors and given up on this system, when it worked it was good but this spring I could not get one of the sensors to pair with the app and the indoor led gauge never matched anything close to the app readings, the end came when I was removing a sensor to replace the battery and the rubber covering the sensor stuck to the tank and pulled the sensor and wire right out of the housing. It is a great idea and the phone apps is good the sensors need to be heavier duty and the spacers should be solid so when you tighten your tank holding bracket and the tank compresses the rubber spacer it and ends up crushing the sensor on the bottom of the tank. great idea just needs some improvement to make it worth the effort so for now I will go back to keeping an eye on my switch over to gauge my use. got to love gadgets some are great other not so much
