@timecode HR signal quality was probably bad in the last 10 minutes. If the R-R interval data is not good enough, then ZoneSense doesn’t work, at it needs that data. You can check the R-R data quality in Runalyze.
-
@timecode Or maybe the chest strap got disconnected toward the end, and the wrist-based heart rate sensor took over — which would explain why the data is there, but ZoneSense is missing.

@Ghost I don’t think that’s how it works, but I haven’t checked.
I don’t think there’s any switching between the belt and OHR. -

That’s true, no fallback to OHR -
@Ghost no that doesn’t work that way. Once the HR strap is disconnected there is simply no measurement - OHR won’t take over, unfortunately. It happened a few times to me already

Does anybody here use the Coospo H6? It is marked as supporting HRV, but I ran with it today with zone sense enabled but didn’t get any metrics. Don’t mind upgrading of I have to.

@James-Eastwood it is optical. For ZoneSense you need an ECG based HR monitor…

Salam… I use the coospo H9Z heart rate belt, it’s a heart rate monitor that supports HRV and so far it works perfectly with ZoneSense. -
@2b2bff it’s not optical, it’s a chest strap. Specs say it supports B2B HRV.
-
@James-Eastwood it needs to send R-R data. If it does it should work

@thanasis yeah that’s what I’m confused about. The specs says it does, it was connected (I think… I had paired it at least) but no zone sense stats, so wondering if anyone with the same strap has it working.
Speaking of which… any way to check in the data afterwards if the strap was actually providing the HR data (as opposed to the watch)?
-
@James-Eastwood Yes, I’ve been using one for a few months. It works fine with ZoneSense as long as you make sure the strap is damp.
-
@James-Eastwood Before you start an activity you can check where the HR data is coming from because the icon for the HR is different. I’d also suggest just turning off the watch OHR in the activity settings - it will then remember this for that activity in future.
You can also link your Suunto account to Runalyse which, among its many other excellent features and capabilities, can show you if there is RR data and the quality of that data within an activity.

@far-blue Great tips, thanks
-
@maszop As far as I can remember, on my Vertical, when the optical heart rate is enabled and the watch loses the signal from the strap during an activity, it switches to the optical sensor. But I need to double-check, because those saying otherwise here are starting to make me doubt. (I think I even decided to completely disable the optical heart rate sensor during activities to avoid that kind of annoyance.)
-
@James-Eastwood I’m sorry, I was mislead by the website cross promoting an optical arm monitor as well…

No, it does not, unfortunately. I just double checked. Once you start an activity, there is no way to change sensors, HR or otherwise. I’ve had it happen a number of times where the battery on my external HR sensor dies or stops working for whatever reason. You’re then left with no HR data for the remainder of the activity. It definitely should fall back to the OHR, but doesn’t.
I tie this in with the general failing of how Suunto handles external sensors. Hopefully the ability to change sensors mid-activity will come along with the ability to have multiple sensors of the same type.
