Hello,
I noticed that when I track an activity the speed and location are definitely based on GPS satellites however the altitude is completely wrong probably based on barometer? What's the point of this feature when you have GPS?
I hiked from 2200m to 2300m and it shows I went from 2000 to 3100 with all kind of up and downs in-between. Can I force it to use GPS for altitude?

I have the Bip S and this device has no baremeter anymore and it shows no altitude at all after recording a training. I asked the amazfit support exactly your question. Here the answer:
"As I know, the altitude data recorded by the GPS sensor is not very reliable. So the unreliable data will not be shown in the app. Hope you understand!"
The good side: A lot of tools are adding altitude automatically, e.g. when I upload the .gpx without altitude to Strava, Strava adds automatically the altitude according the location. Or you can add it by yourself with https://www.gpsvisualizer.com/elevation Maybe you can "fix" your altitudes like this.
How do I get gpx data once the recording is on the mifit app?

Ah yes, with Bip you have MiFit app, this app does not have the gpx export feature.
With Bip S you have to use the "Amazfit App", there you have the .gpx export feature or the "sync with Strava" feature. I am not sure if you can use the Amazfit App with the old Bip, I think I have read that it should be possible.
For me it is still strange, that they have two apps doing more or less exactly the same....
Insnt it more strange that they can track location and not altitude? Like it's much different of a calculation when you have satellites.

It tracks altitude, but it is not displayed. The support is not that wrong with the answer. There are a lot of articles in the internet about accuracy of gps vs barometric altitude. e.g.:
https://geoawesomeness.com/accurate-altimeter-gps-watch/
For GPS it depends heavily if you have a good satellite constellation or not.

It's possible add a activity for gym workout in amazfit?
I'd be very interested in having that as well. As of now, with firmware 1.3.4f, the list of activities that you can track is really short: Run, Walk, Run indoor, Bike, Bike indoor, Trail run and Elliptical. When I used to have the MiBand 2, I'd have continuous HR on and track circuit training in Endomondo. Now, unfortunately, I am unable to do any of that
Any ideas if there's a way to:
- add more sports activities to the Sports tab?
- track circuit workouts in any way, ie in Endomondo?
Thanks

Continous HR is available in Amazfit, whats stopping you from doing what you were doing earlier?
Well if I log a circuit workout in Amazfii it doesn't get exported to Strava. I think I read somewhere that it only exports workouts where you get GPS fix, ie. when you're outside. Other than that, I'm too cheap to pay 50 bucks for premium Strava if I had that for free in Endomondo...
I'm in a similar boat, don't really want to pay premium strava, but thought that maybe I could use the "Elliptical" training mode for my gym workouts to track time and heart rate. I didn't realise you couldn't upload the workout itself somewhere after training though to analyse the heart rate graph if you wanted to for example.
@kopaczus, how do you currently track / log your gym and circuit sessions?

You are not the first that want's the non GPS activities
Thank you @fzelle
I don't have a watch yet, doing my research but I'll definitely look into this.
I'm sure I'm not the only one who wants non GPS activities or gym workouts. Hope this at least resolves the strava integration!

Although non GPS activities are not uploaded to Strava they can still sync to the Amazfit App so you have a record on your phone of riding time average HR and kCal burn.
Yeah, but that's useless if you have all your workouts in a single tracking app - Endomondo for me - to analyze your performance and plan ahead. Amazfit app is okay, but doesn't cut it.
Hi all,
I don't know if this already exist or if it is even possible from the technical perspective. I've tried to find how to do it, mainly trying to install one of the already existings apps for android but only one is compatible with the amazfit pace architecture and the result in the watch screen is to poor.
The point is to have a new activity in the smartwatch that record laps by GPS position (fe some garmin models do this as well). You set at the beginning a start point and every time you cross that point the activity set a new laptime. It will be usefull for different sports as for example circuit cycling or motorsports like go karts/motorbikes.
Does someone know if this is possible or if already exist something similar?
Regards
Which device? Pace and Stratos have a function called Autolapse which I guess is what you are looking.

