WiFi Setup and Troubleshooting

Video: Wi-Fi Network Connection and Resideo Pro App Setup

Watch this video for step-by-step instructions on connecting your ElitePRO™ Series Thermostat to the Wi-Fi network and Resideo Pro App.

During the initial installation, after the Installer setup, the thermostat will prompt you to set up WiFi and guide you through the steps. If you are setting up WiFi after the initial installation has already been done, follow the steps below:

  1. On the thermostat, touch the Main Menu icon in the lower-left corner of the display.

  2. Then select WiFi.

  3. There is a slider labeled “Enable WiFi”. Make sure this is set to the right.

  4. Touch Choose Network.

  5. After a brief delay, the thermostat should show the available networks. Choose your home network from the list.

  6. If this is a secure network, it should prompt you to “Enter WiFi password”. After a brief delay the display should show “Success! Your thermostat successfully connected to the network.” Touch the OK button. NOTE: If you did not successfully connect to the network:

  7. The homeowner should Download the First Alert App from the App store or Google Play. If the installer did the setup with Resideo Pro app and sent them an invite with the email they use for this account, that thermostat will show in their app. If not, they will need to choose to add a device and follow on-screen steps.

Connect to a Hidden WiFi Network

  1. Touch MENU, then WiFi Setup.

  2. Touch Other.

  3. Enter the network name.

  4. Select the appropriate network security setting, then touch Select.

  5. Enter the WiFi network password.

Unsuccessful WiFi Connection

If you are unsuccessful in connecting the thermostat to the WiFi network, you will see a Connection Failed screen. Here are three specific reasons the connection might be unsuccessful.

Invalid Password

The password you entered is invalid. Check that you have the right password and try again.

No IP Address

The thermostat was unable to obtain an IP address from the router. Verify the router is correctly set up to automatically assign IP addresses. This connection can take several minutes. If there is still no connection, remove the thermostat from the wall plate for 10 seconds, then snap it back into place.

No Internet Link

The thermostat connected to the WiFi network but was unable to establish a connection to the internet. Check the router settings and try again. Make sure the Ethernet cable is plugged into the router and try rebooting the router if necessary.

WiFi and App FAQs & Troubleshooting:

Q: Will the thermostat still work if the WiFi connection is lost?

A: Yes, you can still manually adjust the temperature at the thermostat. However, some features such as location-based temperature control (Auto-Away using geofencing technology) can only be managed through the First Alert App and will not function without a WiFi connection. The thermostat will automatically reconnect to WiFi once the network is restored.

Q: Is there a way to extend the strength of my WiFi signal?

A: The range (distance) of your WiFi signal is determined by your router. Try moving your router closer to the location of the thermostat, or use a router with a stronger signal range.

Q: There’s an alert that says “WiFi signal lost” - what should I do?

A: Cycle power to the thermostat. This can be done with the switch on the side of the furnace, at the furnace breaker or by removing the thermostat from wall plate and then reattaching after 10 seconds or more. Wait 5 minutes for the thermostat to reconnect or select an alternate network (if you have one) in the First Alert App configuration menu. If the thermostat isn’t able to reconnect, you’ll need to troubleshoot the router to determine the cause.

Q: The thermostat or app is showing "Datasync". What should I do?

A: Remove the thermostat from wall plate, wait 30 seconds, then reattach it. If the issue persists, unregister and re-register the thermostat by deleting the thermostat from the app, then tap Add new device to reconnect it. In the unlikely event that this doesn't resolve the issue, connect the thermostat to a hotspot or alternate network for 24 hours, then perform a WiFi reset and reconnect it to your home network.

First Alert account and app questions

Q: Why haven’t I received an account activation email?

A: If you haven’t received an activation email within 5 minutes, check your Spam folder for a message from customer-service@resideo.com. If you don’t see it, tap Resend to have the activation email sent again. If you still don’t receive it, please contact the Technical Support team at 1-800-633-3991.

Q: Can I set up my thermostat with multiple users?

A: Yes. To add users, log into the First Alert App and tap the menu icon in the upper left corner. Select Users, tap Invite Users and type in the email addresses of the people you’d like to invite. If they already have a First Alert account set up, the thermostat and its location will automatically be added to their account. If they don’t have an account, they’ll receive an email prompting them to download the First Alert App and create a new account.

Q: Can I set up location-based temperature control with multiple users?

A: Yes. Location-based temperature control (Auto-Away / geofence technology) will activate based on the last person who leaves and the first person to return. Each user will need to create their own First Alert account with a login ID and password. Two users should not share the same account. Each user will then need to enable location-based temperature control.

Q: Why doesn’t a change I made in the app show up on the thermostat?

A: There may be a short delay when you make temperature and settings changes in the First Alert App. Wait a few minutes, and if you still don’t see your changes on the thermostat, make sure the thermostat is still connected to WiFi and restart your First Alert App.
