I keep getting an “activation failed” setting when I enter the serial number. This is a new unit that Rachio sent me and was delivered today.
Hopefully Rachio will help. You can call them tomorrow. Sometimes it takes a few attempts. This is what I have found with all the wifi controllers I tested. Rain Bird’s wifi controller took about 12 attempts. I remember watching some Gen 2 videos on youtube
Definitely call. I ended up having to do so when my wifi wasnt connecting properly during activation. Turned out the controller had been reset back in the factory and thus it didn’t know “how to call home” to the Rachio cloud server.
As our great helpers have already suggested, please contact firstname.lastname@example.org or call into our Support Line at 1-844-4-RACHIO ASAP and we’ll happily get to the bottom of this and set you up with your new controller.
Please be sure to include the Serial # on the front panel of the device as well
Looking forward to your call!
