VeSync development particularly for Levoit Humdifiers

I’ve been using Levoit Classic 300S Smart Ultrasonic Top-Fill Cool Mist Humidifier with VeSync app (v 5.0.70).

I can only set the mist level in the manual mode, which can sometimes result in over humidifying a room. Should it be also possible to set the humidity level (in percentage or percentage range) in the auto mode?

Thanks!

It appears that the originator of the custom integration has abandoned it. Has anyone figured out how to integrate a Levoit 300 humidifier without his integration?
