I think the problem is that most sleep trackers try to judge sleep based on heart-rate, which I don't think is valid.
There are a few sleep headbands that use an EEG though and in my experience they've been reliable (e.g. mine correctly judges when I actually fall asleep and has correctly judged that I was in REM sleep when I woke up from a dream).
