It seemed kind of cold in my room so i put an Ecoplus therm/hygro in the room and put the remote sensor right next to the CHHC-1 sensor and most of the time they are within a few degrees of each other but I've noticed at times they differ a lot (like 6 or 7 degrees difference.) Has anyone else tried comparing readings from other therm/hygro devices to the CHHC-1? I attached pictures from two different times when they varied a lot.
