Health app: heart rate not always showing in GadgetBridge

[nietsmmar]

When I download my CSV it gives me my heartrate data, although min and max values are always the same. Shouldn't they differ as the logs are a summary over ten minutes? Is there some setting I am missing?

Also the logs are not always showing in my GadgetBridge. For example it does not show any heart activity the whole night that I've slept and even some hours before that. While later it shows my heart data again. But all these hours are in the CSV file.

So you downloaded the 'Health' data as a CSV file? What firmware version is your watch on? Is it definitely on the latest (2v27?) and all your apps are up to date?

Min/max was added in 2v26, so it'd start recording after that but ONLY if the health data for that month was in the new format. So if you updated sometime this month it won't have stored the data for this (or previous) months. It'd start next month though.

Also the logs are not always showing in my GadgetBridge.

If you press the settings gear icon in the device card in gadgetbridge, then scroll down and tap 'Full Sync' (and wait a while) it should sync up. Possibly battery/memory saving for Gadgetbridge in Android hasn't been entirely disabled and the phone is shutting Gadgetbridge overnight and causing sync issues?

I realized that this does also apply to steps count.

Hi - you say:

until I wake up and connect my bangle in the gadgetbridge

Do you deliberately disconnect your Bangle at night then? Ideally Gadgetbridge should be set to automatically reconnect so unless you explicitly disconnect it you shouldn't have to reconnect (https://www.espruino.com/Gadgetbridge#extra-setup)

Just checking in case it's a timezone issue with syncing - what timezone are you in?

[nietsmmar]

Hey :)
I deliberately disconnect to save power on my watch. But not only at nights. I have it disconnected most of the times. But it resyncs my data over the day. Just stops at doing this from new daystart until I connect it one time. Then it only syncs data measured from that time and not from before since daystart.

I am in CEST timezone. (Germany)

Ok, thanks. That would have been handy to know originally! So if you don't actually disconnect it, everything works?

I just figured out what the issue is - something on the Bangle that retrieved the data wasn't pulling the latest day, but only if you gave it a time that was later than the current time (which always happened as it was asking for data from yesterday evening, in the morning). If you install health 0.33 it should now be fixed going forward.

The "full sync" should still fix all past data, but it does take a long time - maybe 10 seconds per day you've had it - and if you change app in the middle of it, it'll stop.

Have you actually tried to see how much worse it is if you just stay connected? Because if it's connected but not transferring data the Bangle goes into a power save mode so shouldn't really use any more power than if it was disconnected. It'd definitely save you a bunch of trouble disconnecting/reconnecting every day.

The new Gadgetbridge's have an option to not forward notifications if DND is on in the phone, so the only thing taking slightly more power than normal would be reporting the health data every 10 minutes (which won't be huge).

[nietsmmar]

Thanks! That is awesome!

Do you mean the full sync should work without the update already? Because it doesn't. I tried this every day. But the gaps are still there. Or did I understand wrong and this also only works after health update to 0.33?

Have you actually tried to see how much worse it is if you just stay connected?

I did not try. I only have the bangle for a few days now and I just naively assumed that it would safe power to not have it connected all the time.

[nietsmmar]

I updated the health app. full sync does not fill the gaps. But it also takes only a split second to do the full sync although the modal says it will take long like you said.

[gfwilliams]

Ok, thanks. Full Sync should have worked on the old health too - it would be really handy to have a debug log from Gadgetbridge when you do a full sync (https://gadgetbridge.org/internals/topics/logs/) and it might show what's gone wrong - maybe email it to me personally at gw@pur3.co.uk to avoid having to worry about any personal info in there?

[gfwilliams]

Thanks for the email! I just tracked this down - again, another issue in the Health app! If you install 0.34 from the 'development' app loader then it should be fixed and you can do a full sync (which will take a while this time!).

It wasn't uploading the first-stored month of data (which in your case was everything until today, when Full Sync took a little longer because it was filling in the data so far today)
