Thanks: appreciate all the detail! Excellent report.
One small point: It’s not the first third-party smart plug to show up in the energy feature in the smartthings app: I believe aqara was. But it does show up there.
However, you won’t be able to use energy draw in routines if you connect it through matter because at the present time matter doesn’t support energy reporting. As you mentioned, that may change in the future.
Also, for those who didn’t already see my post in the other thread, “energy reporting“ can mean three different things in a smartthings context, and an individual device might support any combination of the three, which can get confusing. Here’s the link to the post with those details.
