Heart rate data in Active Zone Minutes graph

[Shakey-Shane]

So, I’m not sure if it’s me being dumb or if it’s something not right with the way the new activity zone minutes (AZM) system calculates it’s information

One days readings with only the duration of the day changing (screen prints to prove the changes)

00:00 to 07:30 (T1) nothing out of the ordinary

00:00 to 12:00 (T2) I’ve taken a small walk to drop my daughter of at school, then taken a trip down two. About an hours walking
00:00 to 18:00 (T3) I’ve walked back home, picked my daughter up from school and been on a vigorous 30 minutes run which got my heart pumping

I can see that my heart rate (HR) was 51bpm at (1am BPM) when I was asleep (T1). Looking at (1am BPM), time duration (T2) this now shows 98 BPM.
During T1, T2 and T3 my (HR) for the (AZM) for (1am BMP) increased from 51bpm to 98 bpm to a whopping 178bpm.

How is this correct as the (T1’s) previous data is now historical. I’ve looked at every day since the new (AZM) and they are all the same. Around 1am in the morning, it increases the HR without any activity taking place matching that of any vigorous workout I have undertaken for that day.

is it just my watch or is everyone’s doing the same. The chart I’m on about can be found on the (AZM) section and swiping to the left

@Shakey-Shane It's nice to see you in the Fitbit Community. Thanks for getting in touch about this. 

I appreciate the detailed information shared and for letting me know that this information could be found in the Active Zone Minutes graph.

Based in the information you have provided, I believe this could be related to the heart rate data you're receiving for this please follow these tips to improve the accuracy of your heart reading: 

• Wear your Fitbit device on top of your wrist, and make sure the back of the device is in contact with your skin.
• When you’re not exercising, wear your device a finger’s width above your wrist bone.
• During exercise, wear your device a bit tighter and higher for an improved fit. The band should be snug but not constricting (a tight band restricts blood flow, potentially affecting the heart-rate signal). Many exercises such as bike riding or weight lifting cause you to bend your wrist frequently, which could interfere with the heart-rate signal if the watch is lower on your wrist.

Also you may want to check the factors that can affect your heart-rate reading on your Fitbit device. 

I'll be around if you have any additional questions.

I am experiencing this same problem. I noticed heart rate spikes seemed to be popping after exercising for times hours earlier in the day. So I took a screenshot of the azm graph in the morning, then later in the afternoon when I looked at it, sure enough, there was a spike in heart rate added to the graph for a time when I was sleeping. it makes no sense.

Thanks for the reply moderator @SilviaFitbit, but I’ve given up on FitBits programmers as they seem to be on to a world of to their own by only doing things half hearted and never completing things fully before they start another half hearted project. Whilst my Ionic still works, I’ll keep using it, but when it fails, I’ll be switching brands as I’ve as much loyalty to the brand as they have to their end users 

@MelissaCamille, I’d give up on it as you can see they feel it’s an end users fault whereas it only happened on mine when they launched that section of software. 

this list of rubbish is quite exceptional regarding the list of things that FitBit don’t seem to acknowledge. I think the only people who complain about these products and features on the ones who uses them to track their activities fully whereas most obviously don’t hence why they don’t notice them

[MelissaCamille]

Yes, I’ve been very disappointed by the response by support. I’ve spoken to them twice and they act like I’m the only user who has mentioned this problem. If they don’t rectify it, my only course of action is to leave negative reviews of their product. As you said, most casual users will not likely notice a glitch like this, but is IS consistent. Every time I exercise and earn active zone minutes, a spike in heart rate is added to a time when I was sleeping the night before. If I don’t earn any active zone minutes, no random spike shows up. It’s something they need to fix on their end.
