Rainbird is a total disaster right now and Hunter’s WiFi has been exceptionally unreliable (and no ethernet option). Is Rachio still working on a 2-wire? Release date?
@Quincy - I wasn’t aware that Rachio was even entertaining a two wire solution, so I don’t think so. I doubt you will get an official reply.
I presume you have an existing two-wire irrigation system where two wires leave the controller, goes to each valve in parallel, and each valve has a decoder? I do not think I have seen one of those before and had to look it up. What about using an encoder/converter, such as deVINCI Multi Wire Converter - Aquamonix (the first one I found)?
