sometimes they send items that were returned by other customers, this happened to me quite a lot already
Things are moving further. A full suite of PC programs to track your workout with a complete single lead ECG on top:

This looks like a great step forwards - thanks for sharing. 
I will download this evening and try it out at the weekend if I can, even if just on one of my standard endurance rides.
Fired this up to try this morning but was not playing ball. It highlighted my ANT+ stick in the bottom right hand corner but did not recognise power and/ or HRM on graphs etc. I think I need to check with ANT+ drivers I have as per: Windows USB Support for Ant+ - libusb0-win32 | Fitness HRV
Will report back once I have done so again!
I reported the same on the YouTube channel. ECG over BLE is ok but no device detected over ANT.
Out of curiosity, what brand is your ANT dongle?
Its a generic one by a company called Anself.
Let us know if you get anything back from your comments on the YouTube channel please.
I have a Garmin dongle working with a multitude of other programs but canāt get it to work with Fitness Dashboard. Even after replacing the driver with the Zadig executable as in the instructions from the link you posted.
I PMād the guy on the YouTube channel and will post here if a solution comes up.

received My Polar H10 on Feb 2022. It just alerted me that its low on battery and looks like thereās about 190hrs of usage. I always separate the HRM from the strap after each use. Itās on a 2035 battery.
I have found that the H10 will sometimes transmit even if completely disconnected from the strap. The only solution was to remove the battery or it would only last 2 to 3 weeks.
Polar UK replaced the first device but the problem also occured with the replacement
If you see poor battery life run a bluetooth scanner to see if it shows up when it shouldnāt.
I also bought mine in February, and itās on 80% from 130 hours use. Strange that you say a 2035 battery, as the manual and battery cover shows 2025.
my mistakeā¦ itās a 2025 . havent changed the batt since I got it in the mail.
Mine doesnt show up using BLE Hero. But my Stryd does. (The Stryd never turns off. never)

Halleluja! As of this week I see HRV-rmssd values coming in from my Garmin Fenix 7. I assume it has to do with the new Alpha firmware I installed last weekend.
Anyways, makes me real happy. Now I can monitor and baseline my HRV daily values.
Excellent!

The only problem with disconnecting it each time that I have come across is that over time the button(s) may break if your not careful removing it each time. Luckily you can buy a replacement strap.
Me too since Monday on my 955, so I guess David has enabled it!
Hi. First of all, I read all the topic, because HRV is something that Iām very interested of.
I bought Polar H6 in 2013 and I used it to measure my HRV with EliteHRV. After a while the strap stopped working and I stopped using EliteHRV.
In October 2020 I bought HRM Pro from Garmin, because my main sport is running and considering it has running metrics I thought it should be good to understand the running mechanics better.
Iāve been training in MAF method since the end of 2019 and in the last 3 months Iāve been adding one interval training or a tempo run a week, trying to do 80/20.
Iāve been using HRV since november 2020 to track my health and recovery.
Questions:
-
What do you think about Garmin Strap? Do you think it is comparable with Polar H10?
-
And about apps to track HRV, what app do you think is more trustable to measure HRV? Iām using Kubios and EliteHRV and they have different results. I know I shouldnāt compare two different apps, but which one is more precise?
I also suggest, as told before, to separate morning HRV and DFA Alpha 1 in two different topics.
@david would it be possible to set āEPOCā on the Fitness page, so you can put it in context with power or heartrate over time? Thanks.
Regarding your questions:
- I had pretty good morning HRV results with Kubios + Garmin Dual HRM. No experience with HRM Pro. I havenāt seen any noticeable difference when switching to Polar H10.
- Polar H10 has the possibility to record ECG. I donāt think the Garminās can. The HRM dual for sure canāt. And that is important if you consider doing something with ECG. Fatmaxxer and now Fitness HRV are using the ECG signal.
- What are you comparing when testing different apps? Are you comparing RMSSD values (which should be very similar), or are you comparing Readiness (which you shouldnāt even bother recording)? I would be surprised if there were noticeable differences in RMSSD when using Elite, HRV4Training or Kubios. These are all top class apps, using the recommended filtering and artefact rejection. When it comes to the Readiness score, itās a different story. HRV4Training and Elite have an interpretation that also considers your subjective scoring. Kubios is not taking that in account.
There have been updates to the Fitness HRV PC app making it work with most off the ANT dongles and devices. Latest version has a tab to configure what will or wonĀ“t be used as a source.

Thanks! Time to give it another try then.
