I'll weigh in since I let the thought of getting the Rachio bake for about a year, and it's kinda like this -
I have a wifi thermostat, but I can do 100% on the face of the device if I want to. Likewise my security system. I can control my garage with wifi, but also if I am standing there.
I did not do my due diligence on the Rachio, and when I bought it and installed and then realized the lack of local control, I was kinda bummed. Not real bummed, because I got it so I wouldn't have to trek down to where it is just to do stuff with it, but my first thought was now I have to set my neighbors up with the app and my login so they can kill it if I have a blowout or geyser and we are gone for a few weeks. (Normally we can all go into each other's yards and shut down whatever needs to be dealt with). I guess they could just unplug it, but the app access is fine - we have each other's security codes, so the sprinklers are no biggy.
What would I like on the face? A master enable/disable switch that anyone can use to immediately kill the system.
