How do I activate sleep mode on a Sonos Beam?

To activate sleep mode on a Sonos Beam, one needs to enable the sleep timer feature through the Sonos app. First, open the Sonos app on a smartphone or tablet that is connected to the same network as the Sonos Beam. Then, select the room where the Sonos Beam is located. Now, play the audio content you want to listen to before falling asleep. Next, tap on the "Now Playing" screen, and look for the 'Alarm' icon which often resembles a bell. Inside this menu, find and select 'Sleep Timer.' Choose the desired amount of time from the options provided, after which you want the Sonos Beam to turn off automatically. Confirm your choice, and the sleep timer will be set. The Sonos Beam will now turn off once the specified duration elapses, allowing for energy saving and convenience as one drifts off to sleep.
