NovaLight OLC Zhaga luminaires controllers are officially Zhaga-D4i certified! This standard harmonizes the operation of intelligent equipment connected to luminaires. Controllers and sensors from different manufacturers can now interoperate. This openness of solutions gives towns and cities greater flexibility to choose the remote management system they prefer, and the most effective sensors for their specific use cases. Novaccess is convinced that interoperability plays an essential role in the establishment of a "smart city", and so strives to make itself compatible with as many standards as possible that enable this.
