“Replace your sprinkler controller with a simple and inexpensive Raspberry Pi, web page-based system.
Story
Replace the old old sprinkler controller in your garage with a web page-based Raspberry Pi controller.
In this project, I took a new Raspberry Pi, installed OpenSprinkler on it, and used a simple relay board to trigger my home sprinkler system. To schedule my sprinkler system, I access a web page served by the Raspberry Pi on my home network. The web page is accessible only on my home WiFi network.”
