I have 4 EZ rain irrigation controllers of various vintages. Of the 32 total zones, there are a few dead ones, a few of the triacs have had the smoke freed from them. You'll also need a 24v transformer. I ended up going with OpenSprinkler, which has the gardener wife approval, and having a single device for all the zones is just easier.
Free to a good home for the cost of shipping. Or shipping on my dime if you have written and shared an Indigo plugin.
