Hi @mikeT, good evening. Thanks for reaching out.
I appreciate you bringing this to our attention. Looks like I had a typo on the detailed install guide. I apologize for the contracting instructions and will correct this.
Either way works in reality, but I'd recommend installing the hardware first (wall mount and wiring), then connect the Iro to WiFi (blinkup), followed by setting up your account/sprinklers on the app.
I hope this helps. Let me know if you have any other installation questions I can help with.
