Self coded Integration will not found in config/custom_components

Third party integrations
1

Hallo I have a problem.
If I follow the guide of Home Assistant how I setup a own Integration. This Integration will not be found.
I try it in different cases in the configuration.yaml file.
sensor:

  • (- platform: “mte”)

or
only

  • mte:

the error is every time the same. I do not understand wats going wrong.


Configuration warnings

Platform error 'sensor' from integration 'mte' - Integration 'mte' not found.

here is the file structure

my codes are the same like the one of the following link :
example-custom-config/custom_components/example_load_platform/README.md at master · home-assistant/example-custom-config (github.com)

the only difference is, I had rename the Integration and hence the Domain in ‘mte’

I hope someone can help me …
It seemes like I have the wrong file structure.

thanks in advanced

Yaml doesn’t include bullet points. Could that be your problem.

Did you update the manifest as well?
Please make your whole code available.

:rofl::rofl::rofl:

Here my files:

    # Data that you want to share with your platforms
    hass.data[DOMAIN] = {
        'temperature': 23
    }

    hass.helpers.discovery.load_platform('sensor', DOMAIN, {}, config)

    # Return boolean to indicate that initialization was successfully.
    return True

and for the nice guy who means I use bullet points in Yaml the snip of my
configuration.yaml file :wink:

type or paste code herehomeassistant:
  packages: !include_dir_named 

# Loads default set of integrations. Do not remove.
default_config:

# Load frontend themes from the themes folder
frontend:
  themes: !include_dir_merge_named themes

And you assume I can speak German because…? :wink:

Sorry … english … no problem … :slight_smile: I posted my Code … every File which is relevant, I think so. Only the configuration.yaml there I hide something in the http.: - part.
