Add support for Levoit Classic 300S Smart Ultrasonic Top-Fill Cool Mist Humidifier in the VeSync integration

Great Work! But sadly i got a Problem finding my Dual 200S after adding the Integration. I can input my username etc. when setting the Integration up, and the Humidifier also shows up in the app, but there is no entity added. I tried to remove the Integration and also the Device in the App, but nothing shows up, what could also be a possible Problem? I start to feel stupid since its working for everyone else… :confused:
