Interior side of exterior windows in my apartment gets occasionally very foggy, especially during mornings. Too high air pressure indoors can cause this, but one time measurement by the constructor showed the air pressure to be fine, so lower indoors than outdoors. The constructor thought that drying concrete might cause the issue. I want to debug the cause of the fog in more detail. The fog appears at particular times of the day, so I thought to follow the air pressure and humidity in detail in time at three locations: indoors, between the windows, and outdoors.
Have you tried a similar application or do you have tips on how to execute? I already got a tip to calibrate first the Ruuvis so you know if there is a constant drift between their measurements. Should I just tape the outdoor Ruuvi to the outdoor wall? Does snow interfere with measurements?
