Modbus USB-RS485 Help

[omlnja]

I do also get this problem on Raspberry PI. Trying to move from Windows to Raspberry and need to get this working. Any updates?

[Heychristian]

i am not familiar with RS485 programming, and i have a dimmable transformer that has 3 lines in for RS485 control. i prefer to use a ZeeS2 but can use windows 10 HomeTroller if needed. i have a USB-to-RS485 adapter. can anyone advise how i can have Homeseer send the following RS485 command to the transformer, which steps down the voltage from 110 volts to 45 volts: thanks in advance, Chris
