HRV Status and sleep tracking not working

Is heart rate and stress recorded at night?

As of last night no. Seems the HRM has died.

Did you check the battery saver settings? Maybe it kicks in during the "sleep hours" and modifies your wrist HRM settings, there`s a setting for that.

Does the HRM work during the day?

Hello,

I have similar issue - Fenix 6x Pro, no sleep or HRV data available in GC for last 2 nights, yet it is visible in the watch. It seems that my watch stopped syncing those 2 data. Firmware 24.00.

My F6x has behaved quite OK in sleep/hrv data recording since the end of the introductory period of all night hrv, I could even manually end the sleep, which I did sometimes, but today I got no sleep data.

fyi today I did not use the manual end of the sleep option, neither in sleep widget, nor in training status/hrv sub-widget menu item.

fyi2 my hr was measured and recorded during my sleep, too.

I am on 24.10, but not from yesterday and I have no clue what happened. It is the first time my sleep was not  recorded.

Sidenote: after having a recorded activity with my Edge I used the wifi sync on my F6x to see the Acute Load properly on my watch, too, and I got a strange message. It was not a simple “sync failed, but something like “1 file not transferred” or similar.

The second wifi sync ended in “sync complete”.

It is just me whose watch thought that a sabotage in sleep recording just before the first night of Christmas period would be the proper message to his/her owner?

I'm running 24.77 alpha firmware and, twice since installing, the watch has recorded overnight sleep correctly, only to replace it later in the day with a ten or fifteen minute sleep while I've been completely awake. 

Factory reset means I don't have a baseline for HRV Status,, but it is tracking through the night.

I have raised a bug in the alpha/beta forum.

I too use the alpha 24.77 and was happy to see that finally the battery saver bug was fixed only to now be replaced by a pairing bug with headphones :(
But my sleep at noon (about 20 -30 min) did not replace my previous night sleep until now.
HRV was also recorded every time during the night and is within the baseline.

Thx to both of you.

Of course, I did a couple things yesterday but almost of all these were a soft a regular moves.

Maybe there was one thing that I had not done for months: I modified the end time of the measured sleep period, because I thought it was too late, and it was simply fake, I was sitting in the bed for hours.

And I did it on Thursday, but for the night between Tuesday and Wednesday. 

So who knows what I caused. But I will make another try after a proper hrv/sleep logging. I mean I will modify the sleep time.

I chatted with CS and they had me reboot by turning off and turning back on. That worked. watch is tracking again like a charm. 

Interim report: without intervening anything hrv/sleep were recorded (I applied a manual end, btw)

Hmmm, can it happen that a daytime blank sleep data replaces the properly logged nightime sleep data?
