Dotdot is the universal language of the Internet of Things, making it possible for smart objects to work together on any network. It represents the next chapter in the Zigbee Alliance’s continued commitment to create and evolve open standards for the smart networks in our homes, businesses and neighborhoods.

Most IoT devices don’t speak the same language even if they use the same wireless technology. With Dotdot, Zigbee devices can speak a common language at the application layer. Dotdot can also be applied across other IoT networks.

Dotdot has been developed by the Zigbee Alliance — an open, global, non-profit organization.

Dotdot is a common language for the smart objects we rely on every day, so they can speak to each other effortlessly on any network, and make themselves more useful to all of us.

Discussion

  • What's the need to have Dotdot?
    Dotdot Overview. Source: speakdotdot,2017.

    In the Internet of Things, every smart device must understand and speak the same language at the application layer. How else is a smart hub expected to know how to communicate and control an off-the-shelf door lock or thermostat? Without a common application layer, devices from different networks (Wi-Fi, Thread, Bluetooth, Zigbee) can’t communicate.

    Dotdot is an open standard that can run over many networks allowing smart objects to communicate. Dotdot is based on the mature, proven solutions of the Zigbee Alliance. It is the product of 10+ years of work and experience from hundreds of innovative Zigbee Alliance member companies from across the industry and around the world.

  • What are the benefits of using Dotdot?

    Dotdot has the following benefits:

    • Single solution for all markets - A single application layer that works over many networks means a single choice for developers and consumers, and an end to market fragmentation like Home, building, industrial, retail, health, energy, and more.
    • Easy - All necessary documents, references and tools are available in a single location and a single certification mark on every certified product and package.
    • Secure - Since application level DTLS sessions, Operational certificates and Access Control Lists (ACLs).
    • Global - Built on the open standards and global membership of 400 Zigbee Alliance members.
    • Proven - Dotdot is based on the Zigbee Cluster Library (ZCL) that is deployed in over 300 million products for over 10 years.
    • Reliable and robust - Dotdot brings a rich catalog of device interaction models to IP networks. This enables devices to interoperate natively, while being able to interact with similar/complimentary devices on a Zigbee network.
    • Interoperable - Certification ensures device-to-device interoperability, a single application language enables and connects multi-vendor ecosystems.
  • Where does Dotdot fit among layers of the protocol stack?

    Dotdot can be can be connected to any network type including Bluetooth, Wifi, Zigbee, or Thread.

  • What are the alternatives to Dotdot?
    • IoTivity
    • IPSO Alliance
    • Open Connectivity Foundation (OCF)
