Question about Philips Hue Festavia (Swiss plug)

You can control the light chain via the Philips Hue app using Bluetooth without necessarily needing the entire Hue system or the Hue Bridge. The app allows basic functions such as on/off, dimming and colour change. However, the Hue Bridge is recommended for advanced functions such as automation, remote control and smart home integration. The app is therefore sufficient for basic control, but the Bridge significantly expands the possibilities.
