Anyone know of a Good Water Sensor that will work with the Black? After my sump pump failing last night during a downpour, I’m itching to put an early detection system in place…
Finding your basement has 3 inches of water in it at midnight is not fun. 
I am also interested in answers to this need but for the opposite reason. My daughter is a marine biologist and has on occasion monitored experiments in tanks where you want to know if the water level is too low.
@Michael_OBrien_hardw for tank level I’ve seen pressure sensors used. I’ve also seen magnets in a foam float and a series of sensors inside a tube that the float, floats up and down on to indicate tank level.
Jason, you could use an extra float switch in your sump to sound the alarm before it overflows,
Might be a workable solution… I’m not sure though how much water there would need to be to get something like that to register.
