Meanwhile I figured it out....

After installing the drivers, I needed to restart the Domoticz docker container. Now it sees the P1 cable and data is logged from it.

BTW, I am using the ftdi_sio driver now, in combination with the usbserial driver.

Thanks,
John

Hi RCS42,

I tried your instructions but am (still) stuck...

My problem:
- I had a working setup using the Jadahl package on DSM6.2 running on a DS416Play. This setup used the P1 smart meter interface for utility data logging.
- I updated to DSM7.0 without realizing that this would break this setup ...
