Frequently Asked Questions  
There is an alert that says Wi-Fi Signal Lost. What does that mean?  
The Wi-Fi signal to the Lyric thermostat has been lost. Wait for the thermostat to reconnect or  
select a new network within the Honeywell Lyric 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 Wi-Fi icon) on top of right corner  
of thermostat display?  
If the Lyric thermostat displays a strike-through Wi-Fi icon on its screen or shows up as offline on  
the Honeywell Lyric App, it has lost connection to the network. Make sure the router is powered  
and broadcasting. The home’s Wi-Fi 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 email will be sent from connected-Home@alarmnet.com. An activation email is needed to  
complete the Lyric 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 Lyric Technical Support  
team at 1-800-633-3991 for help.
