Partially embedded cabinets on the exterior wall - mold?

the sensor is now behind the back panel of the cabinet, which borders an interior wall. But I don't think the measured values will be dramatically different 30 cm further to the left towards the exterior wall, right?

I just measured with an IR thermometer at my place. 0.5 degree difference between exterior wall and interior wall. So almost the same temperatures (it’s also a house optimized for new construction with corresponding insulation).

Okay, thank you for your efforts. Then I will do nothing for the time being. I assume that I can apply the same considerations to the built-in furniture that is placed entirely against interior walls.
