SlimmeLezer YAML for Austrian Smartmeters

ESPHome
1

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...
Failed config

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

Hello, is there any news? Have you been able to solve the authentication? I also have a Slimmelezer at E-Netze.

Hi Bernhard,
do you found a solution? I need also a working yaml for Slimme - in my case Netz NÖ and a Kaifa Smartmeter.

Danke
