How To Fix Amazon Thermostat Not Connecting To Wifi?

Similar to many other smart home gadgets, the Amazon thermostat may encounter occasional issues, and one of the most commonly reported problems by users is connectivity failure.

A reliable Internet connection and stable Wi-Fi are essential for your Amazon Thermostat to seamlessly link up with the Alexa app, enabling you to remotely manage your HVAC system, receive notifications, and access its full range of smart features.

Many factors can cause connectivity issues with your Amazon thermostat, including outdated firmware, weak Wi-Fi signals, radio frequency interference, or a problem with your router.

Here’s an article that shows you how this device will behave when it’s not connected to the internet: “Can Amazon Thermostat Work Without Wifi?”

How Do I Troubleshoot Amazon Thermostat Connectivity Issues?

There are plenty of things you can do in order to reconnect your thermostat and get it working again, and I’ll show them to you in the following sections.

So, if you’re ready, let’s dive in and get started.

Tip 1: Restart Your Router.

It is important to restart your router as this process can maintain a healthy and fast internet connection and allow the router to fix internal software errors and crashes.

So when you notice connectivity issues with your Amazon Thermostat go and power cycle your router, and here’s the correct way to do it:

  1. Power down and unplug the router (If your router has a battery backup, you will need to take the battery out).
  2. Allow to sit for 60 seconds unplugged.
  3. Plug in and turn on the router, and allow it to completely boot up until the front panel connection lights on the router show a steady connection.

Tip 2: Check The Firmware.

The firmware is a program that is “embedded” in a hardware device and is an essential part of the Amazon Thermostat, it provides instructions to help the thermostat start up, communicate with other devices, and perform basic input/output tasks.

The manufacturer usually releases updates for this firmware to fix bugs, keep the device running smoothly and avoid all sorts of problems including connectivity issues.

So make sure that your thermostat is running on the latest firmware. Updating your Alexa app is also essential to help fix connectivity issues.

Tip 3: Connect Your Thermostat To The Right Frequency and Reduce Interference.

It is important that your Amazon thermostat is paired to the correct frequency to successfully connect to your network. This device works on the 2.4 GHz only, 802.11 b/g/n. Does not support 5GHz networks or connecting to ad-hoc (or peer-to-peer) wifi networks.

Make sure the 2.4GHz channel is enabled on your router when connecting the thermostat.

Since many smart home devices operate on the same frequency, interference issues may occur.

Radio frequency interference is another cause of connectivity issues, so I recommend moving devices that operate on the same spectrum such as Microwave ovens, Wireless Bluetooth speakers, and smart home devices that work on a 2.4 GHz channel.

Tip 4: Reset Your Amazon Thermostat.

A factory reset is also a good solution to consider when your thermostat isn’t connecting to Wifi, the only downside of this process is that it will erase all data on the thermostat, including HVAC configuration and device settings.

Here are the instructions to follow in order to reset your Amazon Thermostat:

  1. On the Smart Thermostat, press the Up Temperature, Down Temperature, and Mode buttons together for 10 seconds until rEs appears on the display.
  2. Press and hold the Mode button for 5 seconds, until the device resets.

Tip 5: Improve Wifi Signals.

When Wifi signals don’t reach your thermostat, connection problems appear and this often happens when there’s a long distance between the router and the thermostat.

You can boost your WiFi signals by moving the router to a location where it can broadcast signals throughout your home, or you can install a WiFi range extender to extend the signals.

If you live in a large house, I recommend setting up a mesh network because it is very efficient in terms of spreading Wifi signals.

Tip 6: Make Sure the Wifi is enabled on your mobile.

The Amazon Thermostat is linked to the Alexa app, and it connects and shares data using Wifi communication protocol, so your mobile’s Wifi needs to be enabled to let the Alexa app communicate with the thermostat exchange information and receive commands without any problem.

Tip 7: Reset The router.

A router reset is also an option to fix this issue, from no Internet connectivity to slow wireless connections, and should be one of your troubleshooting tips when your Amazon thermostat won’t connect.

Here are the instructions to follow in order to reset your router:

  1. Make sure the router is On.
  2. Pick a paperclip to hold down the Reset hole at the back of the router for half a minute.
  3. Release the Reset button and wait 30 seconds for the router to fully reset and power back on.

Tip 8: Contact Customer Support

The last thing you can do if all the previous solutions haven’t solved your connectivity issues is contact customer support and they’ll tell you what to do, the Amazon Thermostat has a 1-year limited warranty and service included, so they can fix it for you.

Final Thoughts.

So these were the solutions that you can implement when your Amazon Smart Thermostat won’t connect to Wifi, you can take this article as a guide each time you face this issue.
