Issue with eBZ DD3 Smart Meter

Hello Community,
today I was trying to setup a eBZ DD3 Smart Meter into my HA environment (Raspberry Pi) through optical IR USB2Serial head…no luck :frowning:
USB-Serial Converter was found in HA, but no entities showed up, neither on front interface nor on top interface.
HA is uptodate, so EDL21 configuration is no more visible in configuration.yaml, is there a special “trick” to setup such kind of D0 smart meter?
Thanks in advance!

I hope this will help:

This is my configuration for the sensor.

Hi Andre,
partially yes. It seems your code snippet is not complete.
There should be anywhere a definition of the read data from serial port, otherwise it looks like this:

Is there more to provide?
