SlimmeLezer YAML for Austrian Smartmeters

I’m gonna try to get the YAML for ESPHome compiled to work with two Encryption Keys. As it is the first time in my life where i touch a YAML file, if some experienced of you can check the code and help me to avoid the Error message.

Error:

INFO Reading configuration /config/esphome/slimmelezer.yaml...

dsmr: [source /config/esphome/slimmelezer.yaml:84]

This is the current YAML:
