Hello,
May I please make the request to support the Fitbit Charge 6? The Fitbit Charge 6 does support 3rd party apps and has both spO2 and HR Sensors. This would be perfect for Sleep As Android to be able to sync with.
I love the Sleep As Android app and wish that you could expand the range of Fitbit devices that you support.
Thank-you.

Hello @Christopher_B many thanks, I’m waiting for my collegue @jiri-urbandroid to hand me over some store details and we will look into this..
Hey, just wondering if you have any more information on whether support for this device can be expected?
Hi @rskuipers, sadly, this does not depend on us… For any integration, we need an open API. And FitBit only provides API for a few models. The Charge line has never had public-facing API, so I am afraid they do not plan to open the platform. I really wish I had a better reply, we can only hope Google will reconsider.
Thanks for the quick reply. I still went and bought it but here’s to hoping that google decides to improve it and open it up somehow.
You can combine the phone’s sensors and HR from the wearable - in that case, configure:
Settings → Sleep tracking → Wearables → Wearable → NONE
Settings → Sleep tracking → Wearables → Smart Bluetooth→ enabled
Our chances Google will change the decision are not very high, but we still hope 
Hi @petr-urbandroid / @lenka-urbandroid / all,
Just wondering: if Fitbit Charge 6 heart rate can be shared with gym equipment, wouldnt it be possible to have it shared with Sleep as Android as well? Wouldnt it be the same API?

Hi @HoneyBadger, do you get HR data, if you enable Settings > Sleep tracking > Wearables > Bluetooth smart?
We use GATT Heart Rate Profile, which is supported by the majority of wearables, even if the wearable itself if not compatible.
Hello, I’m just wondering if there’s any more on this, I’m a long time Sleep premium user and just got a Fitbit, someone else posted a video about API above, can we integrate yet?
HI @Sam_D, the video for the FitBit charge only talks about real-time HR data, which is already possible via Smart Bluetooth¨option. The movement data are not available in the real time, but you can combine the HR from the wearable with the movement data from the phone’s sensors (accelerometer or sonar).
Thanks Lenka, that’s great and I’ll look into it but is there an upcoming option to just integrate the Charge 6 with Sleep as a whole?
I hope the Fitbit Charge 6 will be add, it’s a high tier sensor’s fit wear !
Hi @Nicolas_Delfino, FitBit Charge models do not have an open API with direct access to the sensor in real time. Unless FitBit publishes an open-facing API, the wearable can be used only for collecting HR data via Smart Bluetooth.
Does this change anything?
Hi @Unspec7, we went ahead and applied for verification.
However, we do have some reservations about the project’s longevity, to be completely honest. Google’s frequent shifts (from Google Health to Fit and back again) have previously forced us to a total API rewrite.
We want to be sure this iteration is here to stay before we heavily invest our time.
Syncing data is already possible via Health Connect, so we are looking into whether that provides a more stable, long-term path for us.
We will definitely check it out, though!
Thanks! Also, kind of related, but it looks like Sleep’s smart bluetooth feature for HR tracking and such doesn’t work with the new Fitbit Air.
Is FitBit Air using the standard GATT Heart Rate Profile?
If you enable Smart Bluetooth in the Sleep app, you should see a list of nearby BT devices. Is FitBit listed with a heart icon or the BT icon?
Just wanted to say that the Fitbit Air does not show a heart icon, just the BT icon.
If the heart rate icon does not show there, the watch is using another protocol for HR data. Are there settings in the watch that allow you to change it to the GATT Heart Rate Profile?
Alternatively, you can let Health Connect or S Health sync the HR to Sleep.
