Suunto ZoneSense

@Brad_Olwin can you help me with why this happens ?
)

While the app seems to be running it also shows waiting for data

Also the there is a big difference in the data in the watch ( eg I had some 5-6min the red zone ) while in the app the duration is 0

The watch is not receiving data.
The belt must record electric changes NOT OHR.
The belt must provide good R-R data
Delete and reinstall the Suunto Plus ZS app from phone and watch
At the beginning of your exercise 10 min of aerobic warm up is required before live ZS is displayed.

@Sportsfreund what belt?

@VoiGAS said in Suunto ZoneSense:

@Sportsfreund Yes, I have the same behaviour. After washing the belt the quality of the data looks much better, but still the live data just stays green. I ordered a new belt - maybe this helps.
I would also love to hear some long term real life experience with using Zonesense during the run

I have been using and testing ZS since last May/June. Is that long term enough?

Sportsfreund · 2 Feb 2025, 14:22

@Brad_Olwin Suunto Belt sowie Polar H10 belt. Both same. I can’t belief that you get real live values when all other users don’t get it.

Absolutly. How reliable are your live values on the watch? Can you use it to pace an ultra from the start or does it need more time to “swing in”? Not to mention the first 10 Minutes, its clear that it shows nothing

@Brad_Olwin @GiPFELKiND It seems that the issue is not occurring by removing fat burner app . Just FYI in case someone else finds themselves in the same situation
The watch does record the data btw

VoiGAS · 2 Feb 2025, 15:26

@thanasis Interesting, I had one SuuntoGuide running parallel. Will try without it.
Post workout data looked ok, so I think its not the belts fault

Sportsfreund · 2 Feb 2025, 15:54

@VoiGAS after training you are right. But not while training it is real.

2b2bff · 2 Feb 2025, 18:55

@VoiGAS I use ZoneSense with a Guide same time. No issues…

Sportsfreund · 2 Feb 2025, 19:38

@2b2bff In your case the graph shows all the time realistic values?
Really?

2b2bff · 2 Feb 2025, 19:44

@Sportsfreund TBH I don’t look too much on the time spent in different zones on the watch, rather in what zone I am currently.

Today I tried to stay in the green zone and had occational yellow on the watch. Looks similar in the App: 86% green, 14% yellow.

I never had a “waiting for data”. But I only started using ZoneSense a week ago, as I didn’t have a chest strap before…

@Sportsfreund

I agree; my watch data is never the same as the app data. I intuitively believe the APP data, not the real-time watch data. But I have lots of post-work analysis tools. The value proposition for Zonesense is the real-time data. It’s not there yet.

I used it pretty much exclusively to pace my first 100 miler in October. It worked darn near to perfection as my goal was to stay green the entire time (I am firmly mid to back of pack runner).

@stromdiddily so if you are suggesting that the app aligns with ten real time data you were shown on the app it may be that zonesense is aligned in real longer distances(??) . I am not there and I am running shorter ones .
In my case I have significantly different values between the watch and the app. I mean that in the watch I may have 15% of the time being on vo2max and the app to show 0%

2b2bff · 3 Feb 2025, 09:20

@Stephen-Kenny @Sportsfreund
I used today’s run to look a bit closer. The watch said about 08:30 in yellow. The App on my iPhone says 10:00 yellow and interestingly the App on my iPad says 13:00 in yellow.

But Suunto emphasizes in their videos that it is still early days, and they are going to improve it.

How long have you been using it? There is allegedly some calibration with each run used to make the real time data a bit smarter.

I am mostly running with an HR belt so I would say that I m using since it was announced .

Hi there!

Can you confirm for zonesense to properly work, you first need to put in some (how many?) workouts or minutes (which of both?) at each of the 5 zones? And basically ignore zonesense during this calbration workout(s)?

I’m asking as today I was running a 10k (probably my 3 workout with a HR belt and zonesense enabled) and wanted to do it in zone 2, but (almost) regardless of what HR I ran at, the DDFA-index stayed green:

On the other hand, it seems that zonesense was able to calculated my aet correctly, still:

This is a bit confusing to me. Any help is much appreciated, thanks!

cosme.costa · 2 Apr 2025, 11:24

@tschogo Theoretically you should always do the first 10 minutes easy, to do a proper calibration on each run. To have a good starting data in general, the first 3/4 runs with ZS, the whole run, should be very easy, but eventually everything will align if you do not do that.

In case of a race, you have two options:

1.- Do an easy warm up for more than 10 minutes and stop the activity, then do the race. ZS will use the warm up as a base.
2.- Only record the race, here ZS will use the last good calibration, from your previous runs/activities.

On each option the 10 first minutes will be discarded, option 1 should be more realistic because uses the base of the race day.

Regarding your 10 km, I understand that you wanted to do it in ZS zone 2 (yellow), I do not you as a runner and your paces, but from what I see it was a slow pace (1:20 for 10 km), so you should push a little bit more to enter in yellow. If we get used at some easy paces some times it is difficult go over this paces and we must also train these quick/effort paces, like starting doing short fast intervals or longer and progressive intervals with short rest times.

BTW do not try to match ZS and HR.

VoiGAS · 4 Feb 2025, 13:50

@cosme-costa But with Option1 you get a mix of warmup and Race Data. Would it be possible to switch from warmup to running with a multisport mode? Or would it start collecting data again after switching,
