A smart home device works with Alexa in one of three ways: through the maker's own Alexa skill over Wi-Fi, through Matter, or by connecting directly to an Echo that has a built-in smart home hub (Zigbee, or Thread for Matter devices). The route decides what you need. A skill needs the maker's app and account; Matter and Zigbee need the right Echo. Before you buy, check the box for the "Works with Alexa" badge or the Matter logo, then check whether your Echo can be the hub.

The ways a device connects to Alexa
| Route | What you need | What Amazon says |
|---|---|---|
| The maker's skill (cloud) | The maker's app and account, plus its skill enabled in the Alexa app | Makers can "build an Alexa smart home add-on to control your cloud-connected devices over Wi-Fi." |
| Matter | A Matter-enabled Echo; for Matter over Thread, a Thread-enabled one | "With Matter, smart home devices can connect directly to Alexa without a separate hub or smart home add-on." |
| Zigbee | An Echo with a built-in hub, or a separate Zigbee hub | "Amazon Echo and eero devices have built-in smart home hubs that seamlessly connect and control Zigbee smart devices." |
The local routes have one advantage and one catch. Amazon says a local connection between an Echo and a device lets voice control work "even when the internet or cloud infrastructure is down." But it also says "device capabilities for BLE-mesh and Zigbee-enabled devices are limited to basic functionality, such as power on and off," while "Matter over Wi-Fi and Matter over Thread support many more device capabilities." In practice, a Zigbee bulb paired to an Echo may give you on and off by voice but not every feature its own hub or app offers.
What the "Works with Alexa" badge means
Works with Alexa is Amazon's certification program, which "verifies smart home products for responsiveness, functionality, and compatibility with Alexa." Amazon says it "uses an independent, third-party testing facility" for the tests.
The badge is optional, and that matters when you read a box. A maker that skips the program cannot use the badge, but Amazon allows it to use the phrase "Compatible with Alexa" in plain text. So the badge means the product went through Amazon's testing; the plain-text phrase is the maker's own claim. Both can work fine. Only one has been checked by someone other than the maker.
Does your Echo have a hub?
This is the question that decides whether a Zigbee or Thread device will work without buying anything else. Amazon's own shortcut: "If you're not sure if your Echo device has a hub, ask Alexa. Say, 'Do you have a smart home hub?'" Amazon also lists the models in its developer documentation for Zigbee, Matter and Thread.
- Zigbee: check for a Zigbee logo on the device, and Amazon says to "install your smart home device within 30 ft (9 m) of your Echo device with a built-in hub." If your Echo has no hub, "you can connect your smart home device through a separate Zigbee hub."
- Matter: "Matter-compatible Echo devices support the Matter 1.5 Software Development Kit (SDK), enabling support for a subset of Matter 1.5 and lower device types." In other words, not every Matter device type works with Alexa yet; see the list below.
- Thread: Thread-based Matter devices need a Thread border router in the house. Some Echo models are one; so are some Apple, Google and eero devices, listed in our guide to Matter over Thread smart plugs.
- Z-Wave: Amazon's buying guide says "Zigbee and Z-Wave devices usually need a hub" and that "many Echo devices have built-in Zigbee hubs." It says nothing similar about Z-Wave, so plan on a separate Z-Wave hub.
What works with Alexa over Matter
Amazon's list of Matter categories reads: "Alexa supports many device types from the following Matter device categories, Matter hubs, lighting and smart plugs, generic buttons, sensors, closure devices (door locks, window coverings), thermostats, fans, air purifiers, appliances (room air conditioners, dishwashers), and robotic vacuums."
Two gaps are worth knowing. Cameras and video doorbells are not on that list; Google's Nest cameras, for example, reach Alexa through a skill (below). And the list says nothing about energy readings from smart plugs, so do not count on seeing a plug's power data in Alexa. Our smart plug guide has a table of which apps do show it.
Will Alexa work with Nest?
Yes, through a skill. Google says "Google offers a Smart Home skill to connect your Nest devices to Alexa home control," covering Nest cameras, doorbells and thermostats, and that the skill "is only available to users with a Google Account." The limits Google lists:
- "Some Google Nest features can't be controlled by Alexa."
- Alexa cannot control a Nest thermostat when it is set to an Eco Temperature, in Off mode, using Emergency Heat, or after an Emergency Shutoff.
- Seeing a Nest camera's live view "only works on Alexa devices that have a display," so an Echo Show, not an Echo Dot.
Before you buy: a short checklist
- Read the box for the route. "Works with Alexa" badge (tested by Amazon's program), "Compatible with Alexa" in plain text (the maker's claim), or the Matter logo (works with Alexa if its category is on Amazon's list).
- Check the Wi-Fi band. Amazon notes that "most smart home Wi-Fi devices only work on 2.4GHz bands." If your router merges its bands under one name, our guide to choosing a router for a smart home explains what to change.
- For Zigbee or Thread devices, check your Echo first. Ask it whether it has a smart home hub before buying a separate one.
- If anyone in the house uses Google Home or Apple Home too, Matter is the route that lets the same device work in more than one app.
To add a device, Amazon's steps are: "Open the Alexa app. Open Devices. Select the plus icon. Select Add Device." Then pick the device type and brand.
