Honeywell Lyric T5 Wi-Fi Thermostat Installation Guide

Frequently Asked Questions  
Will the Lyric T5 Wi-Fi thermostat still work if Wi-Fi connection is lost?  
Yes, the temperature can be adjusted directly at the thermostat. However, some features,  
including geofencing, are managed only through the Lyric app and will not function while the  
connection is down. The Lyric thermostat will automatically reconnect to Wi-Fi once the network  
is restored.  
The Lyric T5 Wi-Fi thermostat is not finding the in home Wi-Fi network.  
Lyric thermostat operates in the 2.4GHz range. That may be why the Lyric thermostat does not  
see the network but the smartphone, which operates in both the 2.4 and 5.0 GHz range, sees the  
network. Most routers will broadcast two networks, one SSID on the 5.0 GHz radio and one SSID  
on the 2.4 GHz radio.  
A change was made on the Honeywell Lyric App but it has not shown up on the Lyric T5 Wi-Fi  
thermostat.  
There may be a short delay after making temperature and setting changes in the 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 Lyric 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.  
How are multiple users set up with Lyric thermostat?  
Access can be given to any or all Lyric thermostat locations through the Honeywell Lyric App.  
Start by touching the three-line menu icon in the upper left-hand corner of the home screen.  
Select Manage Users and touch Add User located at the bottom of the screen. Type in the  
email address of the person to be invited. If they have a Lyric account set up, the location will be  
automatically added to their account. If they don’t have an account, they will receive an email  
invitation prompting them to download the app and create their own account.  
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 Wi-Fi signal is determined by the router. Check the router’s manual  
for additional information.

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.
