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.
