This is running Dev 1.6.0 , so beware. You will have to convert it to 1.5.0 if you aren't running crazy like me!
Edited: There was a bug in the code where it had an unroutable IP address along with a script hosted at Google. Fixed.

I am looking at an Arduino code rewrite using FastLED. But for right now, this works and works well.
I think I might have found a bug in the 1.6.0 beta MySensors. I need to confirm it's not my coding, but because of that, expect Speed call to change internally. Ideally, the API will stay the same, or be added to.
I will replicate with my ServoActuator to see if it's my coding or the beta.

FastLED Arduino sketch is done, along with appropriate Node-red subflow and website.
And it was surprisingly easy! FastLED is a cinch to work with :)

Hello,
I know this is an old post.
But i am trying the script getting to work in combination with Domoticz.
A did a little rebuild to 2.1.0, and i am getting a RGD light which i can switch to dimmable in Domoticz.
I can select color and dim the strip but i am struggeling with the Speed (V_VAR2) and Mode (V_VAR1).
How can I adress these two in Domoticz so it is picked up by the node?
So i want to set the mode and or the speed from Domoticz to.// Enable debug prints to serial monitor #define MY_DEBUG // Enable and select radio type attached #define MY_RADIO_NRF24 //#define MY_RADIO_RFM69 #define MY_RF24_PA_LEVEL RF24_PA_MAX // Enabled repeater feature for this node #define MY_REPEATER_FEATURE #define MY_NODE_ID 9 #include <MySensors.h> #include <DHT.h> #include "FastLED.h" FASTLED_USING_NAMESPACE #if defined(FASTLED_VERSION) && (FASTLED_VERSION < 3001000) #warning "Requires FastLED 3.1 or later; check github for latest code." #endif #define DATA_PIN 3 //#define CLK_PIN 4 #define LED_TYPE WS2811 #define COLOR_ORDER GRB #define NUM_LEDS 60 CRGB leds[NUM_LEDS]; uint8_t gHue = 0; unsigned int currentSpeed = 0 ; int brightness = 96; unsigned int requestedMode = 0 ; int messageType = 0 ; int previousMessageType = -1; String hexColor = "000000" ; unsigned long previousTime = 0 ; void setup() { delay(1000); Serial.begin(115200); FastLED.addLeds<LED_TYPE, DATA_PIN, COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip); FastLED.setBrightness(brightness); FastLED.show(); } void presentation() { sendSketchInfo("FastLED Node", "1.0"); present(0, S_RGB_LIGHT, "Makes strip said color", true); } void loop() { switch (messageType) { //************** CASE 1 ************** case (1): Serial.print("Hex color override: "); Serial.println(hexColor); colorWipe(); messageType = 0 ; break; //************** CASE 2 ************** case (2): if ( (previousTime + (long) currentSpeed ) < millis() ) { if (requestedMode == 2) {rainbow(); FastLED.show(); } if (requestedMode == 3) {rainbowWithGlitter();FastLED.show(); } if (requestedMode == 4) {addGlitter(80);FastLED.show(); } if (requestedMode == 5) {confetti();FastLED.show(); } if (requestedMode == 6) {sinelon();FastLED.show(); } if (requestedMode == 7) {bpm();FastLED.show(); } if (requestedMode == 8) {juggle();FastLED.show(); } previousTime = millis(); } break; //************** CASE 3 ************** case (3): // Adjust timing of case 2 using non-blocking code (no DELAYs) Serial.print("Case 3 received.
