Got two sets from Amazon resale for about $110. Both looked like brand new. I suggest to look for 30% of Amazon resale during the holiday.

Quote from Poken1151 :
Bought a 4-pack of outlets a few months ago yo further subdivide the energy monitoring. Only two worked. Bought another four pack a year later (so like a couple weeks ago), and none of them "work". Tried reaching out to cistomer supports, they also flailed about. So on third attempt just asked for a refund.
IMO that's kind of irrelevant. Emporia is plenty useful without the rest of their ecosystem. At least it seems most users just pump the data into something like HA
you can also flash it for local use. After two years, I still haven't had the time/need to.
no experience with this product from OP, but if it's at all similar in terms of data access, it's very useful for identifying high-draw circuits, inefficiencies, and predicting your power bill. DIY install is pretty straightforward if intimidating.

Hmm, I have the Emporia Vue (after switching from Sense, which I hear is now being integrated in some Smart Meters...). But Emporia is flailing with the additional hardware. Anyone have or know of a full review of this system? Is it possibly fully local? Or better ecosystem?
FYI I ordered 2 of them to test against my emporia setup and I'll let you know how it goes.

I don't disagree per se, but my condo wiring is a little all over the place. So Its helped me narrow down a... General direction, but could use additional insight.
