Ecobee smart thermostats are one of the highest quality smart home products on the market, they offer many features like remote control capability, geofencing, learning cooling, and heating habits, energy savings, and much more.

The Ecobee thermostat has the ability to flash lights in different colors such as red, green, and blue, but what do those colors indicate?

In this article, we will discuss the meaning of each color and what to do when these colors appear on your device.

Why is my Ecobee blinking Green Light?

Ecobee thermostats work with the Alexa voice assistant, so when you get a notification, the thermostat will flash a green light telling you that you’ve received a notification.

So don’t worry too much about it, it’s just a kind of reminder in case you forget to check the notification.

To receive these types of alerts on your Ecobee thermostat, you need to activate the alert feature on your thermostat through the Alexa app or Alexa web portal.

The type of alerts you can receive depends on your choices when you turn this feature on in your Alexa app and you can change it whenever you want.

You can receive several types of alerts such as weather alerts, or Answers to your product questions on Amazon, or when a shipment has arrived, and much more.

How to stop the green light on the Ecobee thermostat?

As we say before Ecobee thermostat is integrated with Amazon Alexa, so if the green light really bothers you I can tell you that there are many solutions to stop it, so let’s dig in into these solutions:

  • Disable Amazon Alexa: To me, this solution is not the best one to choose because by disabling this option on your thermostat you’ll lose all Alexa features you can do on the device.

    Because many people use this voice assistant to control and manage their thermostats remotely through voice commands, like adjusting temperature, turning on and off ACs or heaters, and much more things.

    When you disable all Alexa features you’ll not be able to do these things.

    But if you want to disable it follow the next steps on the Ecobee app:
  1. Launch Ecobee App on your mobile.
  2. Tap the thermostat on the app screen.
  3. Tap the Microphone icon in the bottom-right corner of the screen.
  4. Select the Unlink Alexa at the bottom of the Audio screen.
  5. Confirm by selecting Unlink in the pop-up.
  • Ask Alexa notification: Since the green light is not a big issue and it doesn’t deserve to disable the Alexa feature for it, receiving the notification is the best thing to do to let the green light go.

    All you have to do is to be close to the thermostat or your Echo Dot and say “Alexa read me my notifications.” or “Alexa what are my notifications?” then Alexa will read you your notifications then the green light will disappear.

    You can also do it manually by checking and deleting the notification from the mobile app.
  • Modify the notifications settings: You may have chosen to receive a lot of notifications on your Ecobee thermostat when enabling the Alexa feature so you have your thermostat flashing green every hour and you find that annoying.

    You can easily go to the Alexa app and choose which notification you want to receive, to do that follow the next steps:
  1. Go to the Amazon Alexa app.
  2. Click the More icon.
  3. Select the settings option.
  4. Select “Notifications”.
  5. Then you’ll get a menu where you can choose the type of notifications you want to receive, or you can disable all the notifications.
  • Do not disturb mode: Another solution for this problem is to activate the “Do Not Disturb Mode” to allow Alexa to send you alerts on the thermostat during certain periods.

    You can easily activate this mode on the Alexa app, to do it follow the next commands:
  1. Go to settings.
  2. Choose the Ecobee device.
  3. select “Do Not Disturb Mode”
  4. Then choose “Do Not Disturb” permanently or create a Scheduled option.
  • Reboot the Ecobee Thermostat: generally speaking, the solutions cited before will turn off your green lights, but just in case the previous methods don’t work you can try to reboot your device.

    To reboot your Ecobee Remove it from its wall housing, then Leave it removed from the wall for around one minute before placing it back.

    One of the advantages of rebooting is that it will fix the problem without removing any of your settings.
  • Reset your Ecobee thermostat: If the reboot option also doesn’t fix the issue, you can go and reset all device, and here’s how to do it:
  1. Go to the Main Menu on the thermostat screen.
  2. Select the Settings.
  3. Then select the Reset menu.
  4. Select the option labeled Reset All.

    Your Ecobee will now restore itself back to the default factory settings and the green lights flashed by the thermostat will go away.

Why is my Ecobee blinking blue Light?

Ecobee blue light

Some Ecobee thermostats like Ecobee4 have a built-in microphone, so you can talk with Alexa through your thermostat and you’ll not need to purchase the Amazon Echo Dot because you will be able to do everything from the Ecobee device, simply put use it as your smart speaker.

And this is the origin of the blue light on your thermostat, when you say the wake word like “Hey Alexa”, to give a command like “set the temperature at 72 degrees” or ask it some questions or get the weather forecast or whatever.

The device will flash the blue light that’s mean it’s listening to you and waiting for your command the same thing as your Echo smart speaker.

If you want to deactivate this light permanently, you have to turn off the microphone that means you’ll not use this feature at all.

follow the next steps to turn off the microphone option:

  1. Go to your thermostat screen.
  2. tap the microphone icon at the bottom right of the screen.
  3. on the voice control screen you can switch off the microphone.

Why is my Ecobee blinking red Light?

As a result of disabling the microphone on the Ecobee thermostat, a red light will flash, which means the microphone has been turned off and you cannot use it to talk to Alexa and manage other devices or ask questions from the thermostat.

The feature can be useful if you only want to rely on your Echo Dot or other Alexa-enabled devices, or when your Ecobee device is placed in a noisy area like the living room.

The only way to restore the functionality of the microphones is to activate it from the mobile app or from the thermostat screen and I have already shown you how to do this.


Finally, if you fix all the issues and there’s no light coming from the Ecobee thermostat that means that your device is working correctly and has no notification or alerts to show it to you.

It’s essential to understand the light’s colors meaning to be able to know the source of the issue and troubleshoot the device yourself without relying on any person.
