NightOwl App - Error Code 08 (ECO8)


Uh oh! Looks like there were some problems with last night’s sleep study. Not to worry, let’s walk through on how we can fix this.


It seems like your smartphone cannot maintain a constant Bluetooth connection with the NightOwl sensor.  You may have noticed a blue light flashing on the sensor during the sleep test as your NightOwl sensor was trying to reestablish the connection.

This could be caused by the NightOwl sensor being out of range of the smartphone. We advise you keep your smartphone within a 2 meter radius of your bed.

If your NightOwl sensor was already within range, the issue could be with your smartphone. You can avoid this issue by using an alternative smartphone or tablet. Open the instruction email we sent you on your new smart device. Follow the steps in the email to download and configure the app. You should be able to continue your home sleep study for the remaining nights.
