So many people love having a Honeywell Thermostat in their home, given that they are convenient and easy to use!
Many of these thermostats have a built-in Wi-Fi feature, which makes them so much more convenient for a homeowner.
However, many homeowners find it challenging to connect these Wi-Fi thermostats, as this process will often not work out the way you want it to.
Connecting your Honeywell Thermostat to your Wi-Fi will differ depending on what model of Honeywell Thermostat you have.
So, you will need to follow different steps than a homeowner with a different Honeywell Thermostat if you want to successfully install one into your home, and keep it connected to your network.
If you are currently experiencing any Wi-Fi connectivity issues, then you won’t need to contact the HVAC professionals just yet!
In this article, we will discuss how to fix the connectivity issues for various
Honeywell Thermostats, so you can get reconnected to the network in no time!
What Is A Honeywell Thermostat?
A Honeywell Thermostat is an electronic device considered to be a smart thermostat.
It allows you to control your heating or cooling system remotely from anywhere in the world.
It’s also known as a programmable thermostat because it has a user interface where you can set temperature settings for specific rooms within your house.
Why Is My Honeywell Thermostat Not Connecting To The Wi-Fi Network?
Your Honeywell Thermostat may not be connecting to the Wi-Fi network for a variety of reasons.
Let’s take a look at a few examples!
The first thing that could cause your Honeywell Thermostats to not connect to the Wi-Fi network is an outdated or missing password.
If you’ve forgotten your password, you’ll need to reset it.
Another reason why your Honeywell Thermostatic might not be able to connect to the Wi-Fi network could be because the device has been turned off by mistake
A third reason why your Honeywell Thermostatic might not be able to connect to the Wi-Fi network is that the WiFi network itself is having issues.
If you have tried everything but still cannot connect your Honeywell Thermostat to the Wi-Fi network, then there are steps you can take to get everything in working order again.
The First Step: Troubleshooting The Wi-Fi Connections.
This is a universal solution for all Honeywell Thermostats. It should be the first one you should try before moving on to other methods.
When it comes to troubleshooting an issue, it is best to begin with the simplest solution and if that does not work, begin searching for more complicated issues.
So, if you are unable to find your thermostat on the Wi-Fi network, you should try the following steps:
Check The Power
The first thing you should do is check the power of the smart thermostat.
Every single Honeywell Thermostat model (with Wi-Fi) has a feature that requires power supplied with the common wire (also known as the C wire.)
If there is no power in your thermostat, then you are experiencing a wiring issue, and it is best to call the HVAC professional to fix it.
Check The Wi-Fi Frequency
Next, you need to check the Wi-Fi frequency.
These Wi-Fi thermostats will only work on a 2.4GHz frequency (wireless), which the majority of Wi-Fi routers will be able to transmit.
For this step, you will need to check your router and configure it to transmit via this frequency. This should fix the Wi-Fi connectivity issues of the thermostat.
Check The Wireless Range
There is a limit in range when it comes to wireless signals, and they’re easily affected by barriers that will cause the signal to weaken.
These barriers can be physical or come from electromagnetic interference.
So, your Honeywell Thermostat can lose signal intermittently if it is at the edge of the range of the signal, or if there is any interface nearby.
To fix this issue, you should try and move the router so that it is close to the thermostat. Alternatively, you can try installing a Wi-Fi booster close to the thermostat.
Check The Router Firewall
Sometimes, the issue can lie with the firewall of the router.
In this instance, it is best to check that a connection between the thermostat and the Wi-Fi is being permitted by the firewall.
Try Switching It Off And On Again
We know this is a cliché saying, but it does sometimes fix the issue! You can attempt to restart the Wi-Fi router by switching it off and on again.
This may solve any issues the router is having with the Wi-Fi network, or any broadcasting signals it may have.
If your Honeywell Thermostat still won’t connect to the Wi-Fi even after trying these steps, then you will need to try something more specific to the thermostat you have at home.
Connecting Your Honeywell Thermostat To The Wi-Fi Network
Let’s check out the different Honeywell Thermostat models and how they can be connected to our respective Wi-Fi networks!
The 6000 And 8000 Series Thermostats
If you have a 6000 series thermostat, the first thing you need to do is check whether it can connect to the Wi-Fi or not.
Often, many 6000 series models will not be able to, and you can check yours by finding out the specific model number.
If your Honeywell Thermostat can connect to the Wi-Fi, then you will see a WF designation written next to its model number.
The 6000 series thermostats that have Wi-Fi capabilities are:
The 8000 series thermostats that have Wi-Fi capabilities are:

Frequently Asked Questions
How Do I Know If My Thermostat Is Connected?
Look at the bottom of your thermostat. If there are two small dots, then it means that it is connected.
If there is only one dot, then it means that the thermostat has not yet been connected.
Why Does The Thermostat Say “Not Connected”?
It means that the thermostat’s Wi-Fi is currently disconnected from the internet. The reason why it says this is that you haven’t configured the thermostat to be able to communicate with the internet.
What Should I Do If My Thermostat Says “Connecting…”?
This usually happens when the thermostat is trying to establish a connection to the internet.
Please wait until it finishes connecting to the internet before continuing any further.
How Can I Find My Thermostat Model Number?
You can find out by looking at the back of your thermostat (the model number).
It will say something like HX7000 or HX8500. This is how you know what type of thermostat you have.
Are All Honeywell Thermostats Interchangeable?
Yes, all Honeywell thermostats are interchangeable., but only the “T” series of thermostats.
They use the same technology, but they have different features. For example, some models have an extra feature called “Smart Schedule”, while others don’t.
Can I Use An Old Version Of The App With Newer Thermostats?
Yes, you can use an older version of the app if you want to. However, newer versions of the app are better equipped to handle new devices.
So, if you’re using an old version of the app, then you might experience issues.
How Long Will It Take To Reconnect My Thermostat To The Internet?
The time depends on the speed of your internet service provider.
We recommend that you try to reconnect your thermostat within 10 minutes after disconnecting it from the internet.
Is There Any Way To Check Whether My Honeywell Thermostat Has Been Successfully Configured?
You’ll see whether the thermostat has successfully been configured in the “Device Settings” section of the app.
If it hasn’t, then you can manually configure it.
It can feel a little stressful when you have a Honeywell Thermostat (see also our Honeywell thermostat troubleshooting tips) that will not connect to Wi-Fi.
Until it does, you will not be able to control the thermostat from your smart device.
There are many reasons why your thermostat has lost connection to the Wi-Fi network, but luckily, the ways of fixing it are all very easy.
The first step you should take for all models of your Honeywell Thermostat (see also ‘How To Clear Schedule On Honeywell Thermostat: Series 2000 – 9000 Models‘) is to troubleshoot it and see if this fixes the issue.
If it does not, then you need to follow different step-by-step methods, depending on your thermostat, to reconnect it to your Wi-Fi network.
Luckily, these steps are easy to follow, and you should have a connected thermostat and Wi-Fi network in no time!
If you do not, then the problem lies elsewhere, and you may need to seek outside help to connect the Thermostat to the Wi-Fi network.
