Default is disabled. Probably you had an update/reset and the option to display and log it is now disabled.
Hello, thank you for your willingness to help.
Iâm lost, I donât really understand what default exclusion you are talking about 
I have these settings:
regards
You have the necessary options enabled
But to avoid that you get paired to someone elseâs HR strap, you should set the BLE ID of your own strap here:
Then check the IQ field to see if it displays HR and Power. If it is, it should work.
Do you recommend changing âClosestâ to âLastâ?
I have a little training in the afternoon, so Iâll come back with an answer if something has been fixed, even though I havenât changed anything, and you say that âit should workâ 
regards

Closest (ble) or ID=0 are intended to allow initial connection. After this firts connection you should change to Last (ble) or your sensorâs ID for ANT. That way you assure further connections are established only with your HRM.
There are certain conditions that must be met in order to calculate readiness like at least 4 activities recorded with this device within the last 21 days.
See next link for more details

Hi.
From the page you have provided, the conditions I have (rather) met.
I have been using AlphaHRV for ⊠probably its beginning
The data quality certainly does not exceed 10% artefacts.
I have an average of 4/5 cycling activities per week.
Over the last 21 days I have 12 workouts.
Hmmm, in theory I meet the âtechnical conditionsâ and until last Wednesday normally âRaâ worked.
Today it still showed nothing 
regards
Artur
Now a thought occurred to me, although at first glance it doesnât seem to be related to AlphaHRV, âRaâ
Well, the lack of display of âRaâ has occurred with me since 10 April (9 April was still OK).
And it was on the night of 9 April that âZwiftâ turned on the counting of outdoor activities into a pass, it also introduced fitness statistics.
The second thought that occurs to me now is that in order for outdoor activities to be counted, the âGarminConnectâ had to be unpaired with the âZwiftâ and then paired again. And this I did on the night between 9 and 10 April.
I havenât had a âRaâ since then 
Looking in the activity history, today was the 4th activity from this activity with the unpairing of âGarminConnectâ with âZwiftâ.
Hmmm.
On common sense it shouldnât matter what configuration GarminConnect is synced with other platforms.
Unless I am mistaken.
alphaHRV keeps a local copy of previous 21 days activities data needed for readiness computation. These data shouldnât be affected by any change you did to the link with Zwift. Only uninstalling/installing alphaHRV could clear the activities data history.
Anyway, lets see if next activity (5th since the issue) shows same behaviour.
If the issue persists, send to me the fit file of one of the affected activities. I canât check the reference data, but maybe the activity provides some clue
I think Polar changes the id of the BLE periodically. I have like 5 in the watch that are all my H10, every now and then my H10 doesnât pair to my phone and needs to be paired again. I think Garmin just pairs to the closest ble.
I also donât have the alert panel, but I do get the Ra displayed afterwards in GC and in the file. I checked that show alert panel is enabled in ahrv settings.
I will, of course, let you know how the situation develops and if âRa is backâ
The BLE id changes when you remove the battery. I havenât seen the id changing at any other condition.
The Ra alert is shown only if alphaHRV is visible. If it isnât, move to the alphaHRV screen when the alert sounds.
Edit:
Firmware 3.3.1 fixed ble adressing change
Hmm⊠I donât think the BLE id changes, the id is printed on your H10 and remains fixed.
But, if you remove the battery, the H10 is set back to default and that means that only one BLE channel is active. You have to connect with Polar Flow and re-enable the dual BLE channel option.
Depending on which channel you were using before, you may need to pair it again.
What I did is, pair it to your Garmin device while only one channel was enabled. That makes sure that even after a battery replacement, it will connect again to your Garmin.
Then I enabled the dual BLE channel and while connected to the Garmin, had my phone search for it. Then paired it on my phone on the second BLE channel.

Hello everyone. Iâm using the **Garmin Fenix 8 and the HRM Pro Plus. For me, itâs important to get running power data from the HRM, but I canât seem to receive both power metrics and alphaHRV readings at the same time. Is it even possible to use both running power and alphaHRV data simultaneously?
Is this only happening on outside rides, or also on indoor rides, or everything?
For me, most of my weekend rides (outside) donât show any Ra value, which I queried in Sep-24.
It does not show âRaâ for either indoor or outdoor activities.
As I wrote above after analysing the circumstances in which it stopped displaying âRaâ for me was exactly the moment I unpaired the Zwift from GarminConnect (and paired it again after a chiwli) - to make the former count outdoor activities as a pass.
Today was supposed to be the fifth activity since that moment, but⊠as if out of spite, since time immemorial the Edge has rebooted after a few kilometres, and after that the âRaâ could not be calculated in any way.
Well, Iâll have to wait until Friday, as I have a busy afternoon tomorrow and wonât be able to do anything.
Thanks for that information. I had noticed a single BLE channel on my H10, but assumed that was the norm
Itâs the default. I think it uses less power then and the battery lasts longer. But most people want 2 channels anyway and CR2025/2032 are cheap.

H10 has CR2025.
Disconnect the sensor from the strap when not using it, otherwise battery drains rapidly. This is probably because you can use the H10 stand-alone for short periods. It records internally and you transfer afterwards. My guess is that leaving it connected to the strap, triggers unwanted recording. Itâs just a guess, but if you disconnect from the strap, the battery lasts 3-4 times as long.

The only difference between the 25 and the 32 is the thickness. 2032 is 700 ”m thicker.
Yes, but that little extra thickness can make the difference between perfectly water-tight or not. I donât want to risk any sweat getting inside the sensor.
