Temperature sensor location

Where in the unit is the temperature sensor located? Does the mounting orientation affect its airflow / readings / accuracy! I noticed the unit gets somewhat warm, and it’s temp readings are correspondingly higher than would be expected.

The temperature reading on most units is definitely higher than a true reading of the ambient air temperature, although it is almost always a fixed number of degrees. There is a website change coming in a month or so that will let you set an adjustment factor for the temperature reading (allowing you to calibrate it back down to ambient level).
