Hello, olivierwambacq ,
Regarding your questions:
1) Trips are counted directly by Ruhavik’s algorithms;
2) The speed, as a rule, should be sent by the device itself.
Travel is very much tied to the speed that the device sends, so it is important that your device sends a speed parameter to Flespi.
This case requires additional research.
Please write to us at email@example.com indicating the login and unit ID, as well as add a link to this forum topic, then we can check if your device is sending something other than time stamps and location.
