No, the Mudita Harmony does not have a working thermometer.

Thermometer Not Available

In the early promotional materials for the Mudita Harmony, we mentioned that a thermometer will be included as one of its features.

Although the Harmony does physically include a temperature sensor, we were unfortunately forced to deactivate it due to inaccurate measurements. It appears that the sensor's readings were affected by the clock's other electronics. Unfortunately, even a very small amount of heat that couldn't be felt outside the casing could throw off the measurements enough to make the thermometer feature impractical.

It's unlikely that we'll be able to find a way to properly calibrate the thermometer in the Harmony, so this feature will most probably remain inactive.
