Arnia - Hive monitoring setup

Wondering if anyone has an Arnia Hive Monitoring system setup with their Flowhive2?
Am very keen to set this up on our own hive but cant quite get my head around how it is all installed on the Flowhives especially the scales. Some photos would be great!
How long is the cable for the weather station?
And finally, are you happy with the set up and how it works?
Many thanks!
