Eight Sleep data, in your own stack.

Users connect their Eight Sleep account (Pod 3, 4 or 5) on your server's sign-in page. Open Health Sync pulls their nights on a schedule: sleep stages and score, heart rate, HRV, breathing rate, and bed and room temperature.

Know first

Before you start.

Eight Sleep has no public API or partner program. The connector signs in the way the Eight Sleep app does, so it can stop working when the app changes.
Eight Sleep's terms may not allow access by other software: read them before you turn it on, and tell your users what it does.
Your server keeps the password, sealed with your encryption key, so it can sign in again. It's never logged or returned.
It's on by default since it needs no keys of yours. Turn it off in the console.
