On Tuesday, ZigBee announced Dotdot, which it calls a universal language for IoT. Even though ZigBee is best known as an open wireless communications protocol used in many home IoT products, Dotdot is intended for use with any wireless technology. It defines things like how devices tell each other what they are and what they can do, which is important for making different objects around a home do things together.
