Wi-Fi: FAQ, Setup Guide, and Troubleshooting

This article applies to all ecobee thermostats except Smart, Smart SI, EMS and EMS SI. For connection issues with your Switch +, please visit our Switch + Wi-Fi troubleshooting article. 


The short answer is yes.

Even without a Wi-Fi connection, your ecobee will still function as a traditional thermostat; it will engage your equipment as needed and maintain your comfort set points.

You can simply skip the Wi-Fi Configuration portion when setting up your ecobee, though please be advised that skipping this step and never connecting your ecobee to Wi-Fi will not allow you to complete the registration process, so you will be unable to create an ecobee account.

In the event that you require assistance from our Support team, without a registered ecobee account with sufficient data, our Support team will be quite limited in the assistance they can provide, so we recommend initially connecting to Wi-Fi to at least register your thermostat.

After you've registered your thermostat, if you choose to proceed without a Wi-Fi connection, you will lose some of the ecobee's most useful features such as:

Remote access through the mobile app and Web Portal

You will not be able to check the status of your thermostat or make any changes through the mobile app or Web Portal.


Your thermostat will not have access to any weather data. If your home has a heat pump system, the ecobee relies on weather data to determine if it's safe to run your compressor.

Home IQ

To generate Home IQ and System Monitor reports, your thermostat needs to be online and communicating with our servers, so you will not receive any efficiency reports or have access to any runtime data.

HomeKit, Alexa, and other APIs

Since HomeKit (Siri) and Alexa require a stable Wi-Fi connection (as do all other apps such as IFTTT, Wink, SmartThings), you will not be able to utilize any of these features.

Pairing a SmartSensor 

To pair an ecobee SmartSensor to a thermostat, you will need to have the thermostat and your ecobee app on the same Wi-Fi connection. To know more about how to pair a SmartSensor to your thermostat, visit our general FAQ article.

Knowing your thermostat's network information is useful in identifying Wi-Fi issues and when troubleshooting with our technical support team.

1. On your thermostat, go to the MAIN MENU > ABOUT

On top of your network information, you can also view your the status of your thermostat's connection to your Wi-Fi router as well as to the server. Your Wi-Fi signal strength can also be found here – this information is useful in identifying dropped connections as well as Alexa command issues.

ecobee is committed to protecting our customer’s privacy.

We support WPA/WPA2-AES security for connecting to Wi-Fi networks.

Once the ecobee thermostat has joined the Wi-Fi network, it initiates an encrypted TLS connection to ecobee's servers. This TLS connection is authenticated using certificates, and provides privacy and data integrity to the underlying communication channel.

The security model of the thermostat is one in which the device itself always initiates connections to ecobee’s servers—no incoming connections from the internet are permitted to the device.

ecobee products and services use an SSL connection to ensure the highest level of security. The SSL protocol is commonly utilized by banks, government agencies, and e-commerce sites to ensure privacy and the protection of personal information.

2. On this screen, make sure Wi-Fi Radio is Enabled and tap on Network.


3. You will have the choice of using an iOS device or manually selecting your Wi-Fi network. If you do not have an iOS device, tap on Select Wi-Fi Network.


5. Find your Wi-Fi name on the list provided. If are installing an ecobee3, ecobee3 lite, or an ecobee4 and you have a dual-band network, be sure to select the 2.4Ghz network from the list. This condition will not apply to the SmartThermostat with Voice as this model is dual-band compatible.


6. Type in your Wi-Fi Password and hit Connect.


7. Wait for the ecobee to show the success message and hit OK to finish the process.


Using an iOS device to connect your thermostat makes for a fast an easy set up that eliminates the need of typing in your Wi-Fi password. All you need is an iOS device (iPhone, iPad, or iTouch) that is connected to a compatible Wi-Fi network. Follow the steps provided to get started:

1. Go to Main Menu > Settings > Wi-Fi

The ecobee thermostat will now connect to your Wi-Fi network and will display a “Successfully connected to” message upon completion. Tap “OK” in the bottom right corner on the ecobee thermostat screen.



