The humidity reading on my Aranet4 is off by 5% when compared to other hygrometers. I have a few by Govee and AcuRite, to name a few. I know calibration is impossible, but it would be nice to be able to offset the readings so they match with other sensors. At this time, I'm not entirely sure which sensor to trust.

Hi!
I checked the Govee and AcuRite sensors and it seems Govee has an RH accuracy of +/-3%, as does our aranet4 and AcuRite has +/-4% Accuracy. From the sensor measurments you can say, that the real reading is somewhere, where all the sensor accuracies overlap.
All of them are within each other's accuracy range so the readings are good and accurate within specification. No calibration is necessery.
