No sensor data when subscribed to mosquitto broker

I got my Flukso V3E yesterday and data is showing up fine in the dashboard on but I cannot get any data when subscribing to the mosquitto broker.
I am using the following command via SSH on the flukso to subscribe to all sensor data:
mosquitto_sub -h localhost -p 1883 -t sensor/# -v

Am I doing something wrong? On the mqtt tab on the flukso webinterface I see live data so the data must be present.

Thanks for the help!

EDIT: My bad I forgot the slash in the beginning :-) => /sensor/#
