Hi All,

My first post 🙂

I can upload with no problems, however, I’m getting large gaps in my basal graph. Even the dotted line is missing. Does anyone know why? Also, just after midnight there is a grey information dot that says “We have fabricated this basal…”. Does not inspire confidence that my pump was uploaded correctly.

Any info would be appreciated!

Please contact [support@tidepool.org](mailto:support@tidepool.org) regarding the basal gap you’ve shared so the Tidepool Support team can troubleshoot this issue with you.

With respect to the overnight indicator, that’s related to how data is provided to the Tidepool service from the pump. Because of how basal segments are generated on the pump, we have to infer the basal rate between 12:00 am and 12:05 am based on device settings. After that, we have more reliable start and stop times for a given basal segment.

Again, contacting [support@tidepool.org](mailto:support@tidepool.org) is the best way to get a efficient answer on these matters.

(Sincerely, Tidepool’s Community and Clinic Success Manager)