If you are having issues with Wi-Fi or are in the middle of setting up your thermostat for the first time, here are a few things to consider:

1. Ensure your router is powered on and is broadcasting on a 2.4 GHz network. If you have a dual-band router, you’ll want to make sure to connect to the 2.4 GHz band—not the 5GHz band.

UPDATE: This consideration doesn't apply to SmartThermostat with Voice Control as it is dual-band compatible (i.e. supports connections on both the 2.4 GHz and 5 GHz bands).

2. Ensure your firmware is up-to-date by going into Main Menu > About > Version on your thermostat.

3. Check your router and ensure that your encryption type is set to WPA/WPA2-AES. We recently updated our security protocols removing support for TKIP encryption, so you may need to update your router settings.

4. If your thermostat is already connected previously, check the signal strength on the ecobee by going into the Main Menu > About > Wi-Fi on your thermostat. A signal strength lower than 75% could account for connection issues.

Connection issues can be caused by a number of things. Try the steps below to troubleshoot the issue:

1. Try power-cycling the ecobee and the router by unplugging the router and removing the ecobee from the wall.

2. Leave both the router and the ecobee off for about two minutes, then plug the router back in first.

3. Once the router is back up and running, place the ecobee back on the wall and wait for it to finish powering up—it should reconnect to Wi-Fi on its own.

You can check the status of your connection on your thermostat's screen by going into the MAIN MENU > ABOUT > WI-FI. You’ll want to make sure your ecobee is connected to your router, as well as connected to the servers.

4. An older firmware version may also cause connection issues. Check your thermostat's firmware version by going to MAIN MENU > ABOUT > VERSION. Visit our article on the latest thermostat firmware version to know if your thermostat is up-to-date.

If you’re on an older firmware version, reach out to our Support team (1-877-932-6233) and request an upgrade.

5. If your Wi-Fi signal strength is low, consider moving the router closer to the ecobee (if possible) or looking into a Wi-Fi range extender to provide a stronger signal.

6. If the above steps don’t work, try connecting via mobile hotspot.

Depending on whether you're an iOS or an Android user, you can enable your hotspot by following these steps: 

iOS device: 

  • Open your device's Settings. 
  • From Settings select Cellular and then use the slider to turn Personal Hotspot to on. 
  • Underneath the slider is the password to your hotspot.  

Android device: 

  • Open your device's Settings. 
  • Select Network & Internet. Then Hotspot & Tethering. 
  • Tap Wi-Fi hotspot. Turn this to on. 
  • You may need to set up certain settings such as the hotspot name or password if it has not been enabled previously. To do this, select Set up Wi-Fi hotspot.

Once your Personal Hotspot is enabled, your phone's hotspot can be discovered on the ecobee itself. On the thermostat, open up the Main Menu and then tap Settings >> Wi-Fi >> Network and scroll until you see the device's hotspot name under the available networks.  

NOTE: If you’re able to connect to a hotspot but not to your home network, this indicates an issue with the network. Ensure that you’re connected to a 2.4GHz network, are entering the correct network password and the security settings for your network aren’t too high for the ecobee to access.

If your ecobee is connected to your home network but is unable to connect to ecobee servers, the issue may be caused by security settings on your router. To check if your ecobee is connected to ecobee servers, go to MAIN MENU > ABOUT > WI-FI > CONNECTED TO ECOBEE.COM.

If it's not showing as connected to, follow the steps below:

1. Try power-cycling the ecobee by removing it from the wall and leaving it off for two minutes

2. After two minutes, place the ecobee back on the wall

3. To reconnect to Wi-Fi, go to MAIN MENU > SETTINGS > WI-FI > NETWORK > SELECT WI-FI NETWORK. Choose your home network from the list and wait for the ecobee to reconnect

4. If your ecobee does not connect to Wi-Fi after following the steps above, try connecting to a mobile hotspot.

If you’re able to connect to ecobee server through a hotspot but not through your Wi-Fi network, this may be due to a security setting on your router such as a firewall preventing outbound traffic to Try checking your router and modem configuration. This will involve accessing your router's settings interface, so we would recommend checking online with your router manufacturer (or your ISP if they supplied your router) for advice on how to ensure that no outgoing ports are blocked. Your router and/or firewall settings should permit connections to and * for all ports.
