Xiaomi Mi Air Purifier & Xiaomi Mi Air Humidifier

This is a custom component for home assistant to integrate the Xiaomi Mi Air Purifier 2, Air Purifier 2S, Air Purifier Pro, Air Humidifier, Air Fresh and Pedestal Fan.

Please follow the instructions on Retrieving the Access Token to get the API token to use in the configuration.yaml file.

Credits: Thanks to Rytilahti for all the work.

What is the difference between this custom component and the one in Home Assistant Core?

This custom component is more or less the beta version of the official component. Furthermore, this custom component supports a number of additional devices which cannot be merged into the official component at the moment. The handling/values of the fan_speed property need to be refactored first because this and the official component don't align with some new architecture decisions.

Supported devices

Unsupported devices:

• Mijia Humidifer 4L (MJJSQ02LX): This device isn't smart / has no WiFi support.
