NightOwl App - Error Code 08 (ECO8)

Find out why this error code is appearing on your sleep test.

Uh oh! Looks like there were some problems with last night’s sleep test. 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.

This could be caused by the NightOwl sensor being out of range of the smartphone. We advise you keep your smartphone within a 2 metre 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 test for the remaining nights.
