The flukso v2 requires additional parameters to be passed with the request. Please note that you have to use port 8080 to receive a downloadable file with the measurements in it.
http://:8080/sensor/?unit=watt&interval=minute&version=1.0
You could use curl to access the file:
curl --url "http://:8080/sensor/?unit=watt&interval=minute&version=1.0"
