We will continue to monitor the system. It is strange that it was running but no reported history. If the controller is online we should be getting those watering notifications.
If you have setup any third party integrations (i.e. IFTTT, Wink, Nest, etc.) please disable those as it could cause they system to run without your knowledge.
If you see any other odd behavior firstname.lastname@example.org can help with researching this issue.
Thanks and have a great day.
