Hello,

I do have a DTU-pro and DDSU666 from hoymiles connected using the RS485 port . Are your scripts working with DDSU666 hoymiles or should I use a Standard DDSU666 ?

Can you please also confirm that the following connection is the correct one

DDUS666 -> DTU-Pro
DTU-Pro -> Waveshare Industrial USB to RS485

sorry for such maybe stupid question :-)

Thanks for and help / advice.

hi, see first https://www.youtube.com/watch?v=IomXSOtnlgg RS485 is a bus, like a "chain", device connection order doesn't matter
