If your Fitbit Inspire 2 is not tracking your sleep, you are not alone. This is a common issue that many users have faced. The Inspire 2 is designed to record sleep data automatically, but sometimes it fails to do so. There are several troubleshooting steps you can take to try and resolve the issue. Firstly, check that the On Wrist mode is switched on, as the tracker does not monitor heart rate or track sleep when in On Clip mode. Additionally, ensure that your device has sufficient battery life, as the sleep function will turn off automatically if the battery is critically low. You can also try restarting your device, updating the software, or performing a factory reset. If these steps do not work, you may need to contact Fitbit's customer support team for further assistance.

What You'll Learn

The Inspire 2 might not be tracking sleep due to a low battery
If your Inspire 2 is not tracking your sleep, it might be because of a low battery. The Inspire 2 has a battery life of up to 10 days, which is double that of its predecessors. However, this extended battery life might give you a false sense of security, leading you to forget to charge your device. If the battery is critically low, the Inspire 2 will automatically turn off the sleep function to conserve power. Therefore, it is important to ensure that your device is sufficiently charged before using it to track your sleep.
To troubleshoot this issue, the first step is to check the battery level of your Inspire 2 and charge it if necessary. It is recommended to have a battery level above 60% before using the sleep tracking function. If the battery is low, connect the device to its charger and allow it to charge fully before attempting to use the sleep tracking feature again.
If your Inspire 2 still fails to track your sleep after ensuring it is sufficiently charged, there are a few other steps you can take. Firstly, make sure that the "`On Wrist` mode is activated". The Inspire 2 can be worn on the wrist or as a clip, and sleep tracking is only available when the device is in "On Wrist" mode. To check this setting, open the main clock face, scroll up to Settings, select it, and then scroll to find the clip option.
Another general troubleshooting tip for Fitbit devices is to restart them. This can often resolve minor software issues that may be causing problems with sleep tracking. To restart your Inspire 2, go to the Settings app, scroll down to "About," and tap "Restart Device." Additionally, you can try updating your device to the latest software version, as outdated software may cause issues with sleep tracking. To check for updates, go to the Settings app, scroll down to "About," and tap "Update Device."
If none of these steps resolve the issue, you may need to contact Fitbit customer support for further assistance. They can provide troubleshooting guidance specific to your device, and your Inspire 2 may still be under warranty if it is a recent purchase.

The device is not on the user's wrist
If your Fitbit Inspire 2 is not tracking your sleep, it could be because you are not wearing the device on your wrist. The Inspire 2 can be worn on the wrist or as a clip. If the "On Clip" mode is active, the tracker does not monitor heart rate and other features, including sleep tracking. To check this, open the main clock face and scroll up to Settings. Choose that and scroll up or down to find the clip option.
If the "On Wrist" mode is switched on, the issue could be related to the placement of the device on your wrist. The band being the wrong tension means it might not be making consistent contact with your arm. Fitbit suggests wearing it a bit higher than you would during the day (2-3 finger widths above your wrist bone) for ideal results. It should be snug against your wrist but not too tight.
If you are wearing the Inspire 2 on your wrist with the correct settings and placement, and it is still not tracking your sleep, there are a few other things you can try. Firstly, check that the device is charged. If the battery is critically low, the wearable will turn off the sleep function automatically. You can also try restarting your device, which can resolve minor software issues. To restart your Fitbit Inspire 2, go to the Settings app, scroll down to About, and tap Restart Device. Finally, make sure that sleep tracking is turned on. In the Fitbit app on your phone, go to Account > Inspire 2 > Sleep > Sleep Tracking, and ensure that it is activated.

The heart rate sensor is dirty or damaged
If your Fitbit Inspire 2 is not tracking your sleep, it could be because the heart rate sensor is dirty or clogged with sweat, which can interfere with its accuracy. The heart rate sensor needs to be in close contact with your skin to get an accurate reading.
To clean the sensor, use a soft, damp cloth to gently wipe the sensor on the back of your Fitbit. Make sure the sensor is dry before putting it back on. You should clean your Fitbit regularly to remove any dirt or sweat that could interfere with the heart rate sensor.
If cleaning the sensor does not resolve the issue, try the following steps:
- Restart your Fitbit: Go to the Settings app, scroll down to About, and tap Restart Device.
- Update your Fitbit: If your Fitbit is not running the latest software, it may have issues with sleep tracking. To check for updates, go to the Settings app, scroll down to About, and tap Update Device.
- Check the "On Wrist" mode is switched on: Inspire 2 can be worn on the wrist or as a clip. If the "On Clip" mode is active, the tracker does not monitor heart rate and some other features, including sleep tracking. To find this, open the main clock face and scroll up to Settings. Choose that and scroll up or down to find the clip option.
- Check the battery: If the battery is critically low, the wearable will turn off the sleep function automatically. Make sure your battery is topped up.
- Contact Fitbit's customer support team: If none of the above steps resolve the issue, Fitbit's customer support team can provide further assistance and troubleshooting specific to your device.

The sleep tracking setting is not enabled
If your Fitbit Inspire 2 is not tracking your sleep, there could be a few reasons why. Firstly, it is important to ensure that the “On Wrist” mode is switched on. Inspire 2 can be worn on the wrist or as a clip, and if the “On Clip” mode is active, the tracker will not monitor heart rate or sleep data. To check this setting, open the main clock face and scroll up to Settings. Choose that and scroll up or down to find the clip option.
Another reason could be that the sleep tracking setting is not enabled. To check this, go to the Fitbit app on your phone, and then go to Account > Inspire 2 > Sleep > Sleep Tracking, and make sure it's turned on.
If you are still experiencing issues, try restarting your Fitbit. This can be done by going to the Settings app, scrolling down to About, and tapping Restart Device.
If none of these steps resolve the issue, you may need to contact Fitbit support for further assistance.

The device is not set to sensitive or normal in the sleep section
If your Inspire 2 is not tracking your sleep, it could be that the device is not set to "Sensitive" or "Normal" in the sleep section. The "Normal" setting is the default option and counts significant movements, such as rolling over, as time spent awake. On the other hand, the "Sensitive" setting records nearly all movements as time spent restless or awake. This setting may be helpful if you wake up feeling tired even though your sleep history shows sufficient rest.
To check or change your sleep sensitivity setting, open the Fitbit app on your phone and follow these steps: From the “Today” tab, tap your profile picture, then “Fitbit settings”. In the “Preferences section”, tap “Sleep”. In the “Feature settings” section, tap “Sleep sensitivity” and make your desired changes.
If your Inspire 2 is still not tracking your sleep after checking the sleep sensitivity settings, there are several other potential solutions you can try. Firstly, ensure that your Fitbit is set to "Wrist mode" and not "Clip mode", as the latter turns off the heart rate sensors and can affect sleep tracking. Additionally, make sure that your Fitbit is snugly and securely attached to your wrist, as a loose fit can also impact sleep tracking. Another solution is to restart your Fitbit, which can resolve minor software issues. You can do this by going to the Settings app, scrolling down to "About", and tapping "Restart Device".
If none of these solutions work, you may need to try more advanced troubleshooting methods, such as factory resetting your Fitbit Inspire 2 or contacting Fitbit customer support for further assistance.
