I am very interested to hear this though. While I am not a sleep wellness professional, I am obsessed with tracking my sleep.
My favorite thing is the SleepAsAndroid App with all the integrations. I have used the following to track my sleep with it:
- Accelerometer Sensor
- Sonar Sensor
- Multiple Fitness Bands (multiple Xiaomi Mi Bands, Huami Amazfit Band)
- Smart Ring (Go2Sleep)
- Samsung Galaxy Watch
- Sleep Phaser
- Wear OS Watch (Ticwatch Pro 5)
Tracking:
- Breath Rate monitoring
- SpO2 / Blood oxygen monitoring
- Movement intensity
- Heart Rate monitoring
- Heart Rate Variability (HRV)
- Light Detection
- Sound Recognition (including snoring instances/rate and sleep talk recording)
- Sleep cycles (light, deep, REM phases) and Chronotype detection.
- Tag tracking: Location, sick, rain, snow, thunder, medication, drinking, phase of the moon, literally anything you want to see how it affects your sleep on the days it exists and doesn’t.
- etc.
Smart wake up times (so it wakes me up at the right time so I don’t feel tired), and ways to ensure I can’t sleep through my alarm, among many other cool features, many of which I don’t use.
The STATISTICS from this thing are incredible. It even has the option for an AI sleep assistant to summarize the sleep quality, trends, advice, etc.
In fact, my VERY FIRST post in this Wyze forum was begging for Wyze to add Sleep support:
I also use a Google Hub to separately track my sleep.
So…I may not be a sleep wellness “professional” but I am demonstrably pretty obsessed with my sleep, so hopefully Wyze considers letting me eventually beta test whatever they’re up to here! 
I’ll probably buy/implement it anyway 
Whatever you do Wyze, please consider allowing Sleep As Android access to integrate the data this time. There are a number of people who specifically check what is accessible by or integrated with SAS before they will buy things related to sleep.
