Goal: Extract Solarpanel data from SEMS for Goodwe inverters.
Based: on the works of https://github.com/markruys and https://github.com/dylian94 and http://euapi.sems.com.cn:82/swagger/ui/index SEMS API information. Dylian developed a Domoticz solution for Goodwe inverters. See Mark Ruys for how to find the Goodwe powerStationId.
Tooling: This simple solution is based on Python3 and mqtt and runs on an Raspberry Zero. The program is executed on request of a simple workflow in Node-Red.
