This is probably a result of an authentication error. I'll admit, the error checking on this isn't up to what I'd normally do - I wrote it in the early months of my kid's life when I was sleep deprived and short on time :D I'd recommend double checking to make sure that the "username" is the email address you use to log into your account and not any actual username.

I double checked, it is and was the email.

I double checked, it is and was the email.

If you're based in Europe, as I am, then you need to change the region value on the sensor to "europe". I had the same issue and resolved it by doing that, as mentioned in the mbevand/owlet_monitor repo readme :)
