Lighting of Špilberk Castle – When Modern IoT Enhances Historical Heritage
How can you modernize lighting in a protected heritage site without disturbing its unique character?
This episode explores how IQRF® wireless technology enabled the complete renovation of lighting at Špilberk Castle in Brno — with zero new cabling and no intervention into historic walls.
In this episode you'll learn:
- How IQRF® ensures reliable communication even through thick castle walls using a robust mesh network.
- How the number of spotlights increased from 70 to 96 while reducing power consumption by 44%.
- Why the return on investment is just 4 years, and how the city saves over 1 million CZK annually by eliminating mobile lighting rentals.
- How the new lighting is integrated into Brno's central control system, including multiple preset lighting scenes for events.
- How wireless deployment simplified installation and maintenance — no digging, no new cabling, no damage to the monument.
- How the system can be expanded with additional IoT sensors (air quality, noise, parking occupancy, etc.).
IQRF® shows that modern wireless technology can enhance historical locations with respect, precision, and zero visual impact.
