The instructions at http://support.rachio.com/article/210-detailed-installation-guide-updated state
- Download the Rachio app, plug in the Iro and complete the WiFi
blink-up procedure. Be sure to complete this step before you remove
your old irrigation timer!!
Subsequent steps then walk you thru disconnecting your old controller and hooking it up to the Iro.
I thought I was good to go, but then decided to watch the videos (a picture being worth a 1000 words, and all that)
There are 2 install videos at http://support.rachio.com/article/236-quick-install-videos The lower video, titled “Installing the Iro Wifi Sprinkler Controller” also assures the user that installation is simple, however it insists on the reverse order! At around time 10s into the video the box is unpacked. Step 2 at time 34s is to unplug the old timer, subsequent steps go thru the attachment, and at the end of the video at 2:26 they say to go over to the app setup.
So does order matter, and if so which one is right?
