Fix #4: Ensure to place the Fitbit Versa 4 properly on your wrist.

When the Fitbit heart rate monitor’s sensors don’t make enough contact with your skin, the device may not work or provide accurate data. Your Fitbit Versa 4 should be worn a finger’s width above your wrist bone, on top of your wrist. This is vital since Fitbit tracks your heart rate with the help of a sensor that emits green lights. The green light detects the volume changes in the capillaries just above your wrist and your Fitbit then will determine your heart rate based on the data from the sensors.

Fix #5: Use the right bands for your Fitbit Versa 4.

There are certain accessory bands from third-party sellers that are loose on the wrist when worn. As mentioned above, it is important for the sensors at the back of the watch to make contact with your skin for the Fitbit heart rate tracking. If you’re not using Fitbit’s standard bands, be certain to tighten the band on your wrist to get accurate reading for your heart rate.

Fix #6: Try changing your clock face.

Several customers have reported that switching out the Fitbit Versa 4’s clock face helped rectify the issue with the heart rate readings on their devices. If you haven’t done this yet and the problem still persists, here’s how:

  1. I had to do all these steps and it didn’t work until I deleted and reloaded the fitbit app on my phone, then the pulse monitor and a few other items started working. Of course I lost all my data history but it is better than buying a new watch.
