Hi @bkiesbauer I am trying to test your driver. I copied all the files to the directory and rebooted. Its not showing any data, how can i set up and check the correct USB device?

EDIT:
Its working now. I had to swap A&B again on one side and configure the baud rate on the meter to 19200, the default password is 1000 by the way if anyone else needs it.I am now using the following:
Counter: https://amzn.to/3LBlkum (currently only costs 51.50 EUR)
RS485 USB adapter: https://amzn.to/3Jw5lL8 (the version with FT232RL chip, currently 18.50 EUR)
So why spend so much on an ET340 that doesn't even have a display?
@bkiesbauer
Short Feedback:
L2 and L3 need to be swapped within the driver so that it will fit to the meter display.

Hi @bkiesbauer,
thanks for the adapter. Works in principle, but with different sign the displays are not correct for me. With L2+L3 the sign is missing at the current and the sum is formed incorrectly. With different signs of the representation in the picture is not correct at all.
Do you have an idea?
Is it still working with 3.13 oder 3.20 ?
