I have researched this a bit and found a couple of posts that say this can be done. But I haven't found how to do it. I have an Easy Touch 8 and have spare relays but I'm not sure how this would work. Since the sprinkler valve is low voltage, would I need a transformer between the ET and SV? Yes, I know I could just install a sprinkler control box but I am trying to cut down on all the stuff I have bolted to the wall. Ie trying to keep the wife happy! If there is a way to do this, I would like to try. Thanks in advance.
