@Mopi -- I'm reviewing your support ticket and it appears you have DC solenoids. Can you please send us photo of your rewiring or post here for review?
DC solenoids are not compatible with our controller, as outlined in our technical specs both on our website and support site. For more information on the common misunderstanding of AC and DC solenoids, please see this 3rd party article.
I understand your frustration, however Rachio has been very responsive to helping you since January 7th. We've offered to replace the controller and/or take it back. This offer stands -- I'll personally reply to your support ticket with options moving forward to make things right for you.
