Frequently Asked Questions
Will the T5 Smart 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 Honeywell Home app and will not function while the connection is down. The thermostat will automatically reconnect to Wi-
Fi once the network is restored.
The T5 Smart Thermostat is not finding the in home Wi-Fi network.
The thermostat operates in the 2.4GHz range. That may be why the 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 Home app but it has not shown up on the T5 Smart Thermostat.
There may be a short delay after making temperature and setting changes in the Honeywell Home 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.
How are multiple users set up with thermostat?
Access can be given to any or all thermostat locations through the Honeywell Home 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 an 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 Honeywell Home 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.
There is an alert that says Wi-Fi Signal Lost. What does that mean?
The Wi-Fi signal to the thermostat has been lost. Wait for the thermostat to reconnect or select a new network within the Honeywell
Home 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 thermostat displays a strike-through Wi-Fi icon on its screen or shows up as offline on the Honeywell Home 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.

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
