It feels like this is already a mostly-solved problem. The wireless switches/sensors/bulbs are already handled by various things in the Zigbee ecosystem. RF energy harvesting is already a thing[0]. I've even got a Zigbee switch[1] that uses the energy from pushing the button to power its transmitter. Turning lights on and off based on occupancy is also a solved problem, as is HVAC zoning. The only innovation here is to combine the various pieces into one package. Hopefully it uses an existing standard like Zigbee, ZWave, or Thread/Matter instead of inventing something new and incompatible. I am 100% on board with anything that eliminates the need to change batteries in all of these devices.

  Integration is not innovation.

  It is, but honestly this feels pretty weak. There are already a bunch of Zigbee energy harvesting switches on the market that work well. There's the Hue Tap that I mentioned, plus other commenters have pointed out other ones. If you replace the "one or two RF power transmitters to power up all switches inside the house" with a Zigbee gateway you've got a packaged solution that you can buy right now. The rest of the article talks about sensors, "seamless automation", etc and feels like future thinking (i.e., they don't have a solution here but they're working on it), but also feels like more already-solved problems. For example, lighting driven by occupancy is something you can easily do by adding a Zigbee motion sensor to the system. HVAC zoning is also a thing, but a lot more complicated as it requires dampers and needs to be designed as a complete system. You can't simply open the dampers for just the occupied rooms, you have to keep in mind that the furnace needs to maintain a minimum amount of airflow so that it doesn't overheat. You could also go with a mini-split heat-pump system where each major room (e.g., bedrooms and living rooms) will basically have its own HVAC system. I doubt that the costs of a zoned HVAC system would ever pay for itself in energy savings vs, e.g., an Ecobee thermostat plus sensors (another off-the-shelf solution that you can buy right now).
