Temperature sensor Inserts (Temperature-humidity-motion, temperature-humidity, or Air Quality) may show a value that does not match temperature values in other thermometers, smart devices, or thermostats. There are a few reasons for these discrepancies which will be outlined in this article.

Initially, the temperature sensors in the Inserts take some time to calibrate. You can choose to complete an automatic calibration by allowing the Insert to come up to ambient temperature while occupying the device. 

The temperature values can also be affected by the sensor's proximity to fans, vents, or exterior walls. Host Devices installed in exterior walls can affect the temperature observed on the temperature Insert because the sensors are in the transition area between the outdoor and indoor temperatures. For this reason, we suggest that a manual calibration be completed for sensors installed in exterior walls, as well as those that may be affected by other devices that could be impacting the temperature. For best performance, it is suggested that the Swidget temperature Inserts are installed on interior walls away from fans and vents.
