Feature request - save altitude for a location

Sounds interesting, lets make it more easy. Allow to save heights for registered WiFi networks. Usually HomeWifis are stationary, so whenever you sync your watch at home it could auto correct the height.

Only a few models have wifi. I believe a better approach would be to adjust elevation in a proximity of a GPS waypoint with known elevation. For example you set Home as waypoint; when you start (or end) your run close (+/- 10m) to home, the elevation adjusts. I actually thought this is already enabled in some devices.

I'm pretty sure it is already there undocumented (at least it was present on fenix 3).

If you let the unit get a GPS fix and then calibrate the height for this position.
The next time you start a session and you get a lock near this position it autocorrects the height from the stored one.

Auto cal. on the fenix 3 only calibrates the altimeter automatically at the start of an activity based on location proximity. It does not calibrate the altimeter when restarting an activity with "Resume later". It does not calibrate the altimeter when passing through the location of a previously saved calibration point during an activity. It uses the list of "Saved locations", but it also uses a hidden list of previous manual calibrations that were performed either using the Settings menu during green ring fix, or during an activity.

In-activity automatic calibration to previously saved locations and calibration points would be a nice feature though I agree.

Submit it here perhaps?

Yes, my F5 definitely does this (most of my runs start from one of two points near home and work, and it autocalibrates every time after I calibrated post-fix).

I live three floors up, but my F3 could catch the WiFi from outside. Bit of ambiguity there.

You're advocating a system which works only if you explicitly sync and make sure it's on the same floor as where you calibrated.

The existing system based on GPS location is probably better as it will work whenever you turn the GPS on at a known location. (To be fair, if you leave your watch on an upper floor balcony to get a GPS lock before heading out, it may have a similar ambiguity problem - not sure how the F5 deals with that. I'll check.)

I made the assumption that the proximity required for Auto cal. was in any direction (including vertical), but I haven't properly tested it. It will be interesting to confirm.

I think you're right that there will be a limit, but I think three floors up will be too small to trigger that. I'm interested in seeing what it does if it sets the elevation to the calibrated value when I'm three floors up, then head out without starting the activity - will it follow what the barometer tells it, or stay locked to the calibrated number?

Well, I guess a first world problem, but it ought be be trivial to provide some functionality to simply store a location height - let’s call it “home”, and then calibrate the altitude without having to go outside to get a GPS fix... The benefit - if that’s not too strong a word - is that barometric pressure is then adjusted too. So, for example, I know I live at 140 meters but my Fenix thinks I’m at 116 today - so the barometer is reading too high. Another “solution” would be for the Garmin Connect app to simply tell my Fenix when I am at home - all Android and Apple smartphones are geospatially aware - and set the correct altitude when syncing.
