Paulmann's 'Gent 2 Remote Control', with product code 50140, uses the Zigbee 3.0 standard, but compatibility with older Philips Hue lamps is not guaranteed.

- Philips Hue lamps use the Zigbee Light Link standard, which is not always compatible with Zigbee HA devices or other Zigbee devices not specifically designed to work with the Philips Hue bridge.
- The Gent 2 remote control can control Zigbee 3.0 products from various manufacturers, but compatibility with specific Philips Hue lamps is not explicitly confirmed by Paulmann.

For guaranteed compatibility, it is advisable to check the specifications of the device and consult the official documentation of both manufacturers or contact Paulmann and Philips Hue customer support.
