The project is a text-book example of how to apply DALI technology.
A Delmatic DALI system provides comprehensive monitoring and management of lighting within the iconic building.
DALI-2 is the global standard for digital dimming, enabling devices from different manufacturers to be seamlessly integrated into interoperable networks.
We offer a wide range of DALI 2 products that can be integrated with other open protocol systems such as LON and BACnet.
Delmatic’s smart lighting solutions seamlessly mesh wireless, wired and mixed-mode controls across physical or cloud networks, continuously monitoring, analysing and optimising lighting and sharing real-time intelligence to optimise building performance.
MQTT is an ISO standard publish/subscribe protocol which is lightweight and designed to minimise network bandwidth and device resource requirements while ensuring reliable and rapid delivery.
Delmatic’s latest IP DALI controllers act as scalable data-rich IoT Edge gateway devices, coexisting in both IP and DALI universes, communicating and sharing strategic data in real-time with configurable MQTT payload.
MQTT’s internet-style, lightweight design minimises network and resource bandwidth while event-driven messaging – more efficient than traditional request/response paradigms – makes MQTT ideal for Internet of Things (IOT) world of connected devices.
The core of MQTT is the client/broker relationship. MQTT Clients publish or subscribe to messages (topics) they are interested in while MQTT Brokers dispatch messages related to the specific topic. In this way, clients only receive the information they are looking for rather than being swamped by unnecessary data.
MQTT is an event-driven protocol supporting real-time change of value (COV). There is no periodic or ongoing data transmission which keeps transmission to a minimum. A client only publishes when there is information to be sent, and a broker only sends information to subscribers when new data arrives.
MQTT makes it easy to encrypt messages using TLS and authenticate clients using latest authentication protocols, such as OAuth.
MQTT was originally developed in 1999 to monitor oil and gas pipelines running through the desert. Monitoring devices were in remote locations where landline, wired, or radio transmission connection was either difficult or impractical.
The only option, at the time, was satellite communication which was very expensive and charged based upon the amount of transmitted data. With many installations comprising thousands of field sensors, the challenge was to develop a form of communication that could provide reliable data using minimal bandwidth – and so, MQTT was born.
And, some twenty years later, it is the same lightweight efficiency that makes MQTT the protocol of choice for today’s Internet of Things.
Delmatic’s latest IP DALI devices – the first to be globally qualified as Smart Ready – are powerful MQTT Edge Gateway devices representing every lighting point and device in a network as a configurable and individual MQTT payload.
Open protocols are at the heart of today’s connected world. They give you choice, economy and efficiency, ensure multiple sources of supply and support, enable sharing of hardware and real time data, and reduce capital and operational costs.
