Every year when the temperature drops, there’s an uptick of muted panic that appears online from smart home owners wondering whether their outdoor devices like video doorbells and security cameras are dying. Here’s what to do to get your outdoor devices functioning correctly when the Great Outdoors is trying to freeze you out of your own smart home. Check the device manufacturer’s user manual, because it might not eliminate your winter charging problem. With some smart home devices, even hardwiring it to your house or apartment’s electrical system doesn’t completely bypass the battery. As for its Nest Doorbell, the hardwiring trickle charges the battery, and then the device runs off the battery, which—you guessed it—won’t charge below freezing.
