Celeste+ App Setup Guide — provided by EnsoData
Getting Started
Follow these steps before your first night of testing.
Charge Your Device & Prepare Your Phone
Charge your sleep device to at least 60% before your first night. Make sure your phone has at least 350 MB of free storage. Plug your phone in before bed -- the recording will not complete if your phone shuts down during the night.
- Android 12+ or iPhone iOS 15.2+ required
- Keep your phone within 15 feet of your head while sleeping
- Plug your phone in -- do not let it die overnight
Download the Celeste+ App
Download Celeste+ from the App Store (iPhone) or Google Play Store (Android). The first time you open it, read and accept the terms and conditions, then allow Bluetooth connections when prompted.
- Search "Celeste+" in your app store
- Allow Bluetooth when the app asks for permission
- Update the app if prompted before using it
Enter Your Setup Code & Connect the Device
Enter the setup code your clinic sent you to link your sleep test. Enter your personal information when prompted and tap Finish. Then tap Scan, select your device from the list, and tap Connect.
- Your setup code was in the email or SMS from your clinic
- Double-check your personal information for accuracy
- The app stores your device automatically for future nights
Tap "Record Now" When Ready for Bed
Once the wrist band is on and the finger sensor is clipped, tap "Record Now" in the app. The recording timecard turns green when you have recorded the minimum required time. In the morning, tap "End Recording" and keep the app open until your study finishes sending.
- Do not force-close the app while recording
- Keep the app open after tapping End Recording until upload completes
- Tap "Back to Home" to see your recorded nights and start the next night
How to Wear Your Device
The device wears on your wrist like a watch, with a sensor that clips to a finger.
Wear the Band on Your Wrist
The main device wraps around your wrist like a watch. Fasten it snugly so it stays in place during sleep but is not uncomfortably tight.
Clip the Sensor to a Finger
A sensor extends from the wrist band and clips onto a finger -- index, middle, or ring finger work best. The pinky is usually too slim for a secure fit. The sensor should feel snug and not slide around.
Check the App for Good Signal
After putting the device on, check the Celeste+ app -- it will show your signal quality. The device sensor light is red, which is normal. Confirmation that it's reading correctly comes from the app showing a good signal.
Keep It On All Night
Keep the device on from when you go to bed until you wake up. It's fine if you get up briefly during the night -- just keep it on your finger.
Quick Reference
Wear band on wrist; clip sensor to index, middle, or ring finger
Check the app shows good signal before sleeping
Use the pinky finger -- it is usually too loose
