Casambi is developed in Finland. It became widely used and popular among professional LED lighting producers and solutions because of it´s cost effectiveness, ease of use and scalability.
Wireless Mesh Network
On top of Bluetooth Low Energy, the Casambi technology provides a mesh network where all the intelligence of the system is replicated in every node and, in such a way, creates a system with no single points of failure.

Such self-organizing wireless mesh network can control a large number of fixtures from any point. It also allows for firmware updates over the network, allowing any kind of changes to be made over-the-air. In this kind of fully distributed and symmetric architecture, any unit can go offline and catch up from others when they return back online.

The Casambi devices are smart on their own and only connected when needed. An Internet connection is not necessary for normal operation, it is just needed for user interface configurations to be sent or recalled from the cloud service.
