Luxe won't track my heart rate accurately

[SunsetRunner]

I’ve spent years with a charge 2, upgraded tried both the charge 5 and Fitbit Luxe and same issue with both, the heart rate will NOT track about about 116 during running which I know **ahem** well mines above.. if fitbits new and improved algorithms are so wonderful why is it your earlier products can accurately track heart rate better than the new ones ? Multiple devices the same.

Makes me feel like my runs are nothing, my charge 2 is cracked so I needed a newer Fitbit and now I’m at a loss, I also tried the charge 3 when that came out and returned because it wasn’t even reading my heart rate.

Hi there, @SunsetRunner. Thanks for stopping by in the Community Forums and sharing the details about the inconvenience with your Luxe. 

Note that you might notice slight variations between your heart-rate reading on your new Fitbit devices compared with your old ones due to improvements in the heart rate sensor and algorithm.

Differences between heart-rate readings on your device and on exercise equipment are likely due to wrist or hand position. Make sure the back of your device is in contact with your wrist and that your band is snug.

Several factors can affect heart rate, including air temperature, stress level, alcohol or caffeine intake, immune response to illness, and medication use (source).

Exercising in cold weather can make it more difficult for your device to track your heart rate, as environmental conditions can affect skin perfusion (the amount of blood that flows through your skin). Spikes in your heart rate during sleep may be caused by sudden movements (for example, waking up and getting out of bed), or a weak signal due to wrist placement. 

As with all heart-rate tracking technology, accuracy is affected by personal physiology, device location on your arm, and type of movement. For a more accurate heart-rate 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.

To resolve common issues, see our troubleshooting steps in What factors can affect my heart-rate reading on my Fitbit device?

Hope this helps.

Hi,

im wearing it in the correct position, has the same issue with charge 5 and the luxe it’s about 25 beats difference so I wouldn’t say small difference. I’ll probably have to keep using the charge 2 for runs as it’s not giving an accurate read at all. 

are the heart rate zones higher with the newer devices or is that still the same like beats to be within zone categories ?

I bought the Sense 2 and it doesn’t read my heart rate accurately. My Sense 1 didn’t either and this is frustrating. I just did a more intense run and it shows 2 zone minutes with my heart rate reading resting the whole time. Google has not fixed anything on the sense. I ran about four miles and was dripping with sweat. There is no way my heart rate was resting!

I have been wearing the Charge series for years and they read my heart rate. I have Sense and all the one I have purchased have not read my HR accurately. I am wearing it correctly, have the sensors clean and reset it. This has been an ongoing issue with Sense series.
