I think Sok Puppette's comment sums it up well.Less Is More When It Comes To Sensor Power
It used to be the cost of a microcontroller was a big inhibitor to putting brains in everything, but those days are long gone. Even 32-bit CPUs are now cheap enough that you can throw them into any…hackaday.com
The sensor can measure temperature, humidity, pressure, magnetic field, and acceleration on three axes. The device claims to harvest energy from radio frequencies, vibrations, small temperature differentials or light, even indoors. Our guess is that the sensor package runs on very little and when you poll the device wirelessly, the incoming radio signal supplies power for communication. The company claims its device uses 1000 times less power than competing solutions.

Well, I don’t know what “ecosystem” means here, but, yeah, they talk about “accounts”, which means it’s apparently cloud dependent, which makes it a total non-starter. The only thing dumber than making your own house or facility dependent on somebody else’s cloud is making your *customers’* systems dependent on somebody else’s cloud.
You also have to buy their gateway, but having their own RF protocol is more understandable.
One hopes that $600 for two sensors and a gateway is a temporary thing to make sure limited early supplies only go to people who are serious about building something.