Hi nhedgehog, thanks for your reply.
I have an Amazfit Pace... I can see the autolap by distance or by time but can't find the autolap by gps start position or something called autolapse, where is that? Do you have any custom rom installed?
I don't think you can do it besides auto lap by distance or time, as most watches do. If you need anything else then probably you must export the GPX data on watch, transfer it to computer then use a third party service to edit the data.
I'll answer later, just switched the ROM, don't know if I got confused with all that new settings.
I'm on the Amazfit Pace Chines BETA 2.0.6.12 ROM. Here is a thread which lists the activity settings of some outdoor activities.
You are right I can't define a GPS position as Lap Starting. I have the possibility to define autolap by distance and set this alert on or off but not what you were looking for.
I also would be interested by this GPS lap function
WOS2 on Pace has an "Auto Lap" setting (with option of notification separate from the normal lap notification where you can set the lap length), most probably it exists on Stratos as well... Does it do what you need?
Hey, i just received my Bip and synced correctly with iPhone, but when i workout at gym or somewhere, it doesnt save the HR to calculate the burned calories and other aspects, is there any app or something? Because I think that the Bip only uses GPS to estimate pace, but not the HR monitoring.
Sorry for my English, hope you understand.
As far as I know, all Amazfit watches record HR during activities: BIP, Pace and Stratos. They won't use it for calories burnt for common steps (not in any activity) so far. Are you sure your HRM is working? Can you get an individual measurement with the watch?

How can i access to that measurement with ios? Through the health app or with the mi fit app?

You don't need the app to check if it's working, simply do a manual measurement using the watch. Can you get a value? Does it look reasonable?
But to answer your question, MiFit should display all HRM data after a sync, at least this is how it works with Pace and Amazfit app.

Yes, i did a manual measuremente and got 53, but for example, i workout without running, and with 1 hour of training it says 2-3 calories burned, and that is not logic.
If you get bad HRM then it will result in non logic calories burnt data as well... And if you get bad HRM with other person using the watch then probably it has a bad HR sensor and should be replaced.
No, i think the measurement its correct, i tried with several persons and the HBR is correct, but its not used for burned calories, or i dont know how to apply it.
Amazfit watches use a very basic algorithm to calculate burnt calories due to daily steps, it doesn't use HR, even if continuous HRM is on. HR is only used for recorded activities (and even then it seems to be underestimated).
Hi everone,
I am using Amazfit Stratos, Rom version 2.3.4.0 .I have a climbing activity on 1 spetember 2018.
The total mileage shown on watch & Amazfit App is 15.1km, but it only 12.2km (12.6km if consider 3d distance) via Strava or Google Earth after I download the gpx file, it is 23% different. The huge mileage different also happened when climbing mountain with elevation more than 500m, the others activity will have 3% to 6% different (the watch reported higher).
Anyone have this problem? How to solve it?
Is anyone noted that the elevation info always missing in the first few point of the GPX file downloaded?
Probably you had 3D Data on (search for what it means).

Yes, I know what is 3d data, I have set 3d data on for this climbing activity.
But it is 12.2km (without consider 3d) and 12.6km (with consider 3d), calculated by myself and checked using "Google Earth".
Will it because of movement of the hand where I wear the watch?
Sounds like a problem with the altitude measurement. I'm not happy with that too. Opening compass, doubletapping on it and waiting for a GPS fix before starting an activity is helping a bit.
I see several reasons for this:
1) The phone app is smoothing out the altitude data by using digital elevation map data, which at the end comes to different mileages.
2) In the mountains unprecise GPS signal can lead to significant differences, 30m 2D can sum up to 100m or more 3D, a balance between weak signal filtering and loosing signal is not easy to achieve.
3) During my tours I had another GPS running parallel. What made a real difference was, what I wrote under 2) and that my Pace did not exactly recognize pauses, which resulted in several pausing clusters which added to the mileage.
My conclusion:
I'm using the watch but after the activity I:
1) export it to tcx format via the exporter available in this forum.
2) manually delete the first trackpoints which either have no altititude or an unrealistic speed.
3) correct the altitude with external tools if I see it necessary.
Some of this after activity steps are done by the phone app automatically. Since the phone app is not giving me options for this I use other tool to know exactly what is going on.
Edit: The handmovement shouldn't influence outdoor results.
Did you check the altitude graph? It seems that run/walk use GPS for altitude whereas trail run/climb use the barometer. I still think it's related to 3D Data: the higher the altitude change, the higher will be the final difference in distance when compared to common "2D" data.

