Useful with: node-red-contrib-homekit | node-red-contrib-homekit-bridged

Expected input

Output of HomeKit light accessory, any of the following:

• msg.payload.Hue {float} 0.0 to 360.0
• msg.payload.Saturation {float} 0.0 to 100.0
• msg.payload.Brightness {int} 0 to 100
• msg.payload.ColorTemperature {int} 140 to 500

Or, to convert from RGB, all of the following:

• msg.payload.r {int} Red channel 0 to 255
• msg.payload.g {int} Green channel 0 to 255
• msg.payload.b {int} Blue channel 0 to 255

Or, to convert from XY, all of the following:

• msg.payload.x {float} X channel
• msg.payload.y {float} Y channel

Output

The original input message (pass-though), plus all of following conversions (rgb, hsb, xy, megakelvin)

• msg.payload.r {int} Red channel 0 to 255
• msg.payload.g {int} Green channel 0 to 255
• msg.payload.b {int} Blue channel 0 to 255
• msg.payload.x {float} X channel
• msg.payload.y {float} Y channel
