How to use Alexa to turn on the light



The use of smart home technology is one of the more attractive promises of voice control systems like Alexa. It is tempting (and perhaps inevitable) to overthrow a complex rabbit hole when setting up a smart home, as there are so many options and options. If you're just getting started, it may be a good idea to keep it simple for your first step in creating a smart home. For example, let's start by installing a single light bulb that Alexa can turn on and off for you.

There are many brands of smart bulbs, so the setup procedures can vary from brand to brand. I have chosen a Philips Hue light bulb as it is readily available, quick to set up and well supported.

Initial setup

The first step is to screw in the light bulb (insert a joke here) and the first thing to check is whether the lamp is on a dimmer. Many lamps use dimmers, but older dimmers can not meet the current requirements of LED lamps. You can think about it when you go into more detail about smart home setups. Avoid dimmers for the time being. Ready?

  • Open the Alexa app on your phone, turn on the light and wait a few seconds.
  • Tap the Devices tab in the lower-right corner of your screen.
  • At the top of the device screen there are some buttons. On the first page is "Echo & Alexa" and on the last page "All Devices". If you are lucky, you will also see a "Lights" button between them. Tap on it, because that means that Alexa has installed her luminaire by herself. You can now move to the Final Setup section of this article.


Adding a device manually

If you're not so lucky, you'll need to set up a little.

  • At the top right of the Devices screen, tap the plus sign and then tap Add Device in the menu that appears. Above are buttons for some popular device brands and protocols.
  • If you are not there, tap "Light" and then tap the mark of the light you want to install. You may need to download another app and perform an installation at this point. Follow these instructions carefully.


  • If your light bulb is one of the popular brands near the top of the Add Device setup screen (for example, my Philips Hue bulb was there), it makes things a little easier.
  • Tap the corresponding icon to go to the setup screen. At this point, I was asked if the bulb is Bluetooth enabled. Newer Hue bulbs are Bluetooth enabled from the second half of 2019 and have the Bluetooth logo on the lamp and the box. If you have an older Hue bulb, you may need to install the hardware bridge that was probably supplied with the bulb. Follow the instructions in the Alexa app by downloading a hue app to your phone and installing a hue capability on the Alexa. That is, unless you have an Echo Plus, an Echo Show or an Echo Studio. In that case you should not have any problems. These models feature built-in ZigBee hubs that connect directly to Hue and other lamps.


  • If you have a newer Bluetooth lamp, make sure your echo software is up to date by asking, "Alexa, is your software up-to-date? "If not, ask him to update himself.
  • If you're sure your software is up to date, turn the Hue light off and on again. Then press the "Discover Devices" button at the bottom of the setup screen.
  • The lamp may be flashing. The app should display a screen indicating that it is connecting to the light bulb via Bluetooth. If the process fails, just try again.
  • When it finally works, a screen will appear informing you that a light has been detected. Touch the device setup button and you'll be alerted that the light is set and ready for use. Touch Done.


End result

If you now tap this "Lights" button, you will see a list of all the smart lights that you have set up to work with Alexa. Touch the name of the light and you will see a screen where you can adjust the brightness with a slider. In the top right corner is a gear icon that opens a light bulb information screen that allows you to rename the device.



To turn the light bulb on and off, you can simply say, "Alexa, turn on " or "Alexa turn off ". You can also dim them: "Alexa, dim 50 percent."
