Exilight Oy is a company founded in 2003 that specializes in emergency lighting.


Exilight wanted to create a modern, reliable and easy-to-use emergency lighting system. Traditional systems required complex cabling and were laborious to install and monitor.


The solution was the ExIoT system, which consists of luminaire units connected wirelessly to each other via the Wirepas mesh network. Gateway units connect the system to the Azure Iot Hub.

The devices are installed by reading a QR code via smartphone camera view. The user is able to monitor the structures and the luminaires in them from an interactive map and a floor plan. The system will make an alarm if the luminaires need maintenance.


Thanks to automated tests and reporting, the reliability and dependability of the emergency lighting system improved significantly. Wireless communication reduced cabling and simplified installation and maintenance work by reducing costs and freeing up staff resources for other important matters.

Efficient use of cloud services provides scalability, performance, and cost predictability.


The ExIot system is in the maintenance phase. Major integrations have been implemented into the system as a part of further development work.

I think this project as a whole was a great example of an effective collaboration between companies.
