Frequently Asked Questions  
Will the X2S Smart thermostat still work if WiFi connection is lost?  
Yes, the temperature can be adjusted directly at the thermostat. However, some features, including  
geofencing, are managed only through the First Alert app and will not function while the connection is  
down. The thermostat will automatically reconnect to WiFi once the network is restored.  
A change was made on the First Alert app but it has not shown up on the X2S Smart thermostat.  
There may be a short delay after making temperature and setting changes in the First Alert app.  
Can there be multiple users for geofencing?  
Yes, there can be multiple users. Geofencing will trigger based on the last person to leave and the first  
person to return. To properly use geofencing with multiple users:  
•
•
Each user needs to create their own account.  
Each user should use their login ID and password across his or her devices, including  
smartphones and tablets.  
No two users should share the same account.  
•
Can more than one user control the thermostat with the app?  
Yes. Use the First Alert app to invite other users to download the app and share control of your  
thermostats. In the app, go to the hamburger menu and select “My Locations”. Select the location you  
want to add users to and select “invite user”.  
Note: All individuals with access to a thermostat share the same user privileges. Users added will be able  
to change the thermostat’s settings, as well as add or delete other users.  
Is there a way to extend the signal strength?  
The range or distance of the WiFi signal is determined by the router. Check the router’s manual for  
additional information.  
There is an alert that says WiFi Signal Lost. What does that mean?  
The WiFi signal to the thermostat has been lost. Wait for the thermostat to reconnect or select a new  
network within the First Alert app configuration menu. If the thermostat is unable to reconnect, you will  
need to troubleshoot the router to determine the cause.  
Why is the thermostat showing up as offline (strike-through WiFi icon) on lower part of thermostat  
display?  
If the thermostat displays a strike-through WiFi icon on its screen or shows up as offline on the First  
Alert app, it is not connected to WiFi. If your thermostat was previously connected to WiFi and has lost  
connection, make sure the router is powered and broadcasting. The home’s WiFi network may need to be  
reset by power cycling the router. Consult the router’s instruction manual for directions on power cycling.  
When the network has been restored, the thermostat will automatically reconnect.  
An activation email hasn’t been received.  
An activation email will be sent. An activation email is needed to complete the account setup. If an  
activation email is not received after five minutes, check the Spam folder of the email account.  
If you do not find it in the Spam folder, click on the Resend button and the activation email will be resent. If  
you still do not receive your activation email, please contact the Technical Support team at  
1-800-633-3991 for help.
