Not exactly what this means, but here is my latest response from customer service:
"This is Ana G. from Rachio Customer Support. Thank you for reaching out!
This has been escalated to the engineering team in order to get the 6-digit code you might be missing to properly integrate the Tempest on the Rachio App.
Once I have an update for you, we will let you know but for now, since this will also require an app update release, I can’t provide a time frame on when will this be resolved.
Thank you for the time and patience, we really appreciate it!"
