Sniffing data from Philips Hue Lamp

Hi,

I am a research student and wondering if someone could please help me?

I have a Philips hue lamp and looking to sniff data from Philips hue lamp connected to wireless router using Ethernet cable. To switch lights on/off I use hue app installed on my mobile phone and using wireshark to generate capture network traffic.

Could anyone tell me how to sniff data from these lamps? and is there any possibility to decrypt packets generated from Zigbee protocol.

Regards

Usman
