FAQ

The bulbs flicker. What should I do?

Make sure the bulbs are dimmable, run dimming calibration in the app, and for a no-neutral installation, add a bypass.

Can I set a minimum brightness?

Yes. Set the minimum and maximum brightness and the transition speed.

Is there a night mode?

Yes. During the hours you choose, the light turns on at low brightness.
