Thermostat reports higher temps than remote sensors

Does anyone else’s main unit report higher temps than a nearby remote sensor?

After setting up four remote sensors, I noticed that the main unit always reported one to two degrees higher than all of my remote sensors. I was curious about this so I purchased one more remote sensor and installed it six inches away from the actual thermostat on the same wall and sure enough, the remote sensor reports 1 to 2 degrees less than the main unit.

Anyone else experience this?
