What is the light ring?

The Wave and Wave Plus have a light ring which looks like this:

And the color changes depending on the air quality:

GREEN: All sensors indicate good air quality 😀

YELLOW: One or more sensors indicate fair air quality 😐

RED: One or more sensors indicate poor air quality 😣

Temperature does not affect the color of the light ring.

Simply move your hand in front of the device and the ring lights up with the corresponding color!

You can then check what exactly the color means in the app:
