With all that out of the way, let’s get down to business. First, open SmartThings on your primary phone. Tap the menu icon in the bottom corner, and then select “Labs.” Look for the “Galaxy Upcycle” service and tap on it. You will see a brief explanation of the feature until the app displays a QR code on your primary phone’s screen.

Now that your device is active, you can use it for monitoring and routines. Here are some examples of what the sensors can do:

• Light Sensor: The ambient light sensor on the phone measures the room’s brightness on a scale of 1-7. This is far more precise than a simple “day/night” schedule. I put the phone in my office and set up a routine that turns on the lights behind my monitor if the reading drops below three.
• Sound Sensor: The phone’s microphone listens for specific sounds, such as baby crying, glass breaking, dog barking, knocking, siren, and more. It can also measure volume and tell you if sound is being detected or not. A simple routine would be to send a notification to a parent if crying is detected.
