Hi,

Hi,

Can you read the meter with an optical probe? The optical sensor cable should point straight down.
Try to change the address type from serial number to Default when connecting with an optical probe.

Mikko

Hi,

Hi,

Active energy should be found under register objects, not data objects. Try to find it there.
All the objects that you can access with current access rights are shown on the left side of the application.

Mikko
