Zhimi.humidifier.ca4 issue

For Xiaomi Smartmi Zhimi Air Humidifier 2(zhimi.humidifier.ca4)
in the “bright Dimmer LED Brightness” dimmer type seems to be incorrect. Because it’s impossible to set to Brightness level this way to a high level.
I’ve changed the line:

Dimmer bright "LED Brightness" (G_humidifier) {channel="miio:basic:humidifier:bright"}

in “Xiaomi Mi IO - Bindings | openHAB” to:

Number bright "LED Brightness" (G_humidifier) {channel="miio:basic:humidifier:bright"}

And was able to set display brightness accordingly:

0=Off;
1=Dim;
2=Bright.

Am I right that “Dimmer” allows to change value between [0…1] with step ~ 0.05?
Offtopic
For “Mode”, if someone will see this who’s trying to make the config:
The values are:

0=Auto;
1=Silent;
2=Normal;
3=Maximum.

Can you make a github issue for this.
I’ll update the db file to fix this when I have a chance
