Honeywell Wi-Fi Thermostat Connection Problems and Troubleshooting Tips
If you’re on this page, my guess is you’re having difficulties connecting your Honeywell Thermostat to Wi-Fi, or the designated app. If that guess was correct, then this post is your go-to resource.
In the next few paragraphs, we look at how to troubleshoot common connection issues with your Honeywell Thermostat. Let’s begin!
How to Fix Honeywell Wi-Fi Thermostat Connection Problems
1. Check That Your Internet is Stable and Working Correctly
Sometimes, connection problems are caused by your Wi-Fi network/internet service and not the thermostat. So before you try any other troubleshooting steps, first confirm that your router is working fine. Check to see if the device is offline or not sending a suitable speed to allow your thermostat to connect.
A simple way to do this is to try connecting other devices to your home Wi-Fi network. If it works fine, then the problem is not from the router. But if it doesn’t, then you want to troubleshoot the router to fix the issue. You may reset your router if needed and try to bring it closer to your thermostat to improve Wi-Fi signal strength.
Note that weak network signal strength may also cause connection issues. So if your Wi-Fi signal strength is weak, move the router closer to your thermostat or upgrade it to improve signal strength.
2. Ensure You’re Connecting to a 2.4GHz Wi-Fi Band
As you probably know, most Wi-Fi routers today have two network bands; 5 GHz and 2.4 GHz. While you may enjoy a high speed with the 5GHz band, most Honeywell Thermostat models do not support the 5GHz Wi-Fi network band and this may be the reason for connection failure.
So check to see if your router has two Wi-Fi network bands and switch to the 2.4GHz band.
What this means is, your Honeywell Thermostat may not support a 5GHz Wi-Fi network band, so switch to 2.4GHz and then try to connect your thermostat again to see if it works.
Also, ensure you’re connecting to the same Wi-Fi network used on your phone.
3. Ensure You Are Using the Right Honeywell App
Honeywell smart thermostats work with two different apps. So, you want to be sure you are using the right app.
Depending on the model of your thermostat, you will either use the Honeywell Home App or the Total Connect Comfort App.
In detail, the Honeywell Home App only works with Honeywell T-Series and Round Smart Thermostat models, while the Total Connect Comfort App works with VisionPRO, Prestige, Wi-Fi FocusPRO, and Wi-Fi programmable thermostats.
So, check to be sure which app is compatible with your exact thermostat to avoid connection issues.
4. Update Your App
If your app is out of date, chances are you may encounter connection issues. And as you probably know, updates are rolled out to fix bugs that may cause connection issues and the like.
So if you’re currently experiencing connection issues, updating your app is one of the troubleshooting steps to try.
Depending on your smartphone, check for updates on Google Play Store or Apple App Store and update the app if there are new updates.
You may also want to turn on the auto-update to ensure you keep your app updated.
5. Reduce Network Traffic on Your Home Wi-Fi
Interference from other devices in the shared Wi-Fi network can also cause connectivity issues for your thermostat. So try to reduce the number of devices connected to your home Wi-Fi at once—ten devices at a time are okay.
More so, most routers have a limit to how many devices you can connect at a time. So check to see if your router has reached its maximum number of devices. If so, disconnect some devices and then try to connect your thermostat again to see if the connection issue is fixed.
6. Reset Your Thermostat
For the most part, performing a factory reset will help fix many problems you have with your thermostat, including Wi-Fi connection issues.
So if you have tried all the above troubleshooting steps and your thermostat is still not connecting to Wi-Fi or the designated app, then factory resetting it is your best bet.
Resetting a Honeywell thermostat is usually a seamless process. All you need to do is to Power Cycle it for about 30 seconds or press and hold the Reset button for 30 seconds or so.
Note that Honeywell thermostats are of different models. If this reset method doesn’t work for you, check your User Manual for specific instructions on how to reset your thermostat.
More so, keep in mind that factory resetting your thermostat will erase all previous custom settings and then restore default settings. So make sure to set up your device again to ensure continuous reliable operation.
This should fix the connection issues with your Honeywell Thermostat, but if it doesn’t, then you want to have an HVAC expert check it or contact Honeywell for help.

Sometimes, the issue could be that your wireless network is not showing up when your thermostat searches for networks that are in range during the initial setup. To fix this:
- Ensure your router is turned on.
- Check that your SSID is not hidden (most SSIDs are hidden by default)
- If hidden, manually enter your network name and the security protocols it uses (WEP, WPA, TKP, WPAT…).

Final Thoughts
Although Honeywell thermostats are not prone to Wi-Fi connection issues, they sometimes happen. And sometimes, these issues might be caused by incorrect connection procedures, unstable internet, unsupported Wi-Fi network band, and the like.
So if you’re currently experiencing connection issues with your Honeywell Thermostat, be sure you’re following the appropriate connection instructions and ensure your internet connection is working correctly.
Also, check your Wi-Fi network band (and switch to 2.4GHz), update the app, and reset the thermostat if needed to fix any bug causing connection problems.
