Default SPAN "Smart Home Electrical Panel" - opinions?

An acquaintance sent me this about a startup with a product that can:
"track and control behind-the-meter batteries, rooftop solar inverters, EV chargers and other key household loads via smartphone "
(They did not say it could leap tall buildings in single bound, though)

https://www.greentechmedia.com/artic...attery-markets

IMO, something that had a built-in transfer
switch with a more standard installation for PV battery backup would
be a good thing, but just leave the rest of the loads on a regular
panel.

Anyone have any opinions about this?

I don't see the benefit of putting it into the panel. Anything that you mentioned can already be done separately, better, and more durably. It might not look like a pretty Tesla charger on the fruitcake's garage wall, but it's not supposed to.

My customer wants one of those, but from what I can see from the website, it's not available yet. He wants to pair that up with a couple of Tesla battery packs ahead of getting one of the Tesla solar roofs when those become available. One of the initial problems I see is its only 30 spaces, which I can understand from an engineering standpoint of trying to stuff all of that stuff into one package, something has to give. This house has two subpanels in addition to a full 40 space panel. I've sent a few inquiries and only recently got an automated response back. I'm not sure if they'll sell me one or not. The batteries I have to get from someone else because they won't sell them direct to me either.

In 5-10 years will this company still be around? That includes the software & apps.

My customer is aware of this having owned a couple of software companies himself. He’s a big part of where I am now , so I give him what he wants.

This is why I try and steer my customers towards some of the more open home automation protocols when they want smart devices. Their stuff will keep working when one company goes out of business.

...and as someone pointed out in a thread a good while back, still wire the switch boxes for standard snap switches.

TRENDY! Oh wait, I can do better than that. Ok , from their own article, this gobbledegook, the best part of which I will highlight in red:

Outside of attaching current transformer clamps to every circuit, this level of data granularity is very hard to collect, he said. Energy disaggregation devices from startups like Sense can make do with induction clamps on a home’s electrical mains, but with a loss in accuracy and certainty of measurement, he said. But for the electrical panel, it’s a simple task.
