Whenever Ecobee temperature wrong error messages appear, chances are it’s most likely due to a software issue.
If your Ecobee is reading the wrong temperature, it will incorrectly control your home’s heating and cooling systems.
Even if you face this problem, don’t worry; we have you covered.
The fixes for this seemingly complex issue are incredibly straightforward and quick to perform.
To fix your Ecobee thermostat having the wrong temperature, first replace your sensor batteries. Then recalibrate your thermostat and its sensor units and check their placement. Lastly, perform a factory reset.
Now that you are aware of the solutions we will perform to fix your thermostat temperature, let’s first examine the most frequent causes for this issue:
Why Is My Ecobee Temperature Wrong?
Your Ecobee device can read the wrong temperature due to two issues. The first is a hardware issue with the thermostat device, and the second is a software malfunction.
Here are the most common reasons why your Ecobee thermostat has the wrong temperature:
If the temperature sensor in your thermostat setup malfunctions, this can cause a wrong temperature reading.
If your thermostat has encountered a software error, this can alter the temperature displayed.
When your sensors have a low battery charge, they might send incorrect temperature data.
If your thermostat sensors are placed incorrectly, they might give higher or lower temperature readings than usual.
When your thermostat is improperly wired or has an electrical issue, it can cause it to keep the wrong temperature.
If your Ecobee thermostat is not receiving constant and stable power, it can cause gaps in its temperature reading.
Note: You can download your entire Ecobee runtime report from its web portal and check if there are gaps in the reading, indicating power loss.
How To Fix Ecobee Wrong Temperature?
To fix your Ecobee thermostat from giving the wrong temperature, you must first check for various causes.
Please follow our solutions below in the given order and without skipping to ensure the best results:
Solution #1 Replace Sensor Batteries
One of the causes for your Ecobee reading the wrong temperature is that its sensors have depleted batteries.
This can cause erroneous temperature data to be sent to your thermostat.
Here are the steps to replace your Ecobee thermostat sensor batteries:
- Turn off your Ecobee thermostat
- Open the sensors battery panel located on its backside
- Take out the old batteries and insert new ones
- Restart your thermostat and check if the sensors are reading the correct temperature
Note: Ensure your battery is facing the correct way to make proper contact. If the backside panel is not fully closed, this can prevent your battery from delivering power.
Solution #2 Disable Main Thermostat Sensor
Ecobee thermostat temperature wrong is sometimes caused due to your primary Ecobee smart device reading the wrong temperature.
There is a clever workaround for this issue. It involves disabling the thermostat’s built-in sensor and switching to your auxiliary sensor units.
Here is how to disable the primary thermostat sensor:
- Open the Main Menu from your thermostat display
- Find and select the Sensors tab from the menu
- Unpair the primary sensor by selecting it and taping the remove icon
- Follow the prompts on your screen to remove the sensor from participating
If the sensor is not showing up from the thermostat device, you can also try unpairing it from the Ecobee Web Portal.
Note: If you want to remove the Ecobee thermostat as a sensor, you need at least one other working auxiliary sensor unit.
Solution #3 Check Your Sensor Positioning
If your sensors are placed incorrectly, they can give false temperature readings.
Even though the sensors could give the right temperature, their positioning might cause a faulty temperature measurement.
Here is a list of general causes for an inaccurate temperature reading:
- The sensors are exposed to direct sunlight, causing an artificially higher temperature
- The sensors are close to a device that is emitting intense heat
- Your sensors are placed too low to the ground, causing them to read a cooler-than-average temperature, as cold air is heavier and falls to the ground
- Your thermostat sensor units are placed too far away from the primary Ecobee device and have a weak signal
Note: Try positioning your sensors in an elevated spot that is not close to other heat-emitting sources.
Solution #4 Recalibrate The Sensor
Ecobee thermostat not reading correct temperature can be fixed by recalibrating its sensors.
These solutions must be done for every sensor unit that gives you the incorrect temperature reading.
Here are the proper steps to recalibrate your Ecobee smart sensors:
- Remove the battery panel on your sensor
- Take the battery off and place it with the (+) side facing downward
- Wait for two minutes for your sensor to fully power down
- Restart your Ecobee thermostat by removing it from the wall and powering it off
- If you are using the Ecobee app on your smartphone, restart it as well
- After two more minutes have passed, put the thermostat on the wall again and power it on
After these steps, please wait for your thermostat to complete the restart process.
When you perform the sequence above, your thermostat will recalibrate its temperature sensors automatically upon restart.
Lastly, check to see if all the sensors are properly connected and if the temperature reading is now correct.
Note: If you have your Ecobee thermostat as the only sensor, skip steps 1-3 to recalibrate it.
Solution #5 Hard Reset Your Ecobee Thermostat
If your thermostat has encountered a software error that causes incorrect temperature readings, resetting it to the factory settings will force it to recalibrate.
This method will revert your device to how it was configured before you first installed it.
Here are the steps to hard reset your Ecobee thermostat:
- Ensure your thermostat is powered on during this whole procedure
- Open the Home screen on your device and select the Menu
- Find and tap on the Settings option
- Locate and tap on the Reset panel
- Select the Reset All Settings option and then tap on Yes
- Wait for the procedure to finish
After the procedure, you will be prompted to set up and configure your thermostat again.
Follow the same steps and settings you used before factory resetting it.
Note: A factory reset will remove any saved networks and erase sensor data reports. Ensure you have this data backed up beforehand.
To fix your Ecobee thermostat’s wrong temperature error, first, replace your sensor’s batteries. Then recalibrate your thermostat sensors and check if they are set up correctly. Lastly, perform a factory reset.
Now that you know why the Ecobee temperature wrong error occurs, we hope our suggested solutions can help you fix it.
