I have had two 3rd gen nest thermostats for several years, one is attached to the wall, one is on the stand. These have always failed to read the correct internal temperature, introducing an error of about 1° - 1.5°. I work in the field of thermal engineering and Building Management Systems and have precision thermometers, so I am sure of what I am saying. It was useless to have followed the various guides and contacted support (one of the two thermostats was even replaced). After a long time I returned to the community and it is amazing to read how many people have this problem that was never taken seriously. And to think that the remedy would be really trivial, all it would take is to be able to run an offset. But Google is deaf because I see that many other suggestions also fall on deaf ears (reports and schedule management are also really poor). I must say that this is very frustrating, not least because we are talking about Google and a thermostat that does not come cheap. I now have them installed and manage the setpoints by increasing the desired temperature by 1 degree from the actual,
Someone from Nest explain to me, but what is the problem with inserting and managing an offset?
