I think you're using some fork. I don't use mpp-solar or python 2 here

Ah wait. You're trying Axpert Command and that is in another repo that hasn't been maintained

[heibertelf]

You're trying Axpert Command

Yes. I have Sila invertor, it could be compatible, but when i try Axpect monitor addon, it says

/dev/hidraw0
QPGS0
error reading inverter...: NAKss
/dev/hidraw0

In another thread i read that Command can help.
My invertor connected directly to haos server via usb port (without rs232 converter, it have own onboard usb port), can this be a problem?

It's possible the device is not hidraw0 if you have other usb devices.
Or it might just not be compatible
