Every drop meters WM-1000 not reliable?

I bought this wireless flow meter with hopes of keeping track of leaks and staying ontop of my usage. Installed less than a week ago and all I can say is that I’m extremely dissatisfied and disappointed with the reliability. I’m always getting “no flow” alerts or “leak detected”. My receiver is 40 ft away in a direct line of sight with nothing in the way except a piece of 26 gauge metal.

They really should allow you to tweak the settings on the calibration and set different ranges. I’ve recalibrated 20 times to try and find a middle ground. It would also be nice if it allowed real time monitoring of the GPM when the sprinklers are going besides just while calibrating.
