Hello, i hate the app from huawei very much, it is so unreliable and produces false information. So i found your nice project. Thanks for sharing. I have a SUN2000-17 KTL-M0, no smartlogger. Unfortunately i have troubles to get it working. If i run python3 main.py i get a timout:

pi@raspberrypi:~/basking-in-the-sun2000/solar-logger $ python3 main.py
mailing error: [Errno -2] Name or service not known

huaweil inv_address error: timed out
huaweil inv_address error: timed out
huaweil inv_address error: timed out
huaweil inv_address error: timed out

I got the ip adress (192.168.178.28) from my router, but this is somewhat a good guess. How can i get the ip adress? Of course it is not displayed in the Fusion app. Also i am wondering: is the port always the same? Do you have an idea how i can get the connection?

Off topic: as i ran your project for the first time, it got errors because the python modules isodate and gpiozero where missing. You can add this to the readme.

Just read here, that the inverter does not communicate if in standby (=no sun). https://community.openhab.org/t/reading-data-from-huawei-inverter-sun-2000-3ktl-10ktl-via-modbus-rtu/87670/6

Thanks for the heads up with the issues you had. Tried to make it clearer in the docs.

Should be included in https://github.com/basking-in-the-sun2000/solar-logger/commit/30972e2447da4379beb51b393ab949cfb2863ba2

Thanks, great to know. Had heard some units didn't respond after sundown.
