An anonymous reader quotes a report from MacRumors: Last year, Apple, Amazon, Google, and the Zigbee Alliance, which includes Ikea, Samsung, and Philips, announced a new working group known as “Project Connected Home over IP” that set about developing an IP-based open-source connectivity standard for smart home products, with a focus on increased compatibility, security, and simplified development for manufacturers. The group has today announced a major update on the project, stating that development is ongoing, and that work is on track for a 2021 release. The update reveals the first concrete information about how the open-source smart home standard will work. A large number of devices will be supported by the protocol, including “lighting and electrical (e.g., light bulbs, luminaires, controls, plugs, outlets), HVAC controls (e.g., thermostats, AC units), access control (e.g., door locks, garage doors), safety and security (e.g., sensors, detectors, security systems), window coverings/shades, TVs, access points, bridges and others,” as well as additional “consumer electronics products.” The announcement also reveals that the group has grown significantly, now with 145 active member companies. Between these companies there are hundreds of product, engineering, and marketing experts, working across 30 cross-functional teams to deliver the new standard. The group aims to provide a “draft specification” by the end of the year, and release the completed standard next year. Read more of this story at Slashdot.
