Hi, @slunceford -- sorry for the late reply on this.
Occasionally the Gen2 units have trouble synching up with our cloud servers. It sounds like this is where you're at, with 4th light blnking. This is rare, but easily remedied.
If only I'd caught this yesterday, we'd have you up and watering today!
Is the controller still in the state described above?
If so, please send an email to Support@Rachio.com and we can take care of this for you.
* the Serial Number (starts with 'V' for Gen1, 'VR' or 'CR' for Gen2)
* your Rachio app username or email (if different from the one sending request)
We'll open a ticket to get you squared away post-haste!
