SSWHRB Wrist HR Poor Since Latest Update
-
@Darren_M Do you run outside I’d imagine? What’s the weather like?
I would say the third run’s heart rate work up looks pretty legit to me, though it is then followed by a big drop, which is clearly not really supported by the pace data.
It’s interesting because usually the sensor would do the opposite: it would mistake your cadence for heart rate. So, you get real high numbers in the beginning, which would then level off. If you switch from pace to cadence in your charts, are there any correlation?

Keep in Mind that the colder it gets the worse OHR gets I think this is what we are seing here:
-
• When exercising in cool or cold temperatures, your body attempts to keep your body temperature stable by directing the blood flow from arms and legs towards the core of your body. This reduction in blood flow to the arms can make it more difficult for the sensor to measure heart rate accurately.
• If you frequently have cold hands, a proper warmup before exercising may be needed to improve the accuracy of heart rate readings -
@NickK Most of the time it struggles to see an increase for many minutes, other times as with the third graph a brief pause in pace, which would result in my real HR falling slightly, totally collapses the HR reading which then fails to recover for many minutes.
Also the third graph shows that @Dimitrios-Kanellopoulos theory, which I totally agree could cause problems if I was cold, can’t be the problem, because I’m already warmed up when the HR collapses and is slow to recover. I’ve also completed every run in December in a waterproof jacket with taped seams with a base layer underneath. I won’t hang around long enough after leaving the house to allow my body to cool that significantly for this theory to come into play. I’ve also read a post from @nassosc who’s had the same HR issue indoors on a treadmill. I ran through November and until I updated I had very few problems.
I appreciate the replies though!

I received another reply from Suunto after they allegedly escalated my issue. At no point did I ever mention it was a HR strap issue and quite clearly stated it was wrist HR since the last update! Im right in thinking that none of this answer is relevant to wrist HR? Anyway, Happy New Year to everyone, wherever you are!
Here’s the answer below: -
We would like to let you know that if the HR readings are inaccurate it might be because electrodes are not wet enough. It might be as well because the belt is slipping.
How to proceed:
Use gel instead of water if that was not done yet, put some water on the chest and moisture both sides of the textile strap.
Wear it tighter if you haven’t tried yet or if it’s not too uncomfortable.
Change battery, this can always be an issue.
Hope this helps. -

@Dimitrios-Kanellopoulos I’ve been asked by support to do a hard reset. Is this the full factory default or the procedure known as a soft reset, which I haven’t been asked to do at all?
If it’s the factory option, should try a soft reset first? Or is none of this going to work?
Many thanks,
Darren -
“factory” it’s not “soft” reset
You can try a soft reset, but if support suggested a full reset , probably it won’t be useful.

Thanks. I’m guessing I’ll only lose the log, my personal data and the bluetooth pairing. All my custom sports modes should just sync from Movescount, yes?

@Darren_M
It should, but let’s wait a confirmation from someone who already did it.I did a re-flash some weeks ago, but it’s not the same as a factory reset.
-
Cheers buddy!
I’m going to check if the soft reset I did makes a difference. So tomorrow, I’ll do a short run and I’ll know straightaway!
Thanks!

My SSWHRB is producing good HR data after a factory reset. I’m not sure why Suunto support felt the need to play games for 4 emails before giving me the solution. However, it’s good and I’m happy. Just thought I should report back with the conclusion to the issue.

Having similar issue and just want to be clear soft reset did nothing and factory reset fixed it? Thanks

@fritzbt2013 That’s exactly right!
