Question about Philips Hue Festavia (Swiss plug)

For the Philips Hue Festavia light chain, especially the 40 m version, the Hue Bridge is not absolutely necessary to change the colours or brightness via telephone, but it does offer some advantages:

- Without the Hue Bridge, you can control the fairy lights via Bluetooth and the Philips Hue app. This enables basic functions such as on/off, dimming and selecting preset scenes.
- With the Hue Bridge, however, you can use the full range of functions of the light chain, including automations, remote control via the Internet and more comprehensive integration into your smart home system.

So if you only need the basic control functions, the Bluetooth connection is sufficient. However, for more comprehensive control and integration into your smart home system, the Hue Bridge is recommended.
