Trying to control many Philips Hue using Hue Magic individually, but fail in passing the id as a json

[vongomben]

Hi.
I'm trying to design a control system based on Node-RED and 20 Philips Hue.
I want to control them individually via JSON.

From the documentation can also apply settings in universal mode to a specific light by transferring the corresponding light ID as a string in msg.topic together with your settings.), I read:

You can also apply settings in universal mode to a specific light by transferring the corresponding light ID as a string in msg.topic together with your settings.

I hoped this may work with the light id too. it doesnt.
What I'm loogking for is to send a message to all the bulbs with the behaviour of the bulb I want to control.

Any help?
