Altimeter issues with night calibration 11.28

Garmin, please get rid off the night calibration or add a possibility to turn it off. It only messed my altitude from right value to wrong 50m off altitude. I also got new watch because of another problem, but this bug is still present. Even if I ended my activity in front of my house with right altitude, this value get messed at night with auto night calibration. I was asking this long time before...

There is still another bug which I post many FW versions ago. If I go to sun rise/set widget from a watch face, scroll to map and return to watch face, the altitude on watchface is changed to altitude of place, which was on the map, no matter if I moved to completely another place with another altitude (without starting activity). This happens ONLY ONCE per day and if I open the altitude widget, the altitude jumps to right value.

    It's fixed. I don't know how but I'm happy; Bluetooth on or off does not matter, the watch seems to have learned  (cached?) at which altitude I sleep, just as the Fenix 6 'knows' that.

    Fenix 7 again set itself to groud level today, but now at 11:00 (AM). Sleep window ended long ago, I was at my desk at home, and had not been outside. Is that considered "nightly calibration" too or is something imvolved here?

  • Difficult to answer that one, I'm permanently connected to my phone and see no resets to ground level elevation.  Garmin wording in the manuals can sometimes be unclear and this statement:

    might possibly mean that if a weather calibration for 1 day it will make a "nightly calibration" out of scheduled sleep time...but I'm guessing here.

    Thank you, I guess that must be it. I read the whole paragraph in the manual again (a couple of times) and I can only conclude that this will never work correctly when one does not live and sleep at ground level.

    I wish I knew why the watch skipped nightly calibration for 4 nights, I thought it had "fixed" itself. 

    Oh well, I'll set a fake GPS location on my phone then. The top of a hill somewhere not too far away. (I just hate those breaks in the barometer trend, I  have had ABC watches since 2000, I am OK with the normal drift and used to manually calibrating a couple of times each day, but these abrupt trend breaks are annoying).
