As beacons are provisioned, they are added to the system under your "Assets" category in the app:

From here, you can download a CSV file that will list all the beacons and their assigned assets, along with some additional information.

Beacon Mac Address: Internal unique identifier 

Category Name: (hot water tank, air conditioner etc)

Unit ID: Last 4 or 5 digits of the Asset's Serial Number (note, last 5 digits is preferred, but 4 is fine as well!)

Location Name: assigned location/home location

Name: Asset Name/Number

Manufacturer: self explanatory

Model Serial Number: self explanatory

This CSV file should have everything you will require, without additional input necessary!
