Components that interact with devices are structured in core- and platform logic. This allows the same logic to be used for different platforms.
For example, the built-in switch component consists of the following files in homeassistant/components/switch/:
| File | Description |
|---|---|
| __init__.py | Contains the Switch core logic. |
| wemo.py | WeMo platform logic. Included if in config platform=wemo. |
| tellstick.py | Tellstick platform logic. Included if in config platform=tellstick. |
If you are planning to add support for a new type of device to an existing component, you can get away with only writing platform logic. Have a look at how the component works with other platforms and create a similar file for the platform that you would like to add.
Platform logic should not interface directly with the devices but use a third-party Python 3 library that speaks the actual API.
