Software 20.00 Altimeter and Auto Calibration

Agree. I live on ground floor.. but now my watch sais I'm 93m above sea level compared to 63m.

Why change something that works? And how come I live 30m higher now?

Altimeter drops to zero every night. Garmin what was wrong with manual calibration? It worked fine and I want it back!

For those with problems I wonder if it would help to manually save a location at your property with the altitude set to your preference. In theory this might/should override the DEM reference that Garmin uses for those coordinates. Maybe if you sleep many floors above ground level you could even bake in your own correction/adjustment to the DEM.

Personally my overnight calibration are close to, if not exactly matching the DEM value around my house. Yes, I sleep one floor above ground level, but I am OK with a 4m discrepancy when I understand the mechanics of the calibration function. FWIW I have also saved my own location points outside the front and back of my house, just to help solidify the numbers.

When I go for my daily dog walk the Garmin DEM shows 15m in the car park. I have saved a couple of locations in the car park set to 17m, which I believe to be more correct. The watch always seems to start out at the 17m altitude that I've saved, even if I started GPS soaking some way away on my journey to the car park.

This is all on 20.00. I'm using Auto Cal = On and Sensor Mode = Auto.

Sadly, things are still not perfect - my car elevated by 3m while parked for 45 minutes and my house sank by 16m by the time I returned home, but at least my overnight calibration and start of activity calibration are good.

I have tried several times to manually calibrate the height in my apartment on my floor. But it doesn't help, and every night something goes wrong.
Maybe it's because my workout usually starts near my house, but at ground level. It turns out that two points with different heights are very close.

Several nights passed. Never once did the night auto calibration set the correct altitude. More often than not, she lowered me to ground level. But several times she lifted i into sky, above the roof.

Tonight the clock showed that I had climbed from a height of 226 meters to 620 meters. Where does the clock get these strange numbers?! Garmin, please turn off forced autocalibration. Obviously, it only makes things worse very often.

I didn't sleep tonight and the altimeter did not automatically calibrate. This is victory!