Also, latest international firmware for Stratos is 2.3.6.1, and you are still running 2.3.4.0... Latest Amasfit app version may make a difference too... Auto-pause may make a difference too: either disable or use something other than "stand still".

Are there other settings for Auto-pause than "on/off"? If so, where can I find them on the pace?
Profil Climbing and profil Trail Running have only Auto-pause "on/off" on ROM Pacificator WOS 2.6.3.1.

Not all activities have the other options, then you can try disabling it and use the button to pause manually. When recording walkings I found that it was too sensitive and it added a lot of bad data points to GPS when enabled.

I experienced the same phenomena. Thats why I stopped using "Auto-pause" and was wondering now about the possibility of finetuning autopause. Which activities have this, I couldn't find any?
Edit:
I found one: Cycling (1km/h steps)
Thats understandable but with the bad HDOP&VDOP filtering the Pace has, configurable Autopause in 0.1km/h steps could help in other activities too.

Run has an settings based on pace, Outdoor cycling has it based on speed. "Common" walk doesn't have it, it's either on or off.

the firmware now is 2.3.6.1 (2.3.4.0 is when that particular climbing activity on 1 september ),
I always off the 'Auto pause' except the first time i use the watch, because it keep on pausing (because my activity is inside the forest).
https://drive.google.com/open?id=1KSCwCRNmbnLdRgJaI1x9lkoogJN0Qv25
this is the list of all my activity, it is true that '3d data' will affect the total mileage. When I on '3d data' to climb the mountain, the total mileage is 20+% higher, but it is 3 to 5% higher when only the small hill.
However, activity after 29 september , '3d data' is set to 'off', the total mileage still 3 to 5 % higher.

those are the elevation profile of activity on '1/9 climb 3d-on', '3/11 walk 3d-off', '10/11 run 3d-off' & '17/11 trail run 3d-off', it seem that all altitude record by Amazfit is lower than which corrected by 'Strava' or ' gpsvisualizer.com' or record by handphone.
Any solution to keep the total mileage within 1 to 2%? after off the 'auto pause' & '3d data' ? 3 to 5% is still consider too high.

Having a look at your pictures your altitude data is much better than that what my pace produces before this was "corrected" by the phone app.
I guess that means it comes from the phone app.
So that leaves us 3 options:
1)
Those 3 altitude correcting sources you use:
Amazfit
Strava
GPS visualizer
are probably using different altitude maps - meaning you can't compare them and have to decide which one you use. I guess the one from amazfit
has a lower resolution compared to those from Strava&GPS visualizer. You probably can't change the altitude mapsource of those 3 apps - just decide which one you prefer and stick to it.
2)
If I'm using altitude correction I don't rely on either of those apps but use LIDAR maps which have a higher resolution and therefore representing the altitude of the area better:
http://data.opendataportal.at/dataset/dtm-germany
To do that I need the RAW data from the watch, which I get as mentioned via a python script as tcx files directly from the watch. Edit: One could use the gpx file which the watch procides under activities but the program I use for reprocessing the track does not recognize the included heartrate data. Otherwise internal created gpx and external created tcx don't differ much.
My resolution: another app
3)
The third option I see would be relying on the altitude data the watch provides, which I personaly found not reliable at all. I guess that has something to do with the filtering of weak signal from the gps chip, which is done by the gps firmware. To solve this problem we can only hope for some better filtering via GPS firmware by the manufacturer.
Hello,
I recently purchase Amafit Stratos main for sports activity and good GPS tracking.
My decision was made according many good reviews but what a surprise?
After several activities i was very very disappointed by its GPS tracking, im on latest 2.3.7.0. ROM.
For example walking only 6km, it was off bu 200m.
The gps map was showing gps drift and bad road tracking, i was compare it with polar m200 and garmin fenix 5.
When it upload data with Strava non of data didnt match, i mean total distance and every km i run.
I even make factory reset, but results was the same, bad unprecise gps and different data with strava .
So i search again on net for someone like me complaining about bad gps accuracy for stratos but nothing found!
Please help.
