Then after wasting a bunch of time troubleshooting, I also determined that I needed to set each station Active State to ‘Low’, rather than the default of ‘High’. I set each of them to ‘GPIO’ type instead, and used the pin mapping chart to set the GPIO number accordingly. Each of the 8 default stations was set to Station Type ‘Standard’. After digging around in the OpenSprinkler interface, I found the screen for configuring each station (Gear icon by the station name->Advanced tab). The board is supposed to be directly addressable using the Pi’s GPIO pins, and I found a chart showing the pin mapping on the documentation page found earlier. OpenSprinkler Pi (OSPi) is an open-source sprinkler / irrigation extension board for the Raspberry Pi. The interface seemed pretty simple, but I was not able to get any of the board relays to engage when manually triggering the sprinkler zones.īack to the documentation. Everything went smoothly, and I was able to pull up the web interface. The board seems to be known as the WaveShare 15423 (UPC 614961953253) on some sites.Īfter flashing Raspbian Lite, I installed OpenSprinkler using the instructions on their site. The OSPi interval program available on the Raspberry Pi has an additional option as you mentioned, rp. A quick search turned up a similar board on Amazon, which led me to a wiki with more info and the promised documentation. That is the correct list for the OpenSprinkler. The no-name relay board was supposed to come with documentation and code examples, but alas the package contained only the board itself, and a small package of (not enough) mounting screws. So…I pulled out a spare RPi2 from storage, ordered up a cheap relay board made of pure Chinesium, and got to work. OpenSprinkler seems to be the best in the DIY irrigation game at this time, but their hardware prices are out of my range. Pulls updates from your OpenSprinkler firmware.Bonus points if you can spot the dead gecko…
