![]() ![]() Knapp had the good sense of marking the wires that were actually being used with black electrical tape.įrom this point, it was fairly straightforward. When we got to Step 5 (“Wiring Sprinkler Valves”), we took a picture of the existing wiring setup on the Irritrol and attempted to duplicate it on the new Pi-powered setup. There was no smoke, so we moved on to the next step: screwing the expansion board into the Pi itself so that it fit snugly into the case. Here’s we followed the instructions to a T: we plugged it into the existing orange AC adapter power brick that OpenSprinkler came with. Within an hour, the Wi-Fi worked reliably on the Pi, and by our next session, we were ready to actually test the thing. That way, I didn’t have to remember the IP address each time I wanted to ssh to it. So it took a bit to remember how to get the Pi to play nice on my network I relearned things like setting up the Wi-Fi properly and installing avahi-daemon. I’m a Linux newbie and haven’t worked with the command-line Raspberry Pi interface in awhile. Such was life for our first 18 months, until I discovered OpenSprinkler. If the plants didn’t die, then that meant everything was working properly. It has a crazy-looking dial interface, and after consulting with friends, I decided it was best to just leave it alone. I’m the guy who jumped at the chance to review the Estonian-made Click and Grow.īut our house came with a pre-installed drip system (if keeping score at home, it's an Irritrol RD-600). In other words, we wanted-at the very least-to not kill the plants we inherited from the previous owners. So while some people relax when they do weeding or other green thumb-related activities, we find it tedious and uninspiring. When my wife and I bought our house in 2012, our horticultural mission was Hippocratic (do no harm). ![]() I can control the entire thing locally from my iPhone and, to be frank, it’s pretty flippin’ cool.įor some background, I’m a very lazy gardener.
