The ZigBee Alliance has unveiled its latest attempt to consolidate the fragmented state of the IoT market, to extend IoT interoperability beyond its familiar haunt in the network protocol. Called dotdot, the new specification is looking to enable existing ZigBee developers to get their claws into wider ecosystems that, potentially, opt to support dotdot, and hopefully unite the disparate IoT protocols under a common banner. dotdot is being positioned as a universal language for the IoT, which could be used by many other physical layers than just ZigBee – such as direct mesh networking rivals like Z-Wave and the 802.15.4 brother that is Thread, but also other low power PHYs that are less well-known, or even future evolutions of standards…
