Make Your Smart Home Devices Work Together
A different app for the lights, the plugs, the camera and the thermostat? Here's how to bring them all into one place, so they work together and with your voice.
Pick one app to be the boss
Smart home chaos usually comes from having a different app for every brand. The fix is to choose one main platform, then connect everything to it:
- Apple Home, if your household uses iPhones.
- Google Home, if you use Android or Nest speakers.
- Amazon Alexa, if you have Echo speakers.
- Home Assistant, if you like tinkering and want everything local and private.
SET UPBring your devices together
Work through these once, in order.
List every smart device, its brand, and the app it uses. Check the box or the maker's website for these logos: Matter, Works with Apple Home, Works with Google Home, Works with Alexa. Devices with Matter can join any of the main platforms.
Pick the platform from above that suits your household, and make sure you have a hub for it, which keeps automations running when you're out:
- Apple Home: an Apple TV or HomePod.
- Google Home: a Nest Hub, Nest speaker or Google TV Streamer.
- Alexa: a recent Echo speaker.
Many of these also act as Thread border routers, which battery-powered Matter devices like sensors need.
In your main app, choose Add device (or Add Accessory) and scan the Matter QR code on the device or its box. Matter devices can be shared with a second platform later, so a light can work with both Apple Home and Alexa.
Devices without Matter can usually still be added by linking accounts. In Google Home or Alexa, add a device, choose Works with Google or Skills, find the brand, and sign in. They then appear alongside everything else. Apple Home only shows HomeKit or Matter devices, so check those first.
Use simple, unique names like “Kitchen light” and “Bedroom lamp”, and put each device in a room. Voice assistants get confused by duplicate or vague names, and clear rooms let you say “turn off the living room”.
Start small with automations that save real effort:
- Lights on at sunset, off at bedtime.
- Everything off when the last person leaves home.
- A “Good night” scene: lock doors, turn off lights, lower the thermostat.
If you have many brands, want automations that work without the internet, or care about privacy, Home Assistant is a free, open-source hub that connects thousands of device types and runs on a small computer at home. It takes more setup, but can still pass devices through to Apple, Google or Alexa for voice control.
Check the device has the latest firmware in its own app, and that your phone and devices are on the same Wi-Fi (2.4 GHz for many smart devices). Older devices with no Matter or platform support may need replacing eventually.
FAQCommon questions
What is Matter?
An industry standard that lets smart home devices from different brands work with Apple Home, Google Home, Alexa and others. A Matter device works with all of them.
What's Thread?
A low-power wireless network many Matter sensors and plugs use. It needs a Thread border router, which is built into many recent smart speakers, displays and streaming boxes.
Can I use Apple Home and Alexa at the same time?
Yes, for Matter devices. Add the device to one platform, then use its sharing or pairing mode option to add it to the other.
Do I need a hub?
For remote control and automations, yes, usually. Many smart speakers and streaming devices already work as hubs.
