![]() ![]() Features of the app include: Easy to understand device status. Then program it either via a RPi or laptop/tablet. OpenSprinkler is an open-source Internet web-based sprinkler timer / controller built upon the Arduino platform. I separated out the front and back pieces of the case for easier printing. Also talk to a thermostat either a traditional 240V one or cleverer. OpenSprinkler controller case for the newest versions of the OpenSprinkler open source web based irrigation controller at This is an STL version of their xt file (included in the download section). OpenSprinkler Pi (OSPi) is an open-source sprinkler / irrigation extension board for Raspberry Pi (RPi). ![]() The kit doesnt come with a 24V transformer. That can hold a schedule, RTC and some relays. The firmware is completely open source Arduino code, and is hosted on github. Presumably the best solution for heating control, like this lawn waterer, is to have a low power controller, such as an ATmega, and some custom electronics+ relays. This causes the poor relays to thrash, which in turn makes them sicker. You can choose between AC-powered, DC-powered, or Latch version. The current version is OS 3.2, with built-in WiFi (based on ESP8266) and OLED display. So their repair is mostly replacing the relays (dead cheap).īecause of the logic states required to run a combie sick relays cause all sorts of problems cos a relay can contact, the board’s happy to switch the next device, and then earlier relay changes its mind so forcing the controller to backtrack. OpenSprinkler is an open-source, web-based smart sprinkler controller for lawn and plant watering, drip irrigation, farm irrigation, hydroponics etc. The 240V relays on the edges get trashed. What happens is that the extra-low voltage electronics lasts for ever. There’s a company that sells refurbed boards for a fraction of the price of a new one. A DIY Sprinkler Controller Using An ESP8266 2 Comments by: Jenny List There is something strangely amusing about the idea of a sprinkler system relying on a cloud. Marginally OT, but the circuit board for a combie boiler wear out after a few years. ![]()
