Custom_component and custom_platform Camera

Development
1

okay, i want to overhaul the camera component and make a custom_platform for it.
but not in the acutal code, i want to utilize the custom_component and custom_platform features.

i started by simply copying the exiting

  • __init__.py hxxps://github.com/home-assistant/home-assistant/blob/dev/homeassistant/components/camera/__init__.py
  • _mjpeg.py hxxps://github.com/home-assistant/home-assistant/blob/dev/homeassistant/components/camera/mjpeg.py

and saved them like this:

.homeassistant:
±–custom_components
| |
| —ccamera
| ------mymjpeg.py (renamed -mjpeg.py)
| ------__init__.py (i just renamed the DOMAIN to: ‘ccamera’)

then i added the following entry to my configuration.yaml:

ccamera:

  • platform: mymjpeg
    mjpeg_url: ‘EXAMPLE_URL’

no errors launching just homeassistant. however once i open the frontend and want to see the camera, the following error occurs:

AttributeError: ‘EntityComponent’ object has no attribute ‘get_entity’ in __init__.py line 368

everything works just fine using the original build-in components like this:

camera:

  • platform: mjpeg
    mjpeg_url: ‘EXAMPLE_URL’

ALSO: in -mymjpeg.py, line 20 imports from the built-in component rather the custom one ‘ccamera’. trying to change it results in ‘no module found’.

any help appreciated. =)

I believe get_entity was introduced in 0.62. Do you have 0.62 installed, or do you have an older version installed and then download the camera component from github?

Jesus, yes that was indeed the problem. Also the in order to import classes from custom_components, the line needs to be changed to:

from custom_components.ccamera import MyClass

instead of the more obvious approach:

from homeassistant.custom_components.ccamera import MyClass

Thank you very much =)
