If you have an Amazon Echo, you’re probably keen to use Alexa for more than just weather forecasts and setting timers. With inexpensive hardware you can get Alexa to turn individual or groups of lights on and off, and by using Routines you can make them turn on automatically at set times.
What is needed to control lights with Alexa?
- Smart plug, or
- Smart light bulb, or
- Smart wall switch
- A device with Alexa built-in or the Alexa app
You need at least one piece of hardware from this list that is compatible with Alexa before you can control a light, plus the latest version of the Alexa app and / or an Amazon Echo or another device that has Alexa built in.
Alexa works with many smart bulbs including Philips Hue and LIFX bulbs.We’re big fans of these because they’re high quality, reliable and offer lots of features. They come in white and colour versions, with the latter costing more, but still able to produce good whites as well as bright colours.
However, even the cheapest Wi-Fi bulbs can be expensive, so if you don’t want to splash out on new lights, you can instead buy smart switches that are compatible with Alexa.
Amazon now sells its own smart plug for £24.99 / $24.99, which isn’t the cheapest option either, but it couldn’t be easier to use and doesn’t require you to add a new Alexa skill or create yet another user account.
Obviously this is no good for ceiling lights as it will only turn on and off lamps which plug into a mains socket.
But you can get Alexa-compatible wall switches These include Lightwave RF and Energenie MiHome. Note that – like Philips Hue – these both require a ‘hub’ which plugs into your router: they don’t talk directly to it using Wi-Fi.
Whichever method you use, the way to control compatible lights, plugs and switches with Alexa is the same. Here’s how to do it.
How do you turn Alexa lights on?
To get started, you need the Alexa app. It is available on , and Amazon Fire tablets. You’ll probably have the app already if you have an Amazon Echo.
Before you can turn a light on, you must install and set up your light bulb, plug or switch. Do this by opening the Alexa app and following these steps:
- Tap on Devices at the bottom right
- Now tap on the + icon at the top right
- Select the type of device you are setting up (Light, Plug or Switch)
- Choose the brand from the list
- Follow the instructions on screen
Typically, you will have to create an account with the manufacturer of the hardware, then link that account with your Amazon account and authorise the app to use that account.
Once your plug, switch or light is set up you should be able to see it when you tap on Lights, Plugs or Switches on the Devices screen in the Alexa app.
You will want to rename it with a friendly name that’s easy to remember, and which Alexa can easily understand. Do this by tapping on the device in the list, then tap on the cog icon (top right) and then tap Edit name. Just like this:
It’s best to use short, single-word names, but you can experiment and change the name if it isn’t understood by Alexa.
To turn on a light with Alexa, the simplest command is:
- “Alexa, turn on [name of light]”
If your light or switch supports dimming or changing colours, you can also say:
- “Alexa, make the front light purple”
- “Alexa, dim the living room”
- “Alexa, make the kitchen brighter”
How do I control groups of lights with Alexa?
- Go to Devices in the Alexa app
- Tap the + icon, top right
- Tap Add group
- Pick from the pre-defined names or add a customised name for the group
- Tap on the devices you want to be in the group
- Tap SAVE
You can add an Amazon Echo device to the group as well. This is very useful if you have more than one Echo as it allow you to – for example – walk into the living room and say “Alexa, turn on the lights” and she will understand what you mean because you have grouped the Echo in that room with the smart bulbs in that same room.
Once this is done, you can say, “Alexa, turn on Dining Room” and all devices in that group will be switched on.
In case you need to, here’s how to update your Echo’s software.
