Hi, I have used the older plugin before, deleted it, restarted domoticz, installed your plugin, restarted domoticz. I entered my credentials in the Hardware tab, and now I see this in the logs:

2022-12-27 16:49:17.594 Error: ZP: (GoodWeSEMS) failed to load 'plugin.py', Python Path used was '/home/pi/domoticz/plugins/domoticz-GoodWeSEMS/:/usr/lib/python37.zip:/usr/lib/python3.7:/usr/lib/python3.7/lib-dynload:/usr/local/lib/python3.7/dist-packages:/usr/lib/python3/dist-packages:/usr/lib/python3.7/dist-packages'. 2022-12-27 16:49:17.616 Error: ZP: Traceback (most recent call last): 2022-12-27 16:49:17.616 Error: ZP: File "/home/pi/domoticz/plugins/domoticz-GoodWeSEMS/plugin.py", line 77, in 2022-12-27 16:49:17.616 Error: ZP: from GoodWe import GoodWe 2022-12-27 16:49:17.616 Error: ZP: File "/home/pi/domoticz/plugins/domoticz-GoodWeSEMS/GoodWe.py", line 28, in 2022-12-27 16:49:17.616 Error: ZP: import requests 2022-12-27 16:49:17.616 Error: ZP: ModuleNotFoundError: No module named 'requests'

There are no new devices to be seen. Can you help me?

Oops sorry. I updated the plugin by using the requests library for more elegant handling of the web requests but forgot to update the installation instructions. They're updated now, can you give it another try?

Basically, this should be enough:

sudo apt-get update
sudo apt-get install python3-requests
sudo systemctl restart domoticz

Thanks, that did the trick for me! Another question: Shouldn´t be the sum of my two strings Inverter input 1 and 2 pwr , the same as the Inverter Output Power? As you can see it is not at this moment. afbeelding

Well no. Firstly, the input powers an average over your refesh interval whereas the output should really accumulate. Then secondly, there would be some internal losses. So the output should be accurate, the input is just an indication to the ratio between the strings.
