[solved] Philips Hue and LIFX RGB-sync

[jeremy8810]

Hi There,

I am a bit new to coding with the function-node. What I am trying to do:

I have Philips Hue lights and LIFX lights.

When I change the color of the Philips lights, I want to send this to the Lifx lights to change in the same colour.

The output of Philips is done by an array (if I'm right), like this:
payload:
0 : 255
1 : 255
2 : 255

I need to change this format to just be comma-seperated like:
payload: 255,255,255

I made the following function-node:

var red = msg.payload[0]
var green = msg.payload[1]
var blue =  msg.payload[2]

return [ red, green, blue ];

But it's still returning as:
payload:
0 : 255
1 : 255
2 : 255

How can I change this?

Please help me out, thanks!

Try

msg.payload = red+","+green+","+blue

Hi Zenofmud,

Thank you for the reply.

The following error is returning now:

Take a look at that link, rather than returning the payload, return a message object.

Nevermind,found it, had to remove the ".payload" in my return rule.

Thank you for helping me out!
