Versa 4 heart rate not working

[Lebken]

I’ve owned several Fitbit watches. Why can’t the heart monitor work. 
I match it to an arm band Wahoo and  it’s not even close, especially in upper level heart rates. How can you expect the cardio load program to work. Garbage in, garbage out.

Hi there, @Lebken. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention. I'm sorry to hear that the heart rate monitor is not working properly on your Versa 4. I understand your concern, I will do my best to help you with this!

If you haven't done so yet, I'd recommend taking a look at this help article What factors can affect my heart-rate reading on my Fitbit device?

I have the same issue with my new versa four. And I’ve seen several people saying the same thing on Facebook. It’s frustrating because we’re not getting any cardio load all of a sudden

The cardio load seems like a great tool but when I’m riding my stationary, for example, I can run a program which keeps my resistance and my heart rate very locked in. My Wahoo arm band is consistent at say 140 bpm and the Versa 4 is everywhere from 140 to 114, and sometimes nothing at all indicated. What the difference between the Wahoo and the Fitbit? They use the same technology. 🤷🏻‍:male_sign:

I had my Versa 4 since March last year and the HR monitor was fine, then all of a sudden it stopped working properly, recording any walking I did at up and over 140bpm. I walk fairly leisurely so there's no way that's correct. I spent 5 months trying to convince support via X that my device was not working, possibly due to an update which corrupted the HR (that' the only explanation). I finally got a new Versa, updated it and the same thing is happening. I do a short walk, no more than 20 mins, check what's been recorded in the app and my HR has been up to 160bpm. I don't even reach that when I'm doing HIIT exs. It's very frustrating, you cannot track your fitness or wellness when that happens!

I’ve tried several things to get my Versa 4 to keep a more accurate heart rate. Tightening it while I on the stationary bike seems to help some but if I move my arm wrong I lose signal
or something and just get dashes until it returns. Regardless, I don’t understand why a mediocre arm band can keep perfect track and the Versa with the same technology struggles to keep up.
