If the EEG signal quality wasn't good enough, you will see a message, in the "HOME" section of the app, indicating that your sleep cards could not be generated.
Several reasons may explain a bad signal quality:
- A bad position of the headband on your head. To make sure you are wearing Dreem properly, please visit our dedicated article "Put your Dreem headband on".
- Sensors from your front band are dirty. Make sure you clean them with a desinfectant swipe every 10 nights to make sure that front sensors can get an optimized signal.
If you are still getting this error message, please contact our support service.
