Luxe won't track my SpO2 data

[rpayne88]

I just bought a luxe yesterday and wore it to bed.  Despite having the latest firmware and the SpO2 app installed, it still reads "--".

I bought this mainly to have an SpO2 readout while flying (most small planes are unpressurized,) but this thing refuses to read even while I'm asleep.

How do I get this thing to actually work?

Hi there, @rpayne88. Welcome to the Community Forums. Thanks for the details provided in your post about the issue with your Luxe. I understand where your concern is coming from. 

Since you're seeing only dashed lines on the clock face or SpO2 tile, a message that the SpO2 data couldn’t be read, or missing data in the Health Metrics tile in the Fitbit app on your phone, keep in mind the following:

• Your device doesn’t retroactively measure your SpO2 values. When you start using Fitbit SpO2, you’ll see dashed lines until after your next sleep session.
• You must get at least 3 hours of quality sleep. Data is only collected when you’re still. If you move a lot during your sleep or the sleep session is too short, you might not get SpO2 data.
• Charge your Fitbit device to make sure it’s able to collect data throughout your entire sleep session. Note that you may have to charge your Fitbit device more often when using an SpO2 clock face or app.
• You must sync your Fitbit device with the Fitbit app before the clock shows your SpO2 data. Note that it may take around an hour for your SpO2 values to appear after you sync your device. For troubleshooting syncing, see Why won't my Fitbit device sync?
• Turning off any SpO2 clock face or app permissions can cause the feature to stop functioning. For instructions on adjusting permissions, see How do I install and manage apps on my Fitbit device?
• Your Fitbit device must be able to consistently track your SpO2 data:
  • Wear your device slightly higher on your wrist.
  • Make sure your device is in contact with your skin.
  • Your device should be snug but not constricting.
  • Tattooed skin can impact the accuracy of the red and infrared sensors on your Fitbit device.

Hope that helps.
