Thx for the feedback!
For #1
We have offered plenty of icons for customized switches. If it affects how you make voice commands via third-party platforms, you can try changing the type there. For instance, apple should be able to change switches/outlets to lights.
For #2
eWeLink has built chips to group up lights/switches on eWeLink WEB. For app, there’s a section on the insight tab for this.
For #3 and #4
These features cost lots of developing resources and API spending and the performance may not meet our standard. The app is heavy with so many features in it, so if you keep it running in the background for location recording, the battery could be drained fast and heat up.
A leave/arrive home scene + widget on the Home screen is more practical
