Sprinkler 24v input

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?

You will need to use the included adapter for Wyze Sprinkler Controller. Thanks for the question!

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.

Exactly! I already have dedicated power to my sprinkler controller. I can not easily plug in the Wyze included adapter. (not nearby)

I think i will solder a barrel plug onto my existing wires. Then connect the barrel plug to the Wyze controller. That should work…

@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.
