Yes! And add smart watch support for this! Currently it appears the smart watch can only track arm movements and heart rate but many watches also have a microphone. It would be nice if you could track arm movement, heart rate AND breathing 
Dear guys, it is not possible to use it with the accelerometer from miband II, isn’t it? Is this also planned?
Miband 2 is supported - you need to install either Tools & Miband or Notify & Fitness for Miband
I second this. A hybrid setup to use a watch to track heart rate and phone to do sonar and breathing detection would be great.

I love the idea of combining sonar and watch data! It might make overall data more accurate plus the addition of breath tracking would be awesome. Some watches like the new Ticwatch Pro have both a speaker and a microphone. Could the watch itself also act as a sonar sensor?
Well, this explains why my sleep data has stopped showing my breathing; I started using a Gear Fit 2. I mistakenly assumed that Sonar would continue to work on the phone while the Fit 2 handled Heart Rate data. That’s actually what’s implied in the UI; “Heart rate monitoring” is set to Samsung Gear while Sensor is set to Sonar. There’s no indication at all that Sonar will no longer work.
Please group these things more intuitively and make it clear that Sonar will be disabled if a Smart Watch/Tracker is used. Or better yet, allow us to use the Phone for Sonar and the Wearable for Heart Rate Tracking.
I’d really love to see the options presented as something like:
Sleep Tracking Sensors
Motion Tracking: [Sonar (Phone) | Accelerometer (Phone) | Accelerometer (Wearable)]
Heart Rate Tracking: [Bluetooth Smart | Wearable]
Breath Tracking: [Sonar (Phone) | Accelerometer (Wearable)]
I was excited to see that Sleep As Android supports the Fit 2 and that was actually the final bit of motivation that I needed to buy the thing. Now I am a sad panda! Guess I’ll just leave it on the charger overnight and go back to using Sonar and my Polar HR monitor.

Ouch! I can feel the frustration.
I also agree there should be a more intuitive setting for the sensors. There are invisible overrides - not only in wearables but you can for example set sleep tracking on Smartlight > Sleep Phaser and that one will also take precedence and not indicate that sonar/phone acc will not be used.
This is unfortunately a lot more work than it seems initially - we’ve spent ton of time already trying to figure out the most logical groupings and layouts of the settings but each one had different issues.
We’re definitely open to proposals.

Yea, I work with software engineers, so I’m aware of the difficulties and the can of worms that can be opened with even the most simple of changes. Fun fun! 
The biggest improvement for me right now would be that option to continue using Sonar on the phone instead of the accelerometer on the wearables while still using the heart rate sensor from the wearables.

I have a mi band 3 and use notify & fitness for mi band app. Would love to be able to use heart rate tracking from this, combined with sonar sleep tracking on my Samsung Galaxy S8

Hi, I would also like to know if it is possible to perform this type of monitoring: accelerometer and HR of the smartwatch + Sonar of the Smartphone.

This feature would be great to have. I’m looking to get light/breathing data while I’m also tracking HR on my watch.

So it sounds like there are a number of people who think this would be a great idea, including me. This feature request seems to have been out there for a long time. Is it known where this falls on the feature request priority list? Is it a big code rewrite or something? It seems like since both wearable heart rate tracking and sonar already exist that it wouldn’t be that large of an undertaking to implement having them coexist.
Just curious…

I would like to “upvote” this feature request. Sonar through the phone mic, heartrate through a wearable both running at the same time.

Another request for this. Like others, this is what I assumed it was doing when I enabled the Wear OS watch and the sonar…

I also would be interested to use both tracking systems at the same time.

Guess this just isn’t happening for some reason. I still don’t understand why, it’s a no-brainer and would be more beneficial to most people than so many of the features that are being added to Sleep as Android.
Everyone interested in this possibility please ensure you voted this feature up if you haven’t already so hopefully it gets more visibility.

How can we Up-Vote it. Yesterday I got the go2Sleep sensor and I am highly interested in the O2 and heart-rate measurement (until now I used a Polar H7 which is somehow not comfortable always). However, I realized that after activating the wearable (Thirdparty in this case), the Sonar and/or the accelerator of my smartphone is not working anymore.
As the extension of go2Sleep does not include movement tracking right now, I highly would like to have this feature activated on my smartphone as I am sure that the measurement with movement is more accurate than without. Its a bit unlucky because right now I do have movement tracking using sonar + heart rate tracking using Polar H7. Using the go2Sleep sensor, I could use the hear-rate sensor of this device which is much more comfortable + Oxygen measurement but then the movement tracking is not available.
Thank you in advance,
Tobi
PS: If I could support you here, just get in contact with me.

As many have indicated, the ability to use HR data from a non Bluetooth smart wearable (but one that is already integrated) in conjunction with sonar or the sleep phaser (my preference) would be fantastic. Maybe all it needs is a checkbox/switch to ignore accelerometer data from the watch?

Honorary Vote since I’ve already used up my 5 vote limit (Why can’t we have more votes? 
). The more accuracy the better, especially if one set of readings is suspected as an error, the other readings can help confirm or deny that.
Though the user may need a fast-charger for their phones if they seem not to keep up with charging. Luckily I got one since before when my phone used to go dead despite being plugged in. It’s all good now.
