qingping air monitor lite support

[zefir-o]

If you are receiving a warning indicating an unsupported model (Found an unsupported model '<model>' for class '<class>'.),
this means that the implementation does not list your model as supported.

If it is working fine for you nevertheless, feel free to open an issue or create a PR to add the model to the _supported_models (example) for that class.

Before submitting, use the search to see if there is an existing issue for the device model, thanks!
