The big question now: Will there still be an OpenSprinkler interface to Weather. OpenSprinkler is an open-source, web-based sprinkler timer / controller. OpenSprinkler is an open-source Internet web-based sprinkler timer / controller built upon the Arduino platform. If I want to change a switch and avoid effect of loop triggering, then I need to ignore triggering happened just after I change the switch. OpenSprinkler AVR/RPI/BBB Firmware This is a unified OpenSprinkler firmware for Arduino, and Linux-based OpenSprinklers such as OpenSprinkler Pi. Forecasts update approximately once per hour. Some people prefer using internal scripting mechanism based on LUA or Python. You can update the firmware at any time by reflashing the. In my case, i use MQTT Client Gateway with LAN interface so any changes in switches are dumped in MQTT topic domoticz/out where I can catch them using Node-Red and process as I want. The OpenSprinkler firmware is regularly updated to include new features and functionality. You can also configure your home network to allow access externally from anywhere (depending on your comfort level for setting this up and exposing to the internet in general).It's a development platform so you have to develop any deviation from the functionality you are given. With all of the above you’ll have mobile access, but only on your home wireless network. (I know, the exciting life of a homeowner!) For me this was one of the best use cases: while I’m out adjusting sprinklers I can remotely turn each zone on or off. Once you have the software configured, I recommend downloading one of the OpenSprinkler mobile apps so you can control everything from around the house (via Wi-Fi). If you attach a rain sensor, the OpenSprinkler can also operate in a smart weather mode where it decreases the amount of watering based on local rain or weather forecasts from Weather Underground. Programming the schedule is pretty straightforward as well. You can give your zones nice names like “front lawn” or “back roses” so you don’t have to remember zone numbers. The more interesting part is the software which is easy to set up from a web browser. My original 20+ year old Lawn Genie controller My new OpenSprinkler installed Software Our new website is now alive Updated User Manual and API documentation are now hosted on the new site. Here’s a comparison of the old Lawn Genie and the new OpenSprinkler: OpenSprinkler Firmware 2.1.0 is released. (The OpenSprinkler itself does not have Wi-Fi.) You’ll also need to connect to your home network with an Ethernet cable. Newer firmwares can no longer run on OS 2.0, 2.1 or 2.2 due to code size. NOTE: from firmware 2.1.9, only OS 2.3 (and above) will be supported. All the cabling is compatible (assuming you have the standard 24 VAC controllers), so it’s just a matter of reconnecting everything to the OpenSprinkler. OpenSprinkler 2.x supports firmware update through the controllers USB port. Replacing my old Lawn Genie controller with the OpenSprinkler controller was really simple. Getting certified is still on the to-do list according to this OpenSprinkler update from Feb 2015. There is also the possibility that if OpenSprinkler can get certified by the EPA WaterSense program, that rebates from water agencies could be possible (similar to low-flow toilets, energy-saving water heaters, etc.). OpenSprinkler started out as a hobby kit for makers and they still sell it a variety of ways, from kits to completed units. Rather than waiting around for Nest, I just bought and installed an OpenSprinkler. Especially here in California (where we are in a pretty serious drought), having better control over irrigation (not to mention the remote access) seems like the logical next step. At the time we talked a lot about the obvious next step of supporting home sprinkler/irrigation controls. My friend Jeff Cable was one of the early adopters of the Nest thermostat.
