I didn't see calsense either. Walked the floor for almost five hours, spoke to some vendors, noticed moisture sensors are being pushed everywhere.
Saw some interesting two-wire controllers but the price of the system may be a bit more than I can get my clients to use. Bunch of curmudgeonly builders who still lament the day aluminum beer cans were introduced.
Spoke with the water sense people, that looks a bit interesting.
Nice Try = You Suck Spelled Differently
