Standalone smartwatches like Lemfo Lem8

Does Sleep as Android work on standalone smart watches like the Lemfo Lem8?
In particular, are the sensors on these devices (eg. heart rate monitor, accelerometer) supported?

Hey Dan,

if the watch runs full Android, then Sleep as Android should work. We don’t guarantee the looks and usability as we haven’t tested this ever, but functionally there should be no issues.
One exception is the heart rate sensor - we don’t have support for an on-board sensor as we assume HR will always be received from another wearable.

Thanks for the reply Jiri.

In that case, is there a Wear OS or Tizen smartwatch in which the heart rate monitor and smart wake functions can work on the smartwatch independent of a smart phone?
