Nest Thermostat lowering heat temperature at night

[Canman]

Why would my learning thermostat automatically lower my heat temp during the night?

Every morning I wake up the heat is several degrees cooler than what I set, and want it set at. Is there a way of holding the temperature during the night?

I never adjust the temperature down manually until around 8 AM but when I wake up around 5AM it's always cooler and I have to raise it manually. I am perplexed why it would lower it during the night and not "learn" that I do not want it cooler until later in the morning after we all get ready......and when I then lower it.

I do not want to disable the learning feature since it's one of the main reasons I invested but I'm starting to get annoyed.

Frimware 6.2-22 seems to have created a huge issue. In giving Google through Friday to fix it or I'm getting of the Nest. It's been great but not fixing this given the weather is ridiculous. 

Just push out the old Firmware for crying out loud.

I too had this issue and someone on another thread suggested to turn off the safety temperature settings and that has worked for me so far. It now warms according to schedule all day and night (as well as any manual increase/decrease). I live in Georgia so that is not as big a deal for me as it would be for someone who lived in a much colder state/location.

I have also seen in other threads someone suggest that you simply remove the device from your account and then reset it completely, go through all of the settings to reconfigure it as if it were a new installation and finally added back to your account. That seemed to work for some others. If you have not tried either of those I would suggest giving those a try.

Apparently it seems to be some glitch with the software/firmware version 6.2–22 Good luck!

UPDATE 01/13/22 - Stopped working after a few days and went back to initial issue - unfortunately. Back to square one.

My learning one is on 6.2-27 and if I adjust the temperature In the morning, it displays a comment “for the night “ , so it thinks it’s night time in the morning and daytime at night even though it displays the correct time . I have another one of the same thermostat and that one seems to be working properly.
