Why is Total Connect 2.0 Showing a Wrong Outside Temperature?

Total Connect 2.0 is showing a wrong outside temperature because the location on your account is set incorrectly, or you have your non-preferred temperature unit set to be displayed. You can access your account to fix the location and to set the temperature unit to your desired setting.


If you see the temperature listed in Total Connect 2.0, then that information is obtained from the ZIP Code set on the account. The ZIP Code set as your Total Connect 2.0 location is also used by your Honeywell Alarm Panel to display the local temperature if your panel supports that feature. If you have the incorrect ZIP Code set, then you will likely find that the displayed temperature is incorrect, both in Total Connect 2.0 and on your alarm panel. Additionally, some users may be confused due to their non-preferred temperature unit (Fahrenheit or Celsius) being set for their desired display. Both the location ZIP Code setting and the temperature unit setting can be changed within Total Connect 2.0. Please note that your panel will need to sync with TC2 before its displayed temperature will update.

For this FAQ, we will be showing the steps related to the Total Connect 2.0 website. You can also complete this process using the Total Connect 2.0 Mobile App, but please be aware that the menu options may be in different locations that what is described in this FAQ. Complete the following steps to change your location ZIP Code setting and your temperature unit setting in Total Connect 2.0 so that the correct temperature is displayed.

1. Access TC2 Website. Go to the Total Connect 2.0 website using the latest version of a supported web browser. Supported web browsers include Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge.

2. Log in to your account. Enter your username and password, and click Sign In. Alarm Grid customers have a default username of the email address that they have on file. If you are having trouble signing in, click "Problems Signing In?", or contact your monitoring company for further assistance.

3. Enter Locations Menu. On the left-hand side of the screen, click Locations. You will enter the Locations Menu.

4. Change the ZIP Code. Find the field for ZIP Code, and verify that it is correct. If it isn't delete the existing entry, and enter the correct ZIP Code. Click the blue Save button in the bottom-right corner to save the change.

5. Change the Temperature Unit. At the bottom of the same screen, you will see the Temperature Unit setting. You can set it to Fahrenheit (F) or Celsius (C). Make sure the circle next to the desired setting is filled-in blue. Click the blue Save button in the bottom-right corner to save the change.

6. Confirm updated temperature. The temperature displayed in Total Connect 2.0 should update as soon as you save the changes. But the temperature displayed on your panel (if supported) will not be updated until the system syncs with Total Connect 2.0. You can speed up the process by pressing the blue Sync Panel on the current screen. It may take a few minutes for the Panel Sync to go through.

Hi Ellen. What are the model numbers of your two thermostats?
We have two Honeywell thermostats in the house. They are both set to the same ZIP Code, obviously. Yet, they state two different outside temperatures.
It's hard to say what might be off without having access to the AlarmNet account. You should contact your AlarmNet provider (CMS or whoever it's setup under) to see if they can troubleshoot for you.
Thanks for the response! Mine is a Lynx Touch 7000 monitored direct through a Criticom (CMS) account. Location is accurate in TC 2.0 online but usually just shows 70* despite it being +-. Any tips?
What system do you have and is it monitored?
My location is correct, any idea why the temp is still wrong? My street address is new (new private drive), so perhaps it is not recognized? I'd hope it would be smart enough to use the zip though..

Thanks for the great mini-tutorial! Just changed mine to show the right location and temperature. The installer only gave me the "this is how you arm, this is how you disarm" lesson and was gone. Have to figure the rest out on my own.
