I've been thinking about getting and Emporia and searching around I saw that there's a project on github to extract data using Python.
https://github.com/magico13/PyEmVue
I have no idea if it works, but it might be worth taking a look.
Also would be interested in this. I've looked but haven't found anything that has 2 voltage inputs (for split-phase) and 20-40 current inputs. Tempted to build it myself, basically a bunch of these[0] on a common backplane, but haven't got around to it yet

At least the ones I have seen are not. I am able to read the all the power meters in my building with a cheap USB SDR and this software.

I have not gotten around to figuring out which one is mine or a good way to system to store/display the data but I certainly can read the date.
In the grand scheme of things it is a minor to medium security flaw, power usage could be used to infer which houses contain valuable items and when people are home. I'd say medium at most since a lot of other things Visible curbside indicate this as well (lights, cars in the driveway, etc.). On the other hand, electronics are pretty efficient. A wealthy house with all the lights on is still using less electricity than a small apartment using an electric stove. But I guess if you were really interested in stealing electric cars then it would be really useful.
There are a lot* of cheap 2.4Ghz wireless outlets that can be flashed with custom firmware that supports power usage & outlet control over MQTT & other protocols. Keep in mind that these devices have to be manually configured & calibrated.

* Some new versions of these outlets come with firmware that can not be patched/flashed so do some research.
Also most of these are limited to 10 amps of restive load... inductive loads like motors, compressors, and to an extent power supplies, will have peak loads 3-4x there 'real' consumption which can damage the relay if its not rated for the high initial load. If anyone knows of a cheap alternative or cheap DIY that can handle +20A I would be very interested as it would be nice to be able to control things like fridges without worrying the outlet will fail closed & my food will spoil.
