It-Gets-The-Hose-Again is a Raspberry Pi (compatible with A,B,A+,B+,2, and Zero) controlled Garden sprinkler system that can be controlled via a built in web UI or by HomeKit compatible Apps. This repo includes the source & installation instructions for controller software as well as schematics for the hardware components that need to be added to your Pi in order for the software to control sprinkler hardware.


The controller software is built on Node.js with React.js/Redux powering a web UI front end. The software allows a configurable watering schedule and uses OpenWeatherMap to save water by not watering if it is already raining. The controller software is also compatible with Apples HomeKit if you wish to control the sprinkler via HomeKit instead of via the web UI.

The web UI on mobile


The hardware consists of a small circuit to allow the Pi to control a 24vAC solenoid water valve such as this one, and a 3 LED status panel. DC water valves or valves using different voltages etc should also work with this control circuit, though this has not been tested.
