Hereby an overview of the differences in the temperature & humidity readings of my THGR328 sensors. All readings recorded at the same time and same physical position.
THGR328 (1): 19,6 degrees C, 45% humidity
THGR328 (2): 19,5 degrees C, 35% humidity
THGR328 (3): 70,0 degrees C, 50% humidity (device broken, DOA)
THGN132N (1): 20,9 degrees C, 44% humidity
THGN132N (2): 20,7 degrees C, 42% humidity
Stand alone electronic temperature sensor: 20,8 degrees C.
The THGR328 devices are less consistent and reliable in their measurements compared to my other temperature devices. On average the temperature reading is 1,3 degrees Celcius lower, the humidity reading of one of the devices is +/- 10% lower. But fortunately, this can be compensated in the RFXCOM Homeseer plugin by using the calibration value.
