To use Amazon Echo with a smart thermostat, you need to connect the thermostat to Alexa through the Alexa app, then use voice commands to adjust temperature, set schedules, and switch modes. For a more visual way to manage settings, you can also use Amazon Alexa smart speaker mode on a compatible tablet, which is perfect for when you want to play Amazon music on Alexa Echo in the background while adjusting your home's comfort. This process involves enabling the manufacturer's Alexa skill, linking your thermostat account, and discovering the device, after which you can control it hands-free with simple phrases like "Alexa, set the thermostat to 72 degrees."
What you need before you connect your Amazon Echo to a smart thermostat
Before you start, make sure you have the following ready:
- An Amazon Echo device (Echo Dot, Echo Show, Echo Plus, or any other Alexa-enabled speaker).
- The Amazon Alexa app installed on your smartphone or tablet.
- A smart thermostat that is already installed, powered on, and connected to your home's Wi-Fi network using its own manufacturer's app (e.g., Sensi, Nest, Ecobee, Honeywell Home).
- Both your Amazon Echo and your smart thermostat must be on the same Wi-Fi network for them to communicate.
If you haven't set up your smart thermostat yet, do that first using the dedicated app from its brand. This typically involves creating an account, connecting the thermostat to Wi-Fi, and configuring basic settings.
How to use Amazon Echo with a smart thermostat by enabling the Alexa skill
The first step to connect your thermostat to Alexa is to enable the correct skill in the Alexa app. A "skill" is like an app that lets Alexa talk to your thermostat's manufacturer. Here's how to do it:
- Open the Amazon Alexa app on your smartphone or tablet.
- Tap the menu icon (three horizontal lines) in the top left corner, then select Skills & Games (sometimes found under "More").
- Use the search bar to type in your thermostat's brand name, for example, "Sensi," "Google Nest," "ecobee," or "Honeywell Home."
- Select the correct skill from the search results.
- Tap Enable to Use or Enable Skill.
- You will be asked to log in with the same account you used for your thermostat's manufacturer app. Enter those credentials and allow the connection.
Once the skill is enabled and your accounts are linked, Alexa can now communicate with your thermostat. This linking step is essential, without it, Alexa won't be able to see or control the device.
How to discover your thermostat with Alexa
After enabling the skill and linking your account, you need to tell Alexa to find your thermostat. This is called "device discovery." Here's how:
- In the Alexa app, go to the Devices tab (the icon looks like a house).
- Tap the + icon in the top right corner, then select Add Device.
- Choose Thermostat from the list of device types, then select your thermostat's brand.
- Alternatively, you can simply say, "Alexa, discover devices" out loud. Alexa will scan your network for any new compatible devices.
- Wait a few seconds while Alexa searches. When it's done, you should see your thermostat appear in the device list.
To verify it worked, go to Devices > Thermostats in the Alexa app. Your thermostat should be listed there. If not, try saying "Alexa, discover devices" again or restart your Echo and thermostat.
Basic voice commands to control your thermostat
Once your thermostat is connected, you can start using voice commands right away. Here are the most common basic commands:
- "Alexa, set the thermostat to 72 degrees.", Sets a specific temperature.
- "Alexa, raise the thermostat by 2 degrees.", Increases the temperature by a set amount.
- "Alexa, lower the thermostat by 3 degrees.", Decreases the temperature by a set amount.
- "Alexa, turn on the thermostat.", Turns the thermostat on (if it was off).
- "Alexa, turn off the thermostat.", Turns the thermostat off completely.
- "Alexa, what's the current temperature?", Asks for the current temperature reading from the thermostat.
- "Alexa, what's the thermostat set to?", Tells you the current target temperature.
These commands work with most smart thermostats. If you have multiple thermostats, you can add the name you gave each one, for example, "Alexa, set the living room thermostat to 70 degrees."
Advanced voice commands for schedules and modes
Beyond basic temperature control, Alexa can handle more complex tasks like scheduling and switching modes. Try these advanced commands:
- "Alexa, set the thermostat to 70 degrees at 8:00 PM.", Schedules a temperature change for a specific time.
- "Alexa, set a heating schedule for weekdays.", Creates a recurring schedule for specific days.
- "Alexa, set the thermostat to cooling mode until 10:00 PM.", Switches to a specific mode (heating, cooling, auto) for a set duration.
- "Alexa, increase the temperature for 30 minutes.", Temporarily raises the temperature for a set period.
- "Alexa, what's the temperature in the living room?", If you have multiple thermostats, ask about a specific room or zone.
- "Alexa, set the thermostat to eco mode.", Activates an energy-saving mode if your thermostat supports it.
These commands give you more control over your home's climate without needing to touch the thermostat or open an app. Experiment with different phrasings, Alexa is flexible and will usually understand variations like "bump it up" or "make it cooler."
Special cases: Ecobee and Amazon Smart Thermostat
Some thermostats have unique setups you should know about:
Ecobee thermostats with built-in Alexa: Some Ecobee models (like the Ecobee SmartThermostat with voice control) have Alexa built directly into the thermostat. In this case, you don't need a separate Echo device to control it, you can talk to the thermostat itself. However, you can still connect it to your Echo devices for multi-room control. To set this up, follow the same skill-enabling steps in the Alexa app, but look for the "ecobee" skill specifically. Once linked, your Ecobee will appear as a thermostat in your Alexa device list, and you can control it from any Echo in your home.
Amazon Smart Thermostat: The Amazon Smart Thermostat is designed to work seamlessly with Alexa. Its setup is guided entirely through the Alexa app, there's no separate manufacturer app. When you install it, the Alexa app walks you through wiring, Wi-Fi connection, and initial configuration. During setup, you'll be asked whether you want Alexa to manage the temperature automatically (using smart features) or if you prefer to set a custom schedule. Once setup is complete, the thermostat appears in your Alexa device list automatically, and you can control it with all the standard voice commands. No extra skill or account linking is required.
If you have a different brand (like Nest, Honeywell, or Sensi), the process is the same as described earlier: enable the skill, link your account, and discover the device.
Remember to keep both your Echo and thermostat on the same Wi-Fi network, and check that your thermostat's firmware is up to date through its manufacturer app. If you run into issues, try disabling and re-enabling the skill, or restarting your Echo device.
By following these steps, you'll be able to use Amazon Echo with a smart thermostat for effortless, voice-controlled comfort in your home.
