When adding new integrations, limit included platforms to a single platform. Please reduce this PR to a single platform

As the bot said, please limit this initial PR to only one platform (for example, only switch.py) and remove all others. Once this initial PR is merged you can start adding more platforms, one after another in a separate PR. This helps reducing the review effort and your PRs get merged faster.

[elmurato]

And also please link your documentation PR under the chapter Additional information.

You can also remove the chapter Breaking changes, as this is a new integration.

One more point: It looks like your config_flow tests are missing. You need 100% test coverage for config_flow to reach the minimum quality scale bronze.
