With this simple API I then built the OpenHAB binding to use it, so I can now switch on or off valves either manually (via web browser, phone app, XMPP message, etc) or automatically (via rules programmed into the home automation system by me). The only difference is that there is a slightly nicer Java API there. The library code is based entirely on the example code provided by Ray (just written in Java rather than C or Python). The value of this project lies only partly in its use for sprinkler owners, for us it also lies in the clear write-up showing the way for others with similar home automation tasks. ![]() What I did was basically write a very simple Java-based API for controlling valves. Now that I have an OpenSprinkler Pi hooked to my Raspberry Pi, I wanted to be able to control my sprinkler valves from my home, based on rules I’ve provided to OpenHAB. In my home I control various aspects automatically using OpenHAB, and I run it on a Raspberry Pi. Additionally, my binding is free and open source. OpenHAB is basically a free and open source Java-based home automation system. In short, I’ve been working on a binding for OpenHAB (see ) so that OpenHAB can control the OpenSprinkler Pi.

I’m planning on buying the MiFlora sensor and Open Sprinkler Bee in the Black Friday sales next week. Tommy on My Glasses Hear Everything I’m Not Saying! Hi UI Guy At the moment I have my Home Assistant setup all built and running nicely with a few automations and existing senors for temperature, humidity, and presence (via wifi connections).Artenz on Playing 78 RPM Shellac Records: It’s Not Just About Speed.on The Real John Wick-Style Bullet Proof Suit.This Week In Security: Cookie Monster, CyberGhost, NEXX, And Dead Angles 5 Comments Posted in home hacks Tagged ESP8266, home automation, sprinkler Post navigation It’s not the only way to make an ESP sprinkler controller, you should also see this one from 2017. ![]() ![]() The value of this project lies only partly in its use for sprinkler owners, for us it also lies in the clear write-up showing the way for others with similar home automation tasks. The result is a freshly watered lawn, with not a cloud in the sky (or backend). On this he’s been able to tie in all his various sprinkler outputs he added, and apply whatever automation scripts he chooses. The ESP8266 end of the device ties in with his instance of the Home Assistant home automation hub software. This change alone should be useful for many other experimenters with the ‘8266 and ESPHome combination. Plug this into an available zone (either 7 or 8). The black P/MV cable is your pump/master valve. The red zone cables should be inserted into the corresponding zones (Zone 1 on the old system goes into 1 on OpenSprinkler). The interest here lies with the software, in which he’s used the ESPHome firmware and added his own custom part for the shift register. Insert each wire and tighten them down with a small screwdriver. It’s a straightforward enough device, he’s taken an ESP8266 on the ubiquitous NodeMCU board, and added a shift register for some output line expansion to drive a set of relays. But it was this limitation in some commercial offerings that led to create his own controller when it was time to upgrade his aging irrigator. There is something strangely amusing about the idea of a sprinkler system relying on a cloud.
