Yeah, there have been about 4 threads asking this question in the last few months, but so far I haven’t seen any definitive answers. It’s confusing. 
Hopefully somebody will respond to this thread, at which point I can combine them all together. But for now, I honestly don’t know.
@Mariano_Colmenarejo might know some…
I’m going to add the links to the other recent threads on this topic, just so it will be easier to pull them all together once we do get some answers.
Some of these topics are asking questions about the energy dashboard in the smartthings app, but they mention that they have plugs that used to report energy consumption in the old architecture, but are not in the new architecture. So I’m still waiting to see some definitive brands/model examples of devices which do report via edge drivers. 
How to get alerts with power usage with smart plugs (which brands work?)
