Ditto, but with z-wave devices instead. What makes you think CHIP is the next standard thats up for mass adoption when there is a bunch of competition in this space, with the likes of Sidewalk from Amazon or Thread which I think is what Apple are rolling out to the homekit enabled devices?
Amazon and Apple are both members of the CHIP working group. As far as I know, CHIP uses Thread as one of it's protocols (the other being a BLE derivative). Sidewalk uses WiFi, which is not very efficient for low-powered devices (eg. sensors, switch etc.)
Well to be honest, I really like the open-source approach that they have decided on for the development of the standard. You can follow the development of it's reference implementation on the Github repo of the project: https://github.com/project-chip/connectedhomeip
