Welcome to the Community @Catwell. If your heart rate sensor is not working, I recommend restarting your tracker and check your heart rate settings by doing the following from a computer:
1. Go to Settings
2. Go to Blaze
3. Go to heart rate
4. Check if you've it on "On" or "Auto"
5. Save
6. Sync
I also recommend keeping clean the heart rate sensor to have a better reading of it.
Let me know the outcome. ![]()
