**Status:** Fixed since May 2025

**How to recognise it**  
You saw new trips pushed for the same temperature-logger device serial even when a trip already existed. The same serial could appear in more than one trip. Tracker files could contain more trackers than expected because some device IDs were linked twice. Temperature data could be missing.

**Which shipments this affects**  
Shipments with a temperature-logger device that was scheduled more than once in a day. The issue was about the same temperature-logger serial.

**What changed**  
Dockflow now does not schedule another activation for the same temperature-logger device within a day. Before, the same device could be scheduled again repeatedly.

**Is past data corrected?**  
Nothing to correct: the change affects how new data is read.

**How to check your shipment**  
Open the trip list or tracker file for the shipment. Look for repeated trips for the same temperature-logger serial. Contact support if you still see many duplicates for one serial.

**Do you need to do anything?**  
Nothing.
