There are known HR issues

[LokeAa]

I got this screenshot from a DEV forum. There are known HR issues with Sense, and it seems like they just don't care.

There are already several threads on this subject. 

The inaccuracy was introduced for some users with the latest firmware and it will take a firmware update to fix this. 

As customary with fitbit, users never feel updates are frequent enough. 

[LokeAa]

@Rich_Laue of course it isn't frequent enough when we have a device that is useless. If I had wanted a watch to show me the right time of the day, I had bought a watch not a Fitbit.

No update sense December 2020. It's rediculous. It reports my heart rate way below what it actually is and is extremely frustrating to see when I'm in the middle of a workout. Trying to adjust it to different parts of my wrist, wiping off sweat to see if it makes a difference, etc. I don't want to be fiddling with this thing when I'm dying on an exercise machine. My charge 2 had much better consistency. 

[Soltek]

just a thought but can we roll back the firmware update? and if so would this fix the issue? has anyone done this?

[LokeAa]

@Soltek Rollback isn't possible. You can set the device back to factory settings. When you reconnect, the latest firmware installs automatically.

Just bumping this up...yes, it's been reported many times, but if this forum weren't run by Fitbit, there would be a sticky on this.  It's a critical flaw, and for many (me included), as Loke said, it makes this product useless.  And Fitbit/Google's inability/unwillingness to fix it is tantamount to theft through deception.  

Worth noting as well, it's a problem that doesn't exist on some of their older hardware, e.g. my original Versa records HR accurately (or at least consistently and meaningfully).  

[Rich_Laue]

I don't see anything that says that fitbit isn't addressing this. Normally fitbit is fairly quiet on what they are working on, and with past problems we haven't seen any feedback and it the firmware updates are way to spaced out. 

Please remember that this forum is a Community Forum and like most other Community Forums, 99 % of the response are from the Users. The Fitbit Moderators really do not know much about development and are under NDA agreements. At best, posts can be past on, if they see them. 

[LokeAa]

@Rich_Laue , call me old fashioned, but when I buy a device, I want it to function when I buy it, not next year. 

[Rich_Laue]

I'm not saying that you don't, or that I don't. Simply saying that eventually this will be fixed. Fitbit seems to fix several issues at once, rather than an update per fix. 

However bumping may not get the desired response. 

Worth noting that the initial reviews before the latest firmware where very pod spruce with heart rate.

I wish I would have known about the issues with the Sense heart rate monitor before I bought it. I had a Charge 3 that I loved, and that helped me identify an issue with my heart rate which turned out to be me being in atrial fibrillation that required an atrial ablation. I bought the Sense to replace the Charge 3 because of the enhanced heart rate functions.  From the time I started using the Sense I had suspicions that there were issues with it. Initially my resting heart rate jumped 3 then 5 bpm over what it was with the Charge 3.  Then occasionally my exercise heart rate would go from a normal rate to 30+ bpm instantly. The latest situation that lead me to research the issue was when my heart rate was 140bpm while riding my zero turn radius mower.  Needless to say, I am no longer using the Sense and have went back to the Charge 3. Fitbit needs to get their heads out of the sand, admit there are issues with the Sense and fix it. 

[BITFITBART]

You're not however acknowledging the problem in your posts. 

Yes, they may be working on a solution and they may eventually implement a solution, the problem however is that this is a patently obvious flaw, it would have been discovered within three minutes of beta testing. Therefore we have to assume Fitbit/Google knew and chose to push out a fatally flawed product anyway and take our money for it.  After this decision, when people complained, they didn't acknowledge and offer accommodation, instead they (you assume) quietly have been working in the background to fix it...meaning perhaps, if you're right, and the solution is properly implemented, I may have a functioning device a half year or more after Fitbit/Google took my money. That's the problem.

@Rich_Laue The latest firmware release was in November, five months ago. Would you accept essential functionality not working on your phone for five months? Instead of acknowledging and reassure customers, what does Fitbit do? They start researching wrist-based blood pressure tracking in a month-long Sense study. 

[steveo57]

Yes that is what is bothering me too. Fix this and I will be happy. It affects all the calculations with amount of food to eat number of active zone minutes etc.  Spending money and time on blood pressure national studies and hiring national famous gurus to endorse wellness features but not solving this basic heart rate issue with the watch itself raises my blood pressure and affects my overall wellness🤑

[Rich_Laue]

I am simply a user, like you, I know as much about what fitbit is working on as you do. 

I simply was pointing out what my history with fitbit seems to be. 

@steveo57 as I pointed out, it can be frustrating. 

[steveo57]

@Rich_Laue  nothing I said was directed at you.  I see your comments in several threads and they are always positive and helpful.  I also try to help others with any knowledge I gain about solutions to problems with Fitbit but I am just frustrated with them not concentrating on the heartrate issue in a more expedient manner since it affects all other aspects of the watch. 

[Rich_Laue]

I was simply agreeing with your frustrations. 

[CathySeasoning]

Same. After the update last year, I thought something went wrong with the Ionic. So I thought maybe  a new fitbit will have a more accurate HR so I bought the Sense. So many issues in the get go. I dunno why I even try and give it a chance. I should have returned it. Smh. 

[Sharki9]

October 2021 it will be nearly a year since first Hr sense issue were reported and the problem is still not fixed, shame I only find out those forums when I suspected something wrong with readings, spoke to support - useless just waste of my time, first they were trying to say that there might be some difference in reading between devices then they admitted there is a problem saying that they only recently become aware of after me pointing them to the forum and posts from December 2020.

They do not want to replace or refund the device - great customer care ….

will have to see if I can return it via Amazon even though the seller was Fitbit.

having some Fitbit in the past I just didn’t  suspect that the most expensive Fitbit will be so sh…t , buying a device which knocking at the apple price brackets I expect it to work, not wait a year to admit there is a problem and maybe another year to fix it and by that time you will be thinking of replacing it with new watch anyway.
