HIL Tennis have replaced our old Hunter SRC sprinkler controller with Opensprinkler PI. The new controller is now in charge of running a total of 24 valves on 4 outdoor Tennis Courts in Hamar Park, Norway. The upgrade has been a major improvement. Previously we had to manually adjust watering times and also had to shut down the system if there was a chance it would rain. The replacement of the controller was super-easy, and also the programming. A huge bonus is that we also use the IFTTT integration to log all events to a Google Calendar so that the people responsible for maintaining the Tennis Courts can see for themselves the logs from Opensprinkler without having to log into the system.
