DALI-2 IoT Gateway is an interface to connect the DALI system with smart devices over the Internet of Things (IoT). With the DALI IoT Gateway, a simple realization of an intelligent system is possible, in which devices can be controlled and monitored with smartphones, PCs, etc. It is also possible to link several DALI lines. An API documentation is available, to enable energy monitoring, remote support, and many other applications. (RESTFul API endpoints and WebSocket with JSON syntax, encrypted (optionally unencrypted) for custom integrations).
