Fix Ecobee Keeps Changing Temperature

The Ecobee smart thermostat has been installed and working perfectly for over two years now, but recently it’s started to change the temperature every few minutes on its own.

As it is generally used to maintain the temperature of rooms, offices and many other closed places. And when it accidentally starts changing its temperature which is not normal, it starts causing trouble in the room’s humidity. It should be fixed at the right time.

I’m not sure what caused this or how to fix it, so I was wondering if anyone else had this problem or knows how to fix the issue.

What you need to do is simply follow the instructions mentioned in the article. You will be able to solve the problem by the end of the article if you follow the instructions as it is.

Reset your thermostat

The first thing you want to do when your thermostat keeps changing temperature is turn it off completely and then back on.

This way, it will forget all of its settings, which should help stop it from shifting between two extremes (and keep it from turning on unnecessarily).

To reset your thermostat: hold down the home button for three seconds until you see reset appear on-screen; release; push and hold down again for another three seconds; let go.

Wait a minute or so after doing that before plugging your thermostat back in.

That’s pretty much all there is to it! Hopefully, resetting your thermostat should get things back under control. If not, continue reading.

Reconnect to Wi-Fi

If your Ecobee thermostat keeps changing temperature, you may need to reconnect to Wi-Fi. Before troubleshooting further, make sure that your thermostat is connected to Wi-Fi and that there are no other Wi-Fi connections nearby.

If you got your problem solved by merely reconnecting to the wi-fi, congratulations, you got your problem solved finally! If not, then follow the article.

Restart your Ecobee 

Restarting your Ecobee may fix issues with inconsistent or slow signal strength. You can restart your thermostat by unplugging it from its power source for one minute, then plugging it back in.

If you’re having trouble connecting with Wi-Fi in a particular area of your home, check that your Ecobee is compatible with that type of connection.

Check temperature settings

The first step to fixing a problem with your Ecobee thermostat is checking your settings. How do you know what settings you have in place? Look at your schedule.

On most models, temperature changes take effect when you set them up and when your thermostat switches into Home or Away mode, for example.

If you’re experiencing an issue where your Ecobee keeps changing temperature on its own, there are a few things to check:

Verify that Your Schedule is Correct – Take a look at whether any of your settings are in conflict with one another.

Maybe there’s some downtime that needs to be eliminated or perhaps something has been accidentally disabled in order for another function to work correctly.

Reset your remote sensors

A common cause of keeps changing temperature issues is unplugged or improperly plugged in remote sensors.

If you find that one of your remote sensors has been unplugged or otherwise disconnected, don’t fret—just plug it back in!

If a sensor was improperly placed (more than three feet from your thermostat), then you’ll need to move it closer and/or remove some obstructions.

In most cases, after moving an improperly placed sensor, your app will automatically detect it and update its connection status.

If that doesn’t work, try restarting your thermostat by pressing on its left-hand side for about 10 seconds. Once restarted, sensors should automatically reconnect; if not, reset them again by pressing on their left-hand side for five seconds.

Update the firmware

Even if you’re only using one of your room sensors to control your thermostat. When you shut off that sensor, it may appear to turn off some other sensor in another room as well. To fix a temperature suddenly changing while everything is turned on.

Turn off all room sensors—either by selecting Off or Disable from their menus—and restart your thermostat. Only then should you turn on any of your room sensors.

You may also want to make sure that each sensor is properly connected to its corresponding base unit. There are no obstructions between them.

Turn off Room Sensors

If you have sensors in individual rooms, disable them to stop your thermostat from constantly adjusting for temperature changes. You can also try closing doors in rooms that don’t have occupants.

If your thermostat still isn’t getting enough information, it might just not be calibrated correctly. Try setting your target temperature a few degrees higher or lower than what feels comfortable to see if you can get a steady reading.

For example, setting it to 75°F (24°C) may work better than 72°F (22°C). Once you find a good balance between comfort and monitoring, try going back to your normal settings.
