As you can probably guess, if your power goes out in your home or apartment, your Philips Hue lights will go out with it. At that point, a smart light bulb is no more or less useful than a regular bulb—after all, regular bulbs would go out too.
However, when your power comes back on, every single one of your Hue light bulbs will turn back on, whether or not they were turned off at the time of the power outage. They’ll also revert back to the default soft white color temperature, no matter the color state they were in when the power went out.
This means that if the power goes out in the middle of the night and turns back on, expect to be woken up by your Hue lights blinding you. Unfortunately, there’s no way to prevent this from happening, but luckily, your power doesn’t go out all that often anyway.
we have a power cut maybe every month.
