My old sprinkler controller system has 24v power supply wires already.
Instead of using the barrel plug to provide power, can i use those existing 24v wires by connecting them to the 24v gray terminals that are next to S1/S2 terminals?
In other words, can those 24v grey terminals be used to power the unit as well as power remote sensors?
Its unfortunate that they went with a plug instead of the ability to wire the system into the existing dedicated line. All of the new build houses in my area have dedicated power to the controllers. I got a weatherproof box from Amazon that has a built in outlet that I am going to use to install mine.
@mike.s Can you update us on what the 24V terminals on the sprinkler controller would be for otherwise? I installed mine using the existing transformer that was already in the box, into the 24V terminals on the Wyze unit and its been working just fine.
