@joelde Joel, just to clarify between the Iris & Orbit device…
The Iris device is designed for interior use by the very nature of its 2 connection points; you may have to adapt this size to AU use as appropriate. It is not programmable and only has an open & close state. It is really intended for a whole house scenario as one would typically place it immediately after the main house water shut-off valve, which is typically inside the house in the Northern Americas. Nothing however stops one from hooking up inline to an outside faucet line, but again that will typically be inside the house, and depending on accessibility , this may also dictate placement. Speaking for myself, my biggest (only) issue with the device has been mesh signal strength which I readily fixed with a repeater.
The Orbit device appears to be programmable and is designed for outside inline use by connecting it between the faucet & the (for lack of a better word) hosepipe. Again, you may need to adapt the connections to fit UA size & style. Perhaps existing users can elaborate further on the capability, suitability, and more important, the problems encountered with the device in the ST environment.
