Sweet! Thanks for posting those, I didn't know about either device.
That's the beauty of procrastination, if you wait long enough more clever products start popping up. The "Span" is another smart load center like the Leviton in
#6. The Lumin is cool, looks like it can control twelve lines, but only has
two current transformers, and can go to 4? Wonder how well the lumin can make use of
excess solar power (its a tricky problem, for example on my system the microinverters get throttled back so they're only producing what I'm consuming, but if you knew how much power was actually available you could, for example, turn on car charging if there was enough).
For me, the perfect product would be inexpensive circuit breakers I could retrofit in my Square D (that both allowed remote on/off as well as current measurements) as the load center is an interior hallway.
On the upside,
15 amp smart sockets with power monitoring built-in are fairly inexpensive now. Haven't seen much beyond 15 amps through.
...the ability to load shed ...
[In TV Ronco announcer's voice] Now you too can cause rolling blackouts within your home just like the Grid Operators!
...Thanks for bringing us all down the rabbit hole...
