Set up the Withings Sleep Analyzer beneath your mattress, connect it to power and Wi-Fi in the Withings app, and let calibration finish before using it. The main settings to understand are user-recognition sensitivity, the sound sensor for snoring and breathing-disturbance tracking, and the separate sleep-apnea detection mode. Availability and behavior depend on the feature and region.
Where should I place the Sleep Analyzer?
Install the sensor entirely beneath the mattress, or between the mattress and a topper or pad. Withings recommends positioning it around chest or heart level. Use the supplied power adapter; the device is designed to track one person, so placement and the assigned user matter.
In the Withings app, open Devices, tap Add, choose Sleep sensors, select Sleep or Sleep Analyzer, and tap Install. Follow the prompts to connect the sensor to your Wi-Fi network. Leave the bed unoccupied while it calibrates: Withings says calibration may take up to 10 minutes. See Withings’ installation instructions.
After initial setup, your phone does not need to stay beside you overnight. The sensor sends results over Wi-Fi. The 2023 product guide lists iOS 14.0 or later and Android 8.0 or later as installation requirements; these are guide-era requirements, so check current app compatibility before installing. The guide also says the phone needs Wi-Fi and internet access to synchronize results. Read the Sleep Analyzer Product Guide (version 6.0, 2023).

How do I change Sleep Analyzer settings in the app?
Settings are managed from the device entry in the Withings app. The relevant paths below use the labels in Withings’ support instructions; labels may vary with app version or region.
Adjust user-recognition sensitivity
If the app does not recognize that the assigned person is in bed, open Devices > Sleep Analyzer > Settings and look for the sensitivity option. It affects recognition of the user, not the sleep results themselves. Withings presents this as a troubleshooting adjustment for someone who sleeps alone and advises against increasing sensitivity unless Support requests it. If recognition remains unreliable, contact Withings Support rather than treating the option as a way to change measurement quality. See Withings’ sensitivity guidance and device-use guidance.

Turn the sound sensor on or off
Withings uses sound analysis along with respiratory patterns to help distinguish the tracked user’s snoring from a partner’s. The company says the Sleep Analyzer does not store audio recordings; it records whether snoring occurred. To change the setting, go to Devices > Sleep Analyzer > More settings > Sound sensor. Withings says devices running firmware 1871 or later require snoring detection to be enabled to receive breathing-disturbance data. See Withings’ snoring-tracking instructions.
Enable sleep-apnea detection
Withings’ activation path is Devices > Sleep Analyzer > Activate sleep apnea. The feature is geographically limited: the installation instructions describe it as available to EU users, while the product guide describes the Sleep Apnea Detector as available in non-US regions. Those descriptions do not establish availability in every country outside the United States. Check whether the option appears in your current app and consult Withings’ local availability information before relying on it. See Withings’ activation instructions.

Why can’t I enable apnea detection and breathing disturbances together?
They are alternative modes, not simultaneous measurements. Enabling Sleep Apnea Detector disables breathing-disturbance detection and replaces the breathing-disturbance data accumulated previously. If you switch modes, do not expect both sets of data to continue updating together.
| Mode | What it provides | Availability and trade-off |
|---|---|---|
| Breathing-disturbance tracking | Breathing-disturbance data; Withings says snoring detection must be enabled on firmware 1871 and later. | Availability is not stated consistently for every region in the cited support pages. Enabling apnea detection turns this mode off and replaces its accumulated data. |
| Sleep Apnea Detector | A separate feature Withings describes in its product guide as medical software. | Withings’ installation page limits activation to EU users, while the guide describes availability in non-US regions. Check the current app for local eligibility. It cannot run alongside breathing-disturbance tracking. |
For the documented mode behavior, consult the activation instructions and the 2023 product guide.

When do results appear, and what does the app show?
Sleep data normally appears in the app shortly after you get out of bed. A weak Wi-Fi connection can delay synchronization by a few hours. The Home tab shows results and historical data. Withings lists sleep duration, light, deep and REM stages, interruptions, time to fall asleep, heart rate, and snoring among the measurements. These are manufacturer-documented outputs, not a guarantee that every measure will be available in every mode or circumstance.
Withings says its sleep-stage algorithm uses heart rate, respiration rate, and movement, and that it was calibrated at Paris-Béclère Hospital against clinical recordings, including polysomnography. That is the company’s description; the cited materials do not independently establish the algorithm’s accuracy or clinical performance. For synchronization and measurement details, see Withings’ sleep-tracking support page.

Is Sleep Analyzer the same device as Withings Sleep?
No. Withings identifies Sleep and Sleep Analyzer as different devices, even though the installation flow may present both names under Sleep sensors. Do not assume their features are interchangeable: Withings assigns sleep-apnea detection to Sleep Analyzer. Confirm the model name in the app before following model-specific settings instructions. See the installation guide.
What are the safety and mattress limitations?
Sleep tracking and apnea-related outputs should not be treated as a diagnosis. Withings says Sleep Apnea Detector interpretations are potential findings, not a complete diagnosis, and advises consulting a qualified health professional before acting on results. Do not change medication or treatment based on app data without a doctor’s advice.
- The 2023 product guide says not to use the device with waterbeds, air beds, or mechanically articulated mattresses.
- It says Sleep Apnea Detector is not indicated for people with arrhythmia, cardiac insufficiency, asthma, or COPD.
- Ask a qualified clinician how to interpret a concerning result; do not use the feature as a substitute for medical evaluation.
