Woah, woah, woah, any more about this? The wireless sensor has to be installed past the backflow device making it useless for whole home usage monitoring. You mean to tell me if I pick up a $100 wired meter and run this into my R3 I could, in theory, monitor whole home usage?
I get that Rachio is geared towards looking at my irrigation usage, but I also send the usage data to smartthings. Based on this info I might be able to use smartthings to let me know when prolonged high usage has been detected.
