sample python-code to Query the Goodwe Sems-Portal via HTTPS
Dear all,
this small script provides basic building-blocks to query the GoodWe Sems-Portal. The token can be-reused, means subsequent calls can make use of an existing authentication-token. If the tokes expires, the script will renew the token and continue querying the portal.
You need to create a credentials file called: sems_config.py
While Username and password (single or doublequotes are just fine) are trivial, the power-station-id is somewhat non-trivial. Easiest way to aquire it, is to login to via your PC,Tablet,.. to the Sems-Portal and look at the "resulting"URL after you looged-in successfully. it will read: https://www.semsportal.com/PowerStation/PowerStatusSnMin/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Check the xxx stuff - that your ID!
behn@rpi5:~/jk_venv $ cat sems_config.py
username = "<your email-Address>"
pw = "your password on the Goodwe Sems Portal"
power_station_id = "<aquire this from the URL as described aobve>"
behn@rpi5:~/jk_venv $ ./sems.py

Parsing the JSON-String to derive Battery : 49.9V/0.8A/40W
- battery-Power[W], Battery_Power[A] 0.8 40
Reversing the logic and multiplying the values with -1
- battery-Power[W], Battery_Power[A] -0.8 -40
Success
