    Picked one of these up, installed it and everything just worked as expected. Great product, pick one up, you won’t be disappointed

    This is an excellent product! I work in a large multi-greenhouse facility that used to use very outdated and cumbersome system to control the irrigation. I ordered an OpenSprinkler to see if they would work in my environment and they continue to exceed our expectations. I will soon have 5 working controllers on site and they will all be easily accessible thanks to the great technical support from Ray and Salbahra. I highly recommend OpenSprinkler whether you’re watering your lawn or golf course, or growing cut flowers or tree seedlings.

    Great controller, I was looking for an alternate for the ‘dumb’ controllers out there after having a few fail for me and I couldn’t be happier. Easy install, great service and fast shipping (even to New Zealand. Thanks!

    This is a really awesome device. I was concerned i would get it only to find out i needed an electrical engineering degree to get it working. The fact is I wired it up, plugged it in and within minutes it was up and running. I’ve even managed to get it working over the internet, via port forwarding. The hardware boots up fast, the app is bare bones with no flashy icons, but it responds quickly and it just works. I have used the app on Windows, ipods, iphones, and even a Blackberry 10 device. Two thumbs up!

    Really enjoying the OpenSprinkler system! So glad to have an open, mobile phone controlled system. I’d suggest finding a well fitting external enclosure (aka, the box that holds the open sprinkler, wires, space for mini router, etc) and sell it to (cheap plastic box that mounts on the wall). I was able to reuse my old sprinkler enclosure, but if you sold one that had a place for the open sprinkler box, expansion boards, etc) I’d have bought that too. 🙂
