About Silvair

Silvair is a rapidly growing company developing innovative IoT technologies for the smart lighting industry. We provide advanced software solutions for wireless lighting control and commercial building automation.

As a leading contributor to the Bluetooth SIG, we drove the development of Bluetooth mesh - a new communication standard for the Internet of Things. We were the first company in the world to develop a qualified Bluetooth mesh stack, and the first IoT business listed on the Warsaw Stock Exchange. Now we aim to be the world’s no.1 provider of wireless solutions for professional lighting applications.


Cloud and edge computing play a crucial role in IoT systems. We use such architecture in monitoring & management of IoT devices via edge gateways. Our platform facilitates devices’ configuration and provides insight into data coming from many IoT networks that can be used by multiple downstream services, enabling users to supervise their lighting infrastructure from any place in the world. Both areas require a software architecture which takes into account a complex ecosystem of cloud, edge and IoT components.
