Experimental Features

For the experimental features to be activated you need to add them in the config file of the platform, e.g.

{
  "name": "Levoit Air Purifiers",
  "experimentalFeatures": ["DeviceDisplay", "Humidifiers"]
}

---

1. Show the display's switch as a light in the app (DeviceDisplay)

The read data is cached for 5 seconds to not trigger the rate limiter for the API. Each request is delayed by 500ms to not trigger the rate limiter if a huge number of requests are sent.

The timers are not included because you can accomplish similar results by using Home App's Automatization or the Shortcuts app

2. Discovers supported humidifiers (Humidifiers)

Configuration

• Via the Homebridge UI, enter the Homebridge VeSync Client plugin settings.
• Enter your VeSync app credentials.
• Setup the platform plugin as a child bridge for better performance
• Save and restart Homebridge.

This plugin requires your VeSync credentials as it communicates with the VeSync devices via VeSync's own API. Your credentials are only stored in the Homebridge config and not sent to any server except VeSync's.

You can also do this directly via the homebridge config by adding your credentials to the config file under platforms. Replace the values of username and password by your credentials.
