OpenSprinkler – Which version is right for me?
OpenSprinkler is available in different hardware variants. This table will help you choose the right version for your needs.
🍓 Note on OSPi variants: The OpenSprinkler Pi versions are Expansion boards for the Raspberry Pi – a Raspberry Pi (Zero W to RPi 4). not included and must be purchased separately. Installation and configuration requires Basic knowledge of Linux and Raspberry Pi. As a complete Linux system, OSPi offers maximum flexibility, but is significantly more complex to set up and maintain than a finished OpenSprinkler controller.
