Working with VKW Honeywell DM515

[g0mml]

Thank you for your effort @DomiStyle 👍

Works with VKW Honeywell DM515 smart meter using the following config:

esphome:
  name: vkw-waerme
  platform: ESP32
  board: az-delivery-devkit-v4
  includes:
    - ./esphome-dlms-meter

# Enable logging
logger:
  level: INFO
#  tx_buffer_size: 2048 # Only needed when logging large packets

# Enable Home Assistant API if not using MQTT
#api:
#  password: "1234"
#  reboot_timeout: 0s
