I’ve noticed that for the notifications to be consistently mirrored to the watch I’ve had to turn off battery optimization for the Wyze app so it is always running in the background. However, because the app not only has the watch functionality but also has all the other cameras, shop, account functionalities it tends to drain the battery quicker.
If you create (separate) an app specifically for wyze watch i think it could reduce the battery drain as it would only have the watch functionalities.
