Ships with US/CA/MX Plug (110–120VAC outlets) ONLY. We do NOT include international adapters for the OpenSprinkler. If you need a regional adapter, you can acquire one from theofficial EU/AUS OpenSprinkler distributors here. We are NOT responsible for issues caused by faulty wiring/power supply.
Get full control of your irrigation. The Pulse Hub + OpenSprinkler integration allows you to create automated and scheduled watering events using the data from connected Hub-Ready Sensor(s).
Includes:
1x 24VAC/500mA USA (Type A) power transformer (suitable for max 2 zones simultaneous)
You will need a solenoid valve & diaphragm pump to get this running.
OpenSprinkler is an open-source, web-based smart sprinkler controller for lawn and plant watering, drip irrigation, farm irrigation, hydroponics, etc. It supports a variety of solenoid valves (24VAC, Latch, DC, motorized ball valve, etc.). Both versions offered here are AC-powered, look the same from the outside (same enclosure and ports), and work with the same Zone Expander, Sensor Expander, and W5500 wired Ethernet module.
Which version should I choose?
OpenSprinkler 4.0 – The next generation, built on the ESP32-C6. It adds a faster processor with more memory, WiFi 6 (2.4GHz, WPA3), stronger security, four sensor ports that can each be set as digital or analog (0–3.3V), a USB-C port for firmware recovery/debugging, and radio hardware ready for Matter/Thread/Zigbee (firmware support planned for future releases).
Take a look at theFAQs for common questions.
The 24VAC/500mA transformer that we sell is NOT suitable to run more than 2 valves at the same time (i.e. concurrent/simultaneous zones). If you need to run more valves at the same time, please find a transformer with a larger current rating.
