Suunto 9: Turn off wrist HR sensor completely? And how to tell if Chest Strap is sending data?

[Maryn]

@Dimitrios-Kanellopoulos maybe a good idea is to hide option for OHR under settings.
Example.
You are using polar OH1 during long ultra. After about 12 h OH1 is dead and then you can switch to OHR via settings.

[Dimitrios Kanellopoulos]

@Maryn That would not work if OH1 or some other belt is recording HRV

HRV is time and that would not play well with HR If I understand correctly.

[Maryn]

@Dimitrios-Kanellopoulos understood.

I would also want to turn the OHR off entirely. For example if I go for a walk and don’t have the chest strap and want to save the route and the workout but not the OHR readings because they are always wrong and showing whatever and it messes up my recovery predictions.

It is now possible. You can disable it for each activity.

There is a reason for the watch not switching back to OHR (it will switch back to belt if belt is lost though).

Many people blamed the belt , when belt diconnected and OHR took over

Are you really sure about this feature - which I would love! - because on my Suunto 9 heart rate this does not work.
If HR has been started with external sensor and the OHR has been deactivated accordingly, the OHR won’t take over and reactivate in case the connection to the external sensor has been lost.
I just checked it with the treadmill exercise, the Tickr Fit, and switched the Tickr Fit off … stable HR-number, because it kept the last number on the display. And yes - latest official firmware.

@Shrek3k I am on second beer, but do you mean it didn’t reconnect?

@surfboomerang - Perfect thank you. This is close to the conclusion I was coming too also. I’ll look for that different hear icon with the bar next run. Thanks!

[Rich Price]

@Maryn - Yes, I noticed this possibility on and event by event basis. I would love to turn it off in general too. The bright lights when it sits in a bag is weird. I know it probably times out and stops doing that, but really I would love to simply disable it so that I can be sure it never records. It’s really not accurate at all from my experience.

[Maryn]

@Rich-Price so you mean switch off even if you go through the menu and want to check the altitude, for example?

[surfboomerang]

@Maryn I would love that.
I’m not using the OHR either, but it switches on automatically if I press the down button on the watch face. Even when I’m not interested in my heartrate.

[Maryn]

@surfboomerang what annoys me is that HR is first when I press the down button and sometimes causes slight delays when I try to get to altitude quickly.

Apologies … you are right, it reconnects with the formerly used HR-‘belt’!!!

Obviously I only read and understood what I wanted to see - when battery of HR-‘belt’ is empty (which is possible for Polar OH-1, Wahoo Tickr Fit and Scosche Rhythm 24), I would have loved to use OHR automatically.

[Dimitrios Kanellopoulos]

@Shrek3k no worries. I am asking also to know. There are intended behavours that can break…
