This may be useful for anyone who wants a HE-controller garden hose valve controller but has a small front/back yard.
alex_sari, an eBay seller from whom many of us have purchased Iris outlets and sensors has Iris/Orbit zigbee valve controller available for sale. These are meant for garden hose faucets. They are listed as being used, but the one I received was brand new.
There's a built-in HE driver for these, making it easy to setup conditional rules to water. I've had one of these for a few years and purchased a second for my backyard.
