These products are a lifesaver in places where the electric grid is unreliable. Most Puerto Ricans rely on generators and battery backup devices to power their day-to-day life.
1) At the price point, lower-income countries with unreliable grids are not the target audience. If not that, then who? Off-grid wealthy individuals?
2) This app-controlled system MUST work offline. In wide-scale power outages, diesel generators in cell towers die out or get looted fairly quickly. Cable coax repeaters for home internet stop working almost immediately.
This latter scenario must be first in mind. Telecommunications will be gone in give or take 5 days after a large disaster or outage.
As for positive notes: loving the industrial design and battery mesh idea.
