If you need to run more zones at the same time, please find a 24VAC …The application allows you to automatically detect and control your OpenSprinkler irrigation system(s). OpenSprinkler is an open-source Internet web …OpenSprinkler Pi (OSPi) is an open-source sprinkler / irrigation extension board for Raspberry Pi (RPi). It is based on the design of OpenSprinkler, but its ‘brain’ is an RPi instead of an AVR microcontroller. The idea of OSPi first came when I noticed that many users were setting up RPi to work with OpenSprinkler.One thing you can check is the wire resistance. Use an online calculator to compute the wire resistance, such as this one: keep in mind that you need to input the round-trip distance. Typical sprinkler valves draw about 200 to 300mA holding current, and if the voltage drops below 18V AC they are unlikely to stay on.For OpenSprinkler 3.x only — one major step forward is the support of OpenThings Cloud (OTC) token, which allows remote access via the OTC cloud server.

Having bought my OpenSprinkler I first tried to connect it via WiFi by buying the successor of the recommended WiFi Router, a TP-LINK TL-WR802N. As the controller is located under the surface about 20m away from our house it didn't get a connection. So I thought about PowerLine and bought an AVM FRITZ!Powerline 510E Set Keymaster. 1. yes, it should work with OpenSprinkler. The output of this soil clik sensor is a relay which is a dry contact type. 2. no, this soil sensor is not a dry contact type, it requires an additional microcontroller to ‘interpret’ the result of the soil moisture value. It cannot be used directly with OpenSprinkler. Participant. I agree with Jim. Most of the people using a RPi are likely to tinker with their installation. I – for my part – put a 128×64 SSD1306 OLED display (standard I2C) between the Pi and the acrylic …Keymaster. OpenSprinkler is currently designed to work with 24V AC valves only. It’s probably quite difficult to power these valves with battery / solar panel.
