BUG: OHR sensor crashes with non-ideal skin conditions (hair, dirt, small tattoo marks)
-
@Manuel-Extreme off wrist detection is not contact based, but somehow optical.
From here on I have no more ideas, sorry. -
This is the Vertical 1 sensor: it has been like this for 4 hours and has never turned off.
The Vertical 2 sensor: if it reads the signal incorrectly for 10 seconds, it shuts down until you intervene manually.
There’s no point in downvoting (-1) every time I report the issue. I will keep doing it until it’s resolved.

@Manuel-Extreme this will not just be “resolved”
Try placing your watch on a white/black/glossy/matte/etc surface and you will notice different behavior.
In your example the watch thinks it is on your wrist and trying hard to detect your pulse

Personally, I’m having the issues detailed here:
In my opinion:
-
22 milimeter wrist band is not enough for the Vertical 2 and Race 2. Suunto should go back to (at least) the 24mm bands in their next big watches (like Coros does with the Nomad and the Apex 4).
-
I think software algorythms are not clever enough with noise filtering when sweat or arm movements. I’m saying this because I had exactly the same issue with the previous Suunto watches and despite the different sensor.
-
OHR measuring works perfectly for me in both Garmin and Coros.
In Amazfit I have something very weird. In my left hand I have cadence lock but in my right hand OHR works perfectly.
No tattoos, no hair. The only thing is that I have low BPM while resting (that can be considered bradicardia).
My issue is exactly the same as detailed here and my profile very similar to that one (so, I’m not the only one): https://www.reddit.com/r/Suunto/comments/1on5qly/vertical_2_heart_rate_monitor_problem_not/ -

@Manuel-Extreme said in BUG: OHR sensor crashes with non-ideal skin conditions (hair, dirt, small tattoo marks):
Expected result
The OHR sensor should continue providing heart rate readings, even if signal quality is reduced. It should not shut down or stop recording data.Not my expected result. I rather have no data than incorrect data.
-
@elbee Do you really think 10 seconds of inferred data are better than 6 hours of no data?
-
You assume 6 hours of missing data was of perfect quality. And your demand was that it should always record data, regardless the quality. That last part I disagree with you.
And my personal, and therefore not very relevant, opinion: missed 6 hours of heart rate data? Not a big deal.
-
@elbee If I didn’t want heart rate, I’d have bought a Casio.
Maybe you didn’t read the post: the problem is that the OHR turns off without warning and doesn’t turn back on until you take the watch off your wrist.
-
There are 3 things
Should the the watch always record data even if it can determine the data is incorrect? NoShould suunto look into crashes? Yes
Am I less concerned with loosing some heart rate data than you? Yes.
My original reply is about the first point. But since it is an important point for you I will no longer capture your topic.
(Btw, I was not able to reproduce your steps on my race 2, so it could be model specific)

It seems that this update has fixed the bug. The OHR sensor has remained active for 24 hours without switching off.
