Hi There!
Been playing around and used some great Sensors. Really love this sh#t 
I try to combine some sensors for my kitchen:
3 Dallas temperature sensors
1 Motion Sensor
1 RGB strip
1 Door (refrigerator)
I think I have somewhere messed up my code.
Not sure what I've done.. Motion, Door and RGB Strip works but I don't see any Temps.

PROJECT: MySensors / RGB test for Light & Sensor
PROGRAMMER: AWI/GizMoCuz
DATE: september 27, 2015/ last update: October 10, 2015
FILE: AWI_RGB.ino
LICENSE: Public domain
Hardware: Nano and MySensors 1.5
Special:
uses Fastled library with NeoPixel (great & fast RBG/HSV universal library) https://github.com/FastLED/FastLED
Remarks:
Fixed node-id
Added option to request/apply last light state from gateway
Domoticz typicals - 2015 10 10:
- Domoticz is using HUE values internally, there might be a slight difference then using direct RGB colors.
