The Room Temperature on my Mysa Seems Wrong, Why is That?

Here’s How Mysa Works!

Mysa’s temperature sensors are state-of-the-art and designed to be very accurate. Precision was top of mind when we designed Mysa, which is why it is such an efficient tool to cut down on home energy expenditure.


However, because Mysa is a more advanced device than your traditional thermostat, there are some factors that should be taken into account, as well as a couple of fixes for common issues.


Where is Mysa Installed?

Where Mysa is mounted in relation to the heater is very important. Mysa reads the temperature at its location, not the temperature from the heater. If your Mysa is located directly above the heater, this will cause a discrepancy between the actual ambient temperature in the room and what your Mysa is registering. Temperatures in rooms can vary based on room size, wall materials, and can be affected by inefficiencies in insulation, windows, and other aspects of your home’s construction.


Mysa Calculates Based on More Than Just Ambient Temperature

Mysa also factors in humidity and the electrical current passing through to determine room temperature. This heat generated by the current passing through your Mysa should not affect the temperature reading - however, there are cases where building materials surrounding your Mysa and its placement can affect the reading by a small amount.


Other Considerations

When using an external room temperature sensor to measure the room temperature, don't place it on top of your Mysa. Mysa vents out air through the top of the unit, and this will give an incorrect reading on the temperature sensor. Please note that when measuring the ambient temperature, infrared thermometers are not recommended to be used to compare the ambient temperatures as it only measures the surface temperature.



Rebooting Mysa

A number of issues can be resolved by simply rebooting your Mysa. The steps listed here will solve most issues:

  • For Mysa for Air Conditioners and Mini-Split Heat Pumps, unplug the power cord for your Mysa from its power source, wait around 30 seconds, and plug it back in. 

Warning! High Voltage!!
Any work with high voltage equipment can be dangerous or even fatal if you do not take proper precautions. You should never work with live wires.

  • For Mysa for Baseboard Heaters V1/V2 and Mysa for In-Floor Heating, this can be done by:

    • Flipping the breaker controlling your Mysa OFF, waiting around 30 seconds, and flipping it back ON.


    • Removing the faceplate on your Mysa. Follow the steps below:

      • Unscrew the faceplate - there’s a small screw at the bottom of your Mysa.

      • Carefully slide off the faceplate.

      • Keep it unattached for 5-10 minutes.

      • Carefully reattach the faceplate. Be careful not to bend the pins that connect it to the base of your Mysa!

      • Your Mysa will take a few seconds to reboot.
