Recovery Heart Rate is always zero

I recently switched to an Edge 840 from an Edge 520 Plus.  Since the switch, I've started seeing "Recovery Heart Rate" in my statistics (along with many other new values of questionable worth), but it's always zero.  I'm using a Forerunner 45 for heart rate data.  Is there something I should be doing to get Recovery Heart Rate results?

Edit: I checked activities on the Connect Web page, and they don't show recovery heart rate. So this appears to be an error in the Connect app, showing a field that isn't actually provided by Edge devices.

  • Do you see that stat on the Edge too? I couldn't find it in the post activity display. On my Fenix 7S Pro, I can watch the countdown from two minutes to the RHR display. I couldn't find that on my 25.24 Edge 840.

  • No, that stat doesn't show up anywhere on the Edge that I could see. It only appears on the activity stats in Garmin Connect. I just wait at least 2 minutes after pausing the activity on the Edge before saving it. It's a bit annoying that you don't get a visual countdown on the Edge but I just use the stopwatch on my phone.

  • I run my Fenix 7S Pro at the same time as my Edge 840 as a backup in case the Edge has issues with the activity. If all is well, I don't save the Fenix activity, just the Edge, although I'm wondering which one has the most complete set of data, the Fenix or the Edge (I'm a new Edge user, still learning how to use it)? It's a good thing that the Fenix shows the recovery heart rate count down timer. It's stupid that the Edge doesn't thought.
