The Hydrosys plant nursery irrigation system is up and running. I have set up 20 different irrigation lines but will probably add a couple more soon. It is a stand alone system powered by a battery connected to a solar panel. Wiring is a bit messy. The switches are connected so that individual water lines can be manually switched if need be. It is connected to a wifi network and uses the weather API to control watering period. And I must say, Angelo's work on Hydrosys and the fact that he makes it freely available on the internet is simply amazing. The nursery where I installed the Hydrosys system in Far north Queensland, Australia, is owned by my friend of Italian heritage. He was so happy when I told him that the developer of the software is from Italy. There is a lot of positive Karma floating around. Thanks again Angelo from both me and Phillipo!
