We have two 3rd generation Nest Learning Thermostats sitting 4.5 meters apart on the same wall. We have two thermostats in the same room because we have two zones of electric underfloor heating in the one room and it is useful to be able to control them separately.
We've had this set up for five or six years and been very happy with the way the Nest work in general.
One minor annoyance is that one thermostat always shows the temperature to be hotter by about 1.5 C and The humidity to be higher by about 2%.
Is there a way to fix this?

Thanks for the reply.
The Nest Thermostat works independently and could provide a difference in temperature or humidity reading depending on the location and other factors such as electronics and appliances near it.
