So manufacturers’ existing products will continue to work with HK and the new ones they develop will work with this new protocol that includes HomeKit. Still not sure what I’m supposed to be worried about here.
The premiss of the new standard is:
The goal of the Connected Home over IP project is to simplify development for manufacturers and increase compatibility for consumers. The project is built around a shared belief that smart home devices should be secure, reliable, and seamless to use. By building upon Internet Protocol (IP), the project aims to enable communication across smart home devices, mobile apps, and cloud services and to define a specific set of IP-based networking technologies for device certification.
Too many competing standards, which all require independent certification. This burdens manufactures and results in higher costs to consumers if they try to support them all. You can interpret simplify how ever you want.
If you already have products based on one of the existing protocols, I would not invest in any new products except to replace a failed device. Once existing products in the pipeline are released to market, future development of new products will likely be discontinued. Once new products adopting the new standards are available, there is no incentive for manufactures to continue support of older protocols.
