Shelly Duo

Create your own sunrise clock

Are you a hard time awakener? Build your own personalized alarm clock with our devices' build-in sunrise schedules. Set your lights to turn on at any brightness you prefer, any time you want, on whichever days of the week you'd like. Use dimming/brightening functionalities to mimic the sunrise to gently wake you up with light, following your body's circadian rhythm.

Smart home office light

Replace your ordinary bulb with Shelly Duo and create a cosy working space! Home working has never been more popular, and adjustable light with cool and warm tones can be crucial to your productivity and comfort. Tune the color to just the right shade and adjust the brightness perfectly to avoid straining your eyes as the day gets darker.

Group your smart lights

Already in bed but forgot to switch off the lights downstairs? Don't interrupt your comfort! Install Shelly Plus i4 with a 4-button Shelly Wall Switch for Smart Relays close to your bed and manually control your Shelly Duo bulbs. You can easily group all the lights at home and use Shelly Cloud app to set various actions based on a combination of clicks. For example: > 1 click on button 1 - switch off/on Shelly Duo bulbs in the bedroom > 2 clicks on button 2 - switch off/on all Shelly Duo bulbs > 1 click on button 3 - switch off/on Shelly Duo bulbs only on the 2nd floor

Smart dimming for children's comfort

Many kids prefer to fall asleep with the lights turned on. Shelly Duo supports schedules that allow you to set the bulb to begin dimming on several stages before it switches off completely. That way, the little one will be comfortably asleep, and no energy will go to waste!
