I built a sprinkler system that has 14 zones. Using raspberry pi and relays. It has a web interface and can run on schedule or manually. Worked out to be better than a kickstarter I backed, lono, that turned out to be dud and the company went under.

I plan to open source it. have to clean up the code. Built with python flask, GPIO and a small custom PCB that interfaces pi with the off the shelf relay boards.

Todo - flutter app - 3D printable enclosure to package the entire set. - basic logo etc.

Me too! Was astounded by the price of a standard solution and said to myself, "I can do that cheaper [ assuming my time is worth less than minimum wage.]" Still works, 7 years after install.
