You might need to Change Honeywell Thermostat WiFi. Why? Perhaps you moved it, and the WiFi it worked with before is now out of range. So in this post, we cover how to reconnect a typical Honeywell smart thermostat to a WiFi network. We offer how-to, step-by-step instructions to get your thermostat working fully again.
Perhaps you have changed the name of your home WiFi network. Or perhaps you changed your WiFi network router and didn’t set your new router’s network name and password exactly the same as were the ones on the old router set. Or, you may want to connect the t-stat to a new access point in your home. For all of these cases, you can reconnect a Honeywell thermostat to WiFi by following the how-to directions below.
Change Honeywell Thermostat WiFi: Step by Step
For sure, Honeywell really improved the WiFi setup routine for this smart t-stat. Indeed, you no longer must reconnect to it via a tablet or phone to update the WiFi network settings. Instead, you can now set up the entire WiFi link via the touchscreen menu system on many models. Here’s how.
1. Enter WiFi Setup mode
First of all, switch from normal to WiFi setup as follows. Press the Menu button at the top right of the Home screen, as shown above.
Then, scroll with the arrow keys at right, through the main menu. Stop scrolling when you see the WiFi Setup button, as shown next.
Next, press the WiFi Setup button, circled in red in the above pic. The WiFi setup screen then displays, as shown next. Note that we have blanked the t-stat MAC address and CRC values, to preserve its anonymity. Also note that normally, this screen shows the status of the connected WiFi network. But here, the OurHouse1 network is not in range (no signal). So we’re going to discard the OurHouse1 info, and replace it with an in-range WiFi network in the following steps.
2. Disconnect the T-stat from its Current WiFi Network
Then press the Disconnect from Network button. The WiFi Network Disconnect Confirmation screen appears, as follows.
Press the green Yes button.
After a pause, the system lets you know that it disconnected from the old WiFi network, as shown next.
Then, press the green OK button in the lower right corner of the screen. This takes you back to the main menu, as shown next.
3. Find the WiFi Setup Button
From there then, use the UP and DOWN arrow keys to scroll through the menu to the Wi-Fi Setup button.
4. Tap the WiFi Setup Button
Then, press the red-circled WiFi Setup button. When no network information resides in the t-stat, pressing Wi-Fi Setup starts a scan for in-range WiFi networks.
Then, a brief message displays, telling that the network scan is in progress.
Then, most Honeywell smart thermostats list the in-range WiFi networks they find, on their Select Wi-Fi Network screen, as follows:
5. Find your Desired WiFi Network
Then, tap the network in the list to which you wish to connect the smart t-stat. So in our case, we’re connecting to the 937T681J4059H_2G wireless network. The WiFi Password Entry screen then appears, as follows.
6. Change Honeywell Thermostat WiFi: Enter WiFi Password if Asked For
Next, use the displayed virtual keyboard to enter your password. Then, to enter numbers and punctuation characters, press the ?123 key. Why? Because this switches the keyboard to number entry mode.
The password characters appear as you type them. So do this when no one is looking.
7. Connect to the WiFi Network you Picked
Once you enter the password characters, press the green Done button.
The WiFi t-stat then tries to connect to the chosen WiFi network. While reconnecting, it displays the following screen.
Then, if no errors happen, the system reconnects to the WiFi network you picked.
Then it displays the following screen. It shows the name of the wireless network that the t-stat now connects with.
8. Register the Thermostat Online for Remote Access If You Haven’t Already
Next, press the green OK button.
Then, the Register Online for Remote Access screen displays, as shown next.
Now perhaps you already registered your t-stat. If so, then you need not register it again, so long as you have not unregistered it. Note that reconnecting to a new WiFi network does not unregister a Honeywell thermostat.
Then, press the green Done button.
The system then returns to the Wi-Fi Setup screen. But this time, the connected network settings appear, as shown in the next shot.
Next, press the green Done button.
Then, the t-stat takes you back to the main menu, as shown below.
Then from there, press the Home button at the top left corner of the Main Menu screen, to return to the Home screen, as shown next.
9. Done with Change Honeywell Thermostat WiFi
Finally, your Honeywell smart thermostat now links to your new WiFi network. You’ll see that when the outdoor temperature and humidity settings update soon thereafter. So, you’ve successfully reconnected your Honeywell wireless thermostat to your new or updated WiFi network.
