Use the IQRF DALI bridge, which you simply plug into your light with the DALI interface.
Light control commands – switching off, switching on, changing the intensity of lighting, etc. – are then sent over the IQRF wireless network. This device allows communication with a DALI-enabled device over the IQRF wireless Mesh network.
Connecting to your light-supporting DALI standard is simple and requires no special and expensive development.
