If your devices are malfunctioning, or you want to give them to a friend, or you just don't like how you have things set up and want to start over, a factory reset might be the answer. Factory resets return your device to its default settings and erase all of your stored info. Once it's done, you can start fresh. Fortunately, lots of smart-home devices still make this easy. So put the hammer away, and solve your glitches the less destructive way.
Though it's becoming less common, plenty of smart-home devices still have a reset button hidden in a small hole on the bottom or back of the device. Look for this first if you want to do a factory reset, and have a paperclip handy, as you'll need one to reach these buttons.
The Philips Hue bridge has one of these buttons. If you're having trouble with the bulbs, flip the bridge over, and you'll find the button on the back. Use a paperclip and hold it down and you'll reset the bridge and any bulbs synced to it.
Keep holding the button for 5 to 15 seconds while the switch is plugged in, and you'll notice the light on the top start to blink amber. You can release the button at that point and the switch will be ready about a minute after that.
You'll need to hold the button on Piper for a few seconds until the light on the front of the camera shuts off. Leave it powered down for a minute, then hold the power button down until flashes between red and yellow before turning solid yellow. Release the button and wait a few minutes for the light to turn blue. Once you see the blue light, the Piper NV is ready to be setup anew.
Not all smart-home devices have a physical reset button. In fact, they're becoming less and less common. The August Smart Lock is one such device. If you want to return a lock to its factory settings, you'll need to do so in the app. Be extra careful when giving these to a friend if you've already used it. You'll want to make sure you've reset it with your app or your friend will have no way to start fresh without contacting August's customer support. Use the settings icon to start the reset process.
