Honeywell Thermostat Not Communicating: How to Fix

The convenience of not having to get up to adjust the temperature makes smart thermostats worthwhile. As a result, Honeywell Thermostats have made life simpler because you can manage them with your phone. However, sometimes the thermostat may have trouble communicating with the app.

It can be troublesome, but you don’t have to call a professional. In most cases, the issue can be resolved quickly. Fortunately, we have a list of such fixes for you to try. We will go through these to identify the problem and save you from unnecessary repair costs.

One of the first things to do if your thermostat isn’t working properly is to power cycle it. You can do this by removing the batteries and putting them back in. If your thermostat doesn’t have batteries, go to your breaker box and find the switch for your thermostat. Then switch it off and back on.

More so, make sure your Wi-Fi is working. If the problem persists, try reinstalling your app.

These few measures can sometimes solve the issue. Other times, you need to explore more troubleshooting tips. Keep reading.

Tips to Troubleshoot a Honeywell Thermostat that Isn’t Communicating

Ensure that You Have the Right App

Honeywell has dedicated apps for its thermostats. You can use these apps to control them. However, it isn’t a one-size-for-all situation. There are two apps; the Honeywell Home App and the Total Connect Comfort App.

The Honeywell Home App, now called the Resideo App, lets you use your phone to control the connected devices. It has many features, but the important thing is that it’s compatible with the T series thermostats. You can find the specific products on the website.

The other app, Total Connect Comfort, is only compatible with two thermostat models. These are the Wi-Fi Color Touchscreen Thermostat and the VisionPRO 8000 Wi-Fi Programmable Thermostat.

The Honeywell Thermostats will not communicate with the device if you don’t use the right app. No amount of reinstalling or tips can fix that. Additionally, you should update the apps to the latest versions. You also need to enable any permissions necessary for the app to function.

Make Sure Your Wi-Fi Is Okay

Even if your Wi-Fi is working, you need to check a few things. To begin, ensure that your device and thermostat are both connected to the same network. Your smartphone is most likely the culprit in such cases, so check that connection. No connection will occur between devices that are on different networks.

If the network is connected but not functioning, check the IP address. Sometimes the thermostat is connected to the network but doesn’t have access to the internet. If that’s the case, your IP address should have a few “x”s or “0”s at the end. You’ll need to get in touch with your internet service provider to resolve this.

Check the bandwidth too. Depending on your thermostat model, you’ll most likely need a 2.4GHz. However, the T9 and T10 models are different. These models need a 5GHz band for connection.

Remove Any Unnecessary Firewalls

If you have any additional firewalls running, now might be the time to remove them. Firewalls usually monitor traffic on your devices, but sometimes they can glitch. They consider the Wi-Fi connection a threat when that happens and block it.

If you keep getting error messages, disable the firewalls. After that, you shouldn’t have any trouble connecting the thermostat.

Clean Your Thermostat

If you still have your thermostat detached, you might want to clean it quickly. It isn’t unusual for thermostats to accumulate dust and grime. Sometimes the dirt can interfere with the function. So, if nothing else works, try to clean the buttons and the rest of the body.

Check the Batteries and Other Connections

When the battery is low, the thermostat will stop connecting with networks. You can tell the battery is low by looking for the sign on the interface. If that’s the case, change the batteries, which should solve your issue.

Furthermore, look at all the wires and connections to see if they’re broken. If you see any broken wiring or anything, call an electrician. Don’t risk your safety trying to fix anything on your own if you don’t know what you’re doing.

Reset Your Thermostat

If none of the above methods work, try resetting your thermostat to its original factory settings. Just press the “menu” button for a while. After clicking reset, choose the factory reset option.

Depending on your thermostat’s model, you might not see the “menu” option. In such cases, press the “preference” option and see the “menu” option. The rest of the process remains the same.

Remember, the thermostat will return to factory defaults. That means your settings will be deleted too. So if you have customized any settings and want to keep them, remember them. You can alter the settings again after the thermostat reconnects.

Get a Professional

Connection problems are pretty common, and the above tips will fix them more often than not. However, if they don’t, your thermostat may have a different problem, and you may need professional help.

Contact Honeywell customer support. Inform them of your thermostat’s model and issue. They’ll try to guide you on call; however, if that doesn’t work, they’ll send a professional to see the problem.

Hire a freelancer if you don’t want to speak with customer support. You’ll do it, though, at your peril. Thus, ensure that the person is legit with the right qualifications so they don’t make things worse.

Final Thoughts

If your thermostat is having trouble connecting with the Wi-Fi, the HVAC system, or your phone, it’ll be hard to regulate the temperature. Most of the time, the issue isn’t very serious. So be sure to follow these tips before you call in a professional.

Professional consultations will cost you some money. If the solution is as easy as the ones above, you’ll regret spending that money. Ensure the Wi-Fi, app, and other things are working fine. If that doesn’t work, it’s time to call the experts.
