I just installed the new 2.0 version of the BlueSpray irrigation controller. On the positives, it does just about everything you can imagine: unlimited programs, unlimited schedules, interactive weather, rain sensor, modular expansion up to 64 stations, graphical drag & drop interface, Wifi & Ethernet connectivity. On the negatives, no Z-wave, and it's cloud-based.
Any one willing to build a wifi plug-in?
