Mysa Baseboard 3: Temperature offset

Last updated: October 5, 2026

Mysa Baseboard 3 includes a temperature offset in the Mysa app. Use it when the temperature on the thermostat does not match a reliable room thermometer, so heating follows the corrected reading.

How it works

The offset shifts the temperature the thermostat uses up or down by the amount you choose. Example: if the thermostat reads 21°C and a thermometer in the same room reads 22°C, a +1°C offset aligns them.

Default is no offset. Change it only if you see a consistent difference, not a one-time draft or sun patch.

When to use it

  • The thermostat is near a heat source, sunny window, or appliance.

  • The thermostat is on a drafty or exterior wall.

  • You compared it with a separate thermometer and the difference stays the same.

How to set it

  1. Open the Mysa app and select your Baseboard 3.

  2. Open Settings.

  3. Find Temperature offset.

  4. Choose the offset that matches the difference you measured.

Give the room time to settle after you change it before you judge the result.

Related settings on this product

  • Smart Early On (not the older 30-minute Early On) can start heat before a scheduled setpoint.

  • Setpoint limits, heater type, and °C/°F are also in Settings.

  • Baseboard 3 does not include freeze protection.

If you do not see Temperature offset, update the Mysa app and confirm you selected a Baseboard 3 (model BB-V3-0).
