Ya.... They're doing something, but...
I'm not that impressed, really.
Water companies have been able to read meters from curbside, for years.. I could tell if my sprinkling systems, in several historic buildings armed, 18 years ago.. I'm not sure this device is that needed, by a homeowner..
My neighbor goes to Florida, on Oct. 1st.. Imagine him sitting in his cabana Dec.15th, and learning his waterline froze... It will take him 6-8 hours to get assistance, and, I dare say, after 15 minutes, damage would be extensive!
Water quality might be of interest.. Could be put into soft water monitor though.
Just thinking...
