Additional information:

The Android Wear application was fully configured using the Home Assistant Android application on the phone because my installation uses MFA.

The Home Assistant installation is still in its infancy. Only one light is configured there.

The root cause is not about rotary bezels, feelings, or whether it is better or worse. It’s really a backward compatibility issue.

The vertical scrolling factor reading code, as it is written today, does not work with older Android/Wear versions because the Java reflection API is being used incorrectly. The mistake is easy to overlook but also easy to fix.

I’ll submit a PR next week.

Happy new year.

One more thing @dshokouhi https://github.com/dshokouhi: I looked at #2092 https://github.com/home-assistant/android/pull/2092 and it looks like the call to invoke() on the Method instance returned by getDeclaredMethod() https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#getDeclaredMethod-java.lang.String-java.lang.Class...- is missing. toString() is invoked directly on the Method instance, which will never produce the float value you’re looking for.

Take a look at the implementation of ViewConfigurationCompat https://android.googlesource.com/platform/frameworks/support/+/refs/heads/oreo-dev/compat/java/android/support/v4/view/ViewConfigurationCompat.java for an example.

Maybe it is a good idea to use ViewConfigurationCompat::getScaledVerticalScrollFactor https://developer.android.com/reference/androidx/core/view/ViewConfigurationCompat#getScaledVerticalScrollFactor(android.view.ViewConfiguration, android.content.Context) instead? 😉

Many people are using this current workaround while we wait for Google to add native rotary support. As of now this is just temporary and we are even using Google’s recommendation here. If you feel it’s better feel free to submit a PR, we are open source. For those of us with working bezels the code is working for us as is.

The watch does not have a working/rotary bezel if that’s what you mean. See: https://www.lg.com/us/smart-watches/lg-W150-lg-watch-urbane
