Good day.
Srs Developers/Community.
I wanna say hello and thank you in advance for your help.
Im trying to connect a EMH meter LZQJ-XC (https://www.emh-metering.de/en/products/spezialzaehler/lzqj-xc) using GURUX Linux version and Python without success. I really dont know the default settings of these meters in the Tools/Manufacturer Menu, and when created, in the Device Properties.
We are using usb optical probe IEC 62056-21 for our connection

The informations about accessing the data of these meters is very limited on the web. For that reason im looking for help in the forum.
Best Regards,

Hi Touihrihanen,
Hi Touihrihanen,
You don't have access rights for your serial port. You need to run this with sudo or add access rights to the serial port for your user. Try with this:
sudo gpasswd --add ${USER} dialout

Hi,
Hi,
Try to add -i parameter. I can't remember is EMH using IEC 62056-21 when the connection is established using the optical head. You can try to change the baud rate if this fails.
