Full support for Irrigation Valve in Homekit. All rain delays are set directly from my home automation hub, and not any locally connected sensors. (see included scripts in the config section below) ie :- if rain sensor detects rain, cancel any running zones & delay 24h. ...
Upon connecting the control unit to an oscilloscope, I noticed something strange: no matter how I press the on/off button, it’s only sending a very short (a few milliseconds) pulse, which cannot possibly operate the valve. Then it became clear to me that the controller is in fact active...
[Ray] wrote in to share a great project he just recently wrapped up,an open-source sprinkler valve controller.Built in collaboration with Wired Magazine’s editor-in-chief [Chris Anderson], the sprinkler controller is designed to replace the limited commercial sprinkler timers that typically come ...
Well, things seemed pretty good this spring despite no fall blow out, but by midsummer I'd become aware of several new water line leaks in parts of the system where the water has no where to drain, like in the main line between the backflow valve and my valve box. I ended up having...
An adjustable stator is mounted in the lower end of a pop-up sprinkler riser and includes a vertically extending frame portion and a pair of valve portions that extend horizontally from an upper end o
Try manually turning it on by setting the dial to the valve number you want, press + to add some minutes, then press the lower right “manual on” button. You should see a small number for the valve number appear on the top of the LCD screen. Let me know if you see the number or...
A trim manifold assembly is utilized to facilitate control of the control valve in a fire protection system. The trim manifold assembly utilizes a manifold block with numerous passa
This is quite strange to me: how come closing the valve only requires such a short pulse and such low voltage? How Does This Latching Valve Work? In order to figure out what’s going on here, I un-tightened a bunch of screws and opened up the valve. At the bottom of the valve is...
Along the mainline there are enough valve outlets or hydrants for the laterals to be connected. While in the CHL system (Figure 1b), the main or sub-main pipe is shortened to the plot center. The only required valve outlet, which is a pivot elbow rotation valve for the single lateral,...
