Estimated oxygen variation not working

[MadamQ]

I have the box, but nothing has ever been inside it.

For it to show information you have to be using a Charge 3, Ionic or Versa. See: Help article: How do I track my estimated oxygen variation in the Fitbit app?

I still do not have the estimated oxygen graph showing. Been one week since I last had the information. Cleaned the back of the Charge 3 also. The sleep graph works just fine.

[LaGeezie]

Same here. The box is there but no data. Shows my sleep info but not this. 

[Dottie1951]

It's been since March 18th and still no EOV information. I can only assume this is an ongoing problem. Yes every thing the article said to do has been done to my Charge 3, still not working. I see this is something not being taking to task. Was nice when it worked but to just stop without any answer why!

[TriciaJul]

Same thing happened to me.  Everything else working/displaying fine..  this annoys me because I also pay for premium.

Hello @TriciaJul and welcome to the Help forums.  This thread got hijacked by some Charge 3 users, but it is in the Inspire/Inspire HR forum.  You don't say what tracker you are using and that makes a big difference.  The Inspire HR doesn't have the hardware to give an EOV graph.

What tracker do you use?  The EOV graph is on Ionic/Versa family/Charge 3.  The EOV isn't a premium feature and is available to all users with the right hardware. 

[TriciaJul]

Oh gosh...I am sorry..  it is a Charge 3!

[Dottie1951]

Charge 3. FYI the EOV started working again on April 4th.

[TriciaJul]

Thanks...it has not started working again for me as of 4/15

 The EOV doesn’t work on my Charge 3.  Box is there but no data.  Has not worked since I bought it

I have ionic. No box, no EOV. All my sleep data is there.

I use Charge 2 - I have a box for the report, but never had a report.

[SteveH]

@kavr it doesn't work with the Charge 2

[SunsetRunner]

Has anybody got a true solution from Fitbit ?  Saying to be sure you are using a Charge 3 is not a good answer.  For me, the estimated oxygen variation worked well from February to the 30th of April. Now it's blank.  I also noticed the red led is no longer lid at night as it was just before.

[SteveH]

@SunsetRunner it may not have answered your question but it did explain why the person with an Inspire was having issues. Other questions should be asked in a separate thread rather than hijack this one.

[SunsetRunner]

Sorry to offend you.  I though this was a forum and other people also stated having the same problem with there Charge 3. Just wanted to know the solution.

By the way, my Charge 3 's red led started working at midnight.  I found the reason.

Have a nice day.

[SunsetRunner]

SteveH you are stating the obvious,  we all can read.  Thanks...

Hi all, I have the Charge 4. I have the EOV box on the app but zero data on oxygen. I’ll keep looking on the forum for info related to Charge 4 but this is where the site initially directed me. 

also, I’ve followed the steps previously mentioned - charged the Fitbit, cleaned off back of it where the sensors are. And I don’t move much when I sleep (sometimes wake up in same position 😳)

Estimated oxygen variation seen since 11 May. Why can't we get a straight answer????
