How to connect Alexa to lights

One of the most useful features of Alexa is her ability to control the lights in your home. Being able to say, “Hey Alexa, turn on the living room lights,” is a tremendously useful trait. It’s one of the first things that make a home feel truly “smart.” The good news is that connecting lights to Alexa isn’t hard — especially if they’re automatically compatible with the voice assistant. Here’s how to get started.

Alexa makes it easy to connect to the smart lights in your home. As an example, we will walk step by step through connecting Philips Hue lights to your Alexa smart assistant.

First, download the relevant app. In this case, the Philips Hue app. You’ll need to create an account and set up the lights through the Hue app first.

Once you set up the lights on the Philips Hue app, open the Alexa app. Tap the series of Three Bars on the bottom-right corner of the screen that says More. On the next screen, tap Add a Device. You’ll be prompted to select a type of device from the list. You can manually scroll through the options until you find what you’re looking for, or you can type “Philips Hue” (or whatever kind of lights you use) into the search bar. Next, tap Search for Devices. When you find your device, select it and tap Set up Device.

Keep in mind that some devices, including Philips Hue, use a Wi-Fi bridge that needs to be connected to your router through an Ethernet cord to work. If you haven’t connected your Hue Bridge, your lights will not appear on the list.

Now, you’ll have the option to add the device to a specific room in the home. If you have already set up Groups within the Alexa app, select the appropriate one for your lights and tap Continue.

That’s all there is to it, really. Any compatible light can be connected to Alexa this way. In many instances, Alexa will prompt you to connect lights when it detects any on your network. However, if lights aren’t automatically compatible, you might have to jump through more hoops in order to make them work.

Controlling your lights through Alexa

Smart lights are capable of performing a variety of tasks. Once you have your lights set up, you can adjust their brightness, change the color, and much more with nothing more than your voice. A few examples of what you can say include:

  • “Hey Alexa, set living room lights to 50 percent.”
  • “Hey Alexa, turn off bedroom lights.”
  • “Hey Alexa, turn the entryway light green.”

If you don’t have colored lights, you will only be able to adjust the color temperature of the lights. You can also connect the lights to music, sync them with your television or video game system, and much more. Once you learn how to connect your lights, you can experience one of the most useful parts of the smart home with a simple Alexa command.

Can you use a Blink Outdoor Camera without a subscription?

For security and peace of mind around your home, a Blink Outdoor Camera is one of the most popular choices for keeping an eye on your property. The outdoor cameras have features like motion detection, a Live View which lets you see what is going on at your property right from your smartphone, and an Activity Zones option that lets you choose which areas of your property you want to record -- which is handy if you live near a busy street where cars could constantly set off annoying motion detection notifications. The recently released Blink Outdoor 4 has improved on these features to make them even better than the previous Blink Outdoor 3.

Like most home security systems, Blink operates on a subscription plan, with a monthly charge starting at $3 to use the service. But if you don't want to pay for the charge, you might want to try using the cameras without the subscription -- though there will be some severe limitations if you do.

Can Alexa call 911? How to set up Alexa for emergencies

If you've got an Alexa in your home, you can use it for more than just alarms and playing music. The device can help out in an emergency, allowing you to get in contact with help if there's an unexpected crisis. In 2023, Amazon announced it was adding an Emergency Assist feature to the device, which is a paid service to help a user connect to an agent who will call 911 for them. The device can't call 911 directly, but it can put you in touch with someone who can call on your behalf and give out key information to emergency responders.

If you don't want to try Emergency Assist, you can also try setting up an Echo Connect box to your landline (if you can find one, as these products are no longer available) to call for you, or using an Alexa skill like Ask My Buddy. There are also other security features you might want to try out on your Alexa like Alexa Together, a subscription for assistance for older adults.

While there are some aspects that are hard to automate (such as chemical treatments or maintaining pumps and skimmers), you can delegate vacuuming to a reliable robot assistant.

Built to run autonomously after a brief setup, pool robot vacuums will suck up all the dirt and debris lingering in the water. Most can run for over an hour before needing to be recharged or come with a wired connection for constant use. All of them are equipped with a variety of filters and scrubbers, ensuring your pool looks pristine the next time you go for a swim.
