Problems with node-red-contrib-smartlifeair

First try pressing refresh channels. But I guess you have already done it.

Yah, That happens sometime. Some manufactures customize the firmware and map to their own UIs instead of the generic UIs. At this point you are out of options.

But I usually use a way around it by setting up an automation rule in the app

Example
You can turn this light on when the other light come on
