I think I ran into the same general issue years ago when I first got my HE, but I've decided to try and tackle it again. I can't seem to get scenes to show activated consistently and it's causing some havoc with indications on my scene control panel. I would really appreciate some insight into what might be going on.
From what I can see the scene should be activated, but right at the end of the logs the indicator turns off anyway. Sometimes (not often) when I click activate scene again several+ minutes later it will show the scene is on, but I would think any delta states would show in the parenthesis after the scene state which are obviously not shown.
Scene before clicking Activate Scene:
Scene after clicking Activate Scene and waiting for a few seconds:
Log activity on the scene itself:
And when activating a few minutes later:
With correlating "Scene is On":
