This script performs a web login to a Huawei E5172 3G/4G/LTE CPE's (router/AP) web interface and scrapes off its volume usage statistics. For example Swedish mobile operator 3 uses these.
Should probably work with other models using similar web code.
Tested with E5172S-22 (hw rev B), firmware revision: V200R001C24SP100 (build time: 12/6/2013 20:41:35).
