A command line tool and python library to query the GOODWE SEMS Portal APIs.

You need to have Python 3 and pip installed. Then:

sudo pip3 install pygoodwe

Determine the Station ID from the GOODWE site as follows. Open the Sems Portal. The Plant Status will reveal the Station ID in the URL. Example:

https://www.semsportal.com/powerstation/powerstatussnmin/11112222-aaaa-bbbb-cccc-ddddeeeeeffff

Then the Station ID is 11112222-aaaa-bbbb-cccc-ddddeeeeeffff.

Please feel free to lodge an issue or pull request on GitHub.

• Based heavily off the work of Mark Ruys and his gw2pvo software - I needed something more flexible, so I made this.

GOODWE access is based on the undocumented API used by mobile apps. This could break at any time.

the main reason I made this fork is to replace python3 f-strings to normal strings, as my Rasberry Pi uses python 3.5.3 (f-strings are introduced in 3.6...)
