5 ways to repurpose an old Android phone
How many phones have you owned over the course of your existence? I generally promote my old ones, but generally there’s one that’s either no longer value remarkable or isn’t in good condition. That doesn’t mean they need to sit around in a drawer. Here’s what you want to enact with that old software.
How to flip your old Galaxy phone into a smart sensor
First of all, your old phone or tablet can’t be too old. It wants to be a Galaxy S9, Point to 9, or more moderen. Essentially, most Samsung phones operating Android 9 or later will work. The primary software wants to be a Samsung phone as successfully, unfortunately. Galaxy Upcycle is repeat in the “Labs” piece of the SmartThings app, but it certainly’s no longer repeat on non-Samsung phones.
With all that out of the way, let’s get down to industry. First, commence SmartThings to your primary phone. Tap the menu icon in the bottom nook, and then decide “Labs.” Search for the “Galaxy Upcycle” provider and tap on it. You will stare a temporary explanation of the feature till the app displays a QR code to your primary phone’s display.
Grab up your old Galaxy phone and exercise the camera app to scan the QR code. This can automatically commence the Galaxy Store page for the Galaxy Upcycle app. Install it. Start the app and wade thru the prompts. Resolve whether or no longer you want the software to feature as a “Light Sensor” or a “Sound Sensor.”
You’ll now add the “sensor” to your home in SmartThings. Assign the sensor to a particular room and then give it a unique name if you happen to’d admire. After the sensor has been added, you can tap “Turn off display” to place the phone into a low-energy Upcycle monitoring mode. This requires granting the app admin access to your phone. You’re all accomplished!
It’s conceivable to exercise your software as each a light sensor and a sound sensor at the same time. Start Galaxy Upcycle and tap the menu icon in the top nook of the sensor display. Pick “Manage Gadgets” and then tap the plus icon subsequent to the sensor you haven’t enabled yet. Practice the steps to get it house up.
The exercise of your unique sensor in SmartThings
Now that your software is active, you can exercise it for monitoring and routines. Here are some examples of what the sensors can enact:
Light Sensor: The ambient light sensor on the phone measures the room’s brightness on a scale of 1-7. That is far more precise than a straightforward “day/night” schedule. I place the phone in my office and house up a routine that turns on the lights in the back of my monitor if the reading drops below three.
Sound Sensor: The phone’s microphone listens for particular sounds, such as baby crying, glass breaking, dog barking, knocking, siren, and more. It can also measure volume and say you if sound is being detected or no longer. A straightforward routine can be to send a notification to a parent if crying is detected.
Now, it’s clearly no longer cost-effective to exit and purchase a bunch of old Samsung phones to exercise as smart home sensors. However, the usage of what you already have is always a good factor. Don’t let an old phone rot in a drawer when it can make your smart home more worthy.
