Two devices: how is RHR calculated?

Hi,

I wear two devices: Fenix 5X and Vivosmart 4. The later is my dedicated tracker.

The resting HR in Garmin Connect is neither the value from my Fenix nor from the Vivosmart. Is it the average from both devices?

Thx

    I do not know how it is with mutiple devices, but with a single one, the daily RHR in Garmin Connect matches the RHR on the watch. If you wear two devices alteratively, it is quite well possible the values are being combined, though I do not think they are simpy averaged, rather the time may have impact too. It may be also important which of the devices you wear during the sleep (if any), and whether you wear any device (or both of them) more than 4 hours in a day. Some hints are written in the following document, though the exact algorithm is not revealed, and there is also no comment on multiple devices: The TrueUp option can have perhaps also influence.

    That's a good starting point. I wear both devices all the time on different wrists.

    Please find an example below. As stated above, I wear the devices on different wrists.

    Your Garmin Connect shows the same value (RHR of 69 bpm) as your Fenix, so no average. You can also compare the 7-day average shown on the watch (63 bpm) to that in GC (Health » Heart Rate » 7d » Averages - Resting).

    When you go to the device settings of your Fenix in GC and then to the settings of Vivosmart, is the option "Preferred Activity Tracker" enabled only at Vivosmart?

    Thx for looking into this. I think it was just a coincidence. I just took another screen containing the weekly RHR:

    So Tue, April 14 is today (D stands for Dienstag = Tuesday)

    Only the Vivosmart is my dedicated fitness tracker. You can only select one at a time. TrueUp for the Fenix is enabled.

    Turn off the HRM on Fenix for a few days, to see whether the RHR values in GC will match the Vivosmart better.
