Why Is My Ecobee Thermostat Beeping? Reasons + Solutions

Why Is Your Ecobee Thermostat Beeping

Ecobee thermostats are one of the best smart solutions for controlling the temperature in your home.

These efficient, programmable products can help you achieve optimal energy efficiency.

However, like all others, they can also beep or make random noises for no apparent reason.

Why does this happen?

An Ecobee thermostat beeping is likely due to unread notifications from Alexa or a similar app. Reading or deleting the notification is the best way to get rid of the noise. If the sound persists, it may be due to electrical faults or coming from external sources outside the thermostat.

The rest of the article will take a closer look at why an Ecobee thermostat will make beeping sounds.

What’s an Ecobee Thermostat?

An ecobee thermostat is one of the various smart thermostats made by the Canadian home automation brand Ecobee.

These thermostats help maintain the optimal temperature in your home at all times. 

If you install one of these, you can control it from your mobile phone or the built-in touchscreen.

There’s also a web portal you can log on to when you’re far away from your mobile phone. 

With an ecobee thermostat, you can control your home’s temperature from anywhere in the world – as long as the thermostat is properly set up and connected to the web.

Why Is My Ecobee Beeping?

If you hear regular beeping coming from the direction of your ecobee, the first thing you should do is to confirm that you’ve set up the thermostat completely in line with the manufacturer’s instructions. 

Check the following:

  • Is it properly connected to your home Wi-Fi? 
  • Are you getting any error messages on the app?

If everything checks out, the next step is to look at the installed apps. One of them might be trying to communicate. 

For instance, Alexa is a common culprit in this regard. Messages on the app will leave a blinking light, a bubble on the thermostat screen, and a beeping sound.

Depending on your model of Ecobee thermostat, the sound may be intermittent and easy to ignore or very regular and frustrating.

If the message notification is the problem, the immediate solution is to delete the messages.

In most cases, you can only delete from the Alexa app on your mobile by giving a voice command to that effect. All you need is a command like:

  • “Delete all of my notifications.”

If you’d like to read the notifications first, you can also go with any of the main commands:

  • “Read my Notifications.”
  • “What did I miss?”

And if you want to move to the next notification, just say “Next” or “Previous” as the case may be.

Most of the notifications will be pointless to you overall, so the best thing to do after the beeping has stopped is to turn off the notifications completely.

Here are the steps on how you can do this:

  1. Open the Alexa App
  2. Go to “Settings”
  3. Go to “Devices” and find your ecobee name
  4. Change the notifications settings to “Do Not Disturb” or create a schedule of when you’re open to notifications.

Here’s a list of other Alexa commands that can help you control the app better.

Alexa is the focus here because most beeping sound disturbances on an Ecobee start after Alexa is activated. It’s a voice assistant that can do a ton of things. 

Unfortunately, controlling it isn’t always straightforward.

If you’ve installed any other voice assistants on the thermostat, the pattern for getting rid of the beeping sound will be similar to what we’ve seen above.

Get rid of all the notifications, and the beeping sound will likely stop.

What if the beeping continues? 

At this point, you should look around for other possible sources of the beeping sound.

Your carbon monoxide detector and smoke alarm are the two prime suspects for beeping sounds you may unknowingly attribute to your Ecobee.

If these are in the same room as the thermostat, go closer and confirm that the beeping sound isn’t coming from either of the two.

If the sound isn’t coming from either of the two, it’s time to reset your Ecobee.

Why Does My Ecobee Make Noise?

Your Ecobee can make more than just beeping sounds. You may hear other types of persistent noise coming from it, including:

Clicking Sounds

Ecobee Makes Noises

This is a common issue with some Ecobee models (not including the Smart SI and Smart variants). 

The clicking sound often accompanies a “dead” thermostat that won’t turn on.

It is a sign of insufficient voltage between the C and RC terminals, which can be traced to a C wire or a bad C wire, which isn’t connected properly to the side of the HVAC equipment. 

Here’s what you can do to correct the problem:

  • Get another wire to use in place of the C wire, making sure it is connected to C at both the HVAC equipment and the ecobee.
  • Repurpose another wire as C.
  • Consider installing a Power Extender Kit or running additional wires if you can’t repurpose another wire to replace the bad C wire.
  • If your C wire is a repurposed spare wire, confirm that the wire also connects to the C connection point at your HVAC unit.

Dual-Tone Alerts

Are you getting a dual-tone alert and flashing lights occasionally from your Ecobee?

If you hear a dual-tone alert at different intervals from your ecobee, it could be a sign of a connection problem.

Check to see that the device is connected to your home internet.

Some people have reported resolving this problem by restarting their router.

Restarting both the router and the device at the same time can automatically solve any connection problem for most devices – your ecobee included.

Single Tone Alerts

Some people have noted hearing frequent single tone alerts from their Ecobee that didn’t go away until the thermostat received an update.

If you’re facing similar problems, your firmware may be out of date.

All Ecobee devices are designed to update automatically.

Once there’s an update available, the system will automatically download and install the firmware update without any interference from you.

If you’re not sure you’ve got the latest firmware update, check the Ecobee support page for the latest data. Compare the latest version to what you’ve got. 

If they are the same, the fault lies elsewhere. If there’s a difference, you’ll have to do a little troubleshooting.

To confirm your firmware, here are the steps:

  1. Turn on the interface on your thermostat.
  2. Navigate to the main menu.
  3. Select the “About” option.
  4. The ecobee firmware version should be there.

When you’ve confirmed a disparity in the Ecobee firmware, the next step is to wait for an update.

There’s no way to force the update, so all you can do is check your internet connection and ensure there are no problems there.

If the internet connection is fine, the update will get installed automatically within a couple of weeks from when it was first released. 

After you’ve waited a couple of weeks from resetting your internet and the update still hasn’t arrived, it’s time to contact the Ecobee support team. They can manually push the update.

If the update doesn’t solve the noise problem, you can get them to help you fix it.


A beeping ecobee thermostat is often a pointer that you’ve got unread notifications.

If you clear those notifications and stop them from coming in, the problem will most likely go away.

Alexa is usually at fault here, but if you don’t have it activated, check other apps you’ve installed.

In some cases, all you need is a firmware update.

After you’ve tried everything and the noise continues to come from the thermostat, it’s time to contact the ecobee support desk.

If they can’t solve the problem, they’ll recommend getting a new product.
