Thermostats from Ecobee are among the most intelligent options for controlling the temperature in your house.

These programmable, energy-efficient gadgets can help you reach maximum energy efficiency.

However, they can also beep or make random noises for no apparent reason, as can all other devices.

Why is this occurring?

The chirping of an Ecobee thermostat is likely due to unread notifications from Alexa or a comparable app. Reading or deleting the notification is the most effective way to eliminate the disturbance. If the sound persists, it may be due to electrical problems or originate from sources external to the thermostat.

The remainder of this article examines in greater detail why an Ecobee thermostat will emit beeping sounds.

What exactly is an Ecobee thermostat?

An ecobee thermostat is a smart thermostat manufactured by the Canadian home automation company Ecobee.

These thermostats assist maintain the appropriate temperature in your home at all times.

If you install one of these, you can control it via your mobile device or the touchscreen display.

There is also a web portal that you can access when you are not near your mobile phone.

You can control the temperature of your home with an ecobee thermostat from anywhere in the world, provided that the thermostat is properly configured and connected to the internet.

Why Does My Ecobee Chirp?

If you hear regular beeping coming from the direction of your ecobee, you should first verify that the thermostat has been installed in accordance with the manufacturer’s recommendations.

Examine the following:

  • Is it correctly linked to your residence’s Wi-Fi?
  • Does the app display any error messages?

If everything is in order, the next step is to examine the installed applications. Perhaps one of them is attempting to communicate.

For example, Alexa is a frequent offender in this regard. The program will leave a blinking light, a bubble on the thermostat’s display, and a beeping sound when messages are received.

Depending on the model of Ecobee thermostat you have, the noise may be intermittent and simple to ignore, or it may be quite consistent and annoying.

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

Typically, you can only delete from the Alexa app on your mobile device by issuing a voice command. Simply issue a command like as “Delete all of my notifications”

If you prefer to read the alerts first, you can alternatively use one of the following primary commands:

  • “Check out my Notifications.”
  • “What did I overlook?”

And to advance to the next notice, simply say “Next” or “Previous” as appropriate.

After the beeping has ceased, the best course of action is to disable all notifications, as the vast majority of them will be irrelevant to you.

Here are the steps to accomplish this:

  1. Launch the Alexa App
  2. Navigate to “Settings”
  3. Navigate to “Devices” and locate your ecobee name.
  4. Change the settings for notifications to “Do Not Disturb” or make a schedule for when you’re available to receive them.

Here is a list of additional Alexa commands that can be used to control the app more effectively.

Alexa is highlighted because the majority of buzzer sound disturbances on an Ecobee begin after Alexa activation. It is a voice assistant that can perform a multitude of tasks.

Unfortunately, it is not always uncomplicated to control.

If you have installed additional voice assistants on the thermostat, removing the beeping sound will follow a similar path to what we’ve seen before.

Eliminate all notifications, and the beeping will likely cease.

What happens if the beeping persists?

At this time, you should search for further potential causes of the beeping sound.

Carbon monoxide detectors and smoke alarms are the most likely sources of beeping sounds that you may mistakenly ascribe to your Ecobee.

If these are in the same room as the thermostat, move closer to establish that neither is the source of the beeping sound.

Ecobee must be reset if the sound is not coming from either of the two sensors.

Why Is My Ecobee Noisy?

Your Ecobee may produce sounds other than beeping. You may also hear the following forms of noise emanating from it:

Clicking Sounds

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

A “dead” thermostat that would not switch on is typically accompanied by a clicking sound.

It indicates insufficient voltage between the C and RC terminals, which can be traced to an improperly connected C wire or a faulty C wire on the side of the HVAC equipment.

Here is what you can do to fix the issue:

  • Use a different wire in place of the C wire, ensuring that it is linked to the C terminal on both the HVAC equipment and the ecobee.
  • If you cannot repurpose another wire to replace the faulty C wire, consider adding a Power Extender Kit or running more wires.
  • If your C wire is a repurposed spare wire, verify that it connects to the C connection point on your HVAC unit.

Dual-Tone Warnings

Do you occasionally receive a dual-tone alarm and flashing lights from your Ecobee?

If your ecobee emits a dual-tone signal at varying intervals, this could indicate a connection issue.

Verify that the device is linked to the Internet at home.

Some users have claimed that rebooting their router resolved this issue.

Restarting the router and the device at the same time can automatically resolve connectivity issues for the vast majority of devices, including your ecobee.

Single Tone Alerts

Some Ecobee users have reported hearing numerous single-tone notifications that persisted until the thermostat received an update.

If you are experiencing similar issues, your firmware may be outdated.

Each Ecobee device is programmed to update itself automatically.

Once a firmware update becomes available, the system will automatically download and install it without your intervention.

If you are unsure if you have the most recent firmware update, check the Ecobee support website for the most recent information. Compare the most recent version to the one you have.

If they are identical, then the error rests elsewhere. If there is a difference, some troubleshooting will be required.

To verify your firmware, follow these steps:

Turn on the thermostat’s user interface.

Proceed to the main menu.

Select “About” from the menu.

The version of the Ecobee firmware should be included.

After confirming an inconsistency in the Ecobee firmware, the next step is to await an update.

There is no method to force the update, so all you can do is confirm that your internet connection is functioning properly.

If the internet connection is enough, the update will be installed automatically a few weeks after its first release, if the internet connection is stable.

After a couple of weeks have passed after you reset your internet and the update still hasn’t arrived, it’s time to contact Ecobee’s customer service. They can push the update manually.

If the update does not resolve the noise issue, they will assist you in resolving it.


The beeping of an Ecobee thermostat indicates that you have unread notifications.

If you delete these notifications and prevent them from arriving, the issue will likely disappear.

Alexa is typically at fault, but if you haven’t activated it, examine other installed apps.

In some situations, a firmware upgrade is sufficient.

After trying everything and the thermostat continues to make noise, it is necessary to contact the ecobee help desk.

If they are unable to resolve the issue, they will suggest purchasing a new product.
