lightonhandler setting fine but no light

Hi ,

Am pretty new to home automation and ws8266. I have setup the following

WS2812B based LED strip and has 60 LEDs NodeMCU with WS8266 I have connected the 5v 4amp power supply to volt(red wire) and gnd(white) of LED strip And from the same power supply i have fed the power to 3-5v logic shifter through the 5v input and gnd using the power out at the end of the led strip i have powered the nodeMCU Vin and gnd pins I have connected D4 of nodeMCU to DataIn(green cable) of the LEDstrip through the Logic shifter

The following is my code

#include <Homie.h>
#include <Adafruit_NeoPixel.h>

#define FW_NAME "led-control"
#define FW_VERSION "1.0.0"

#define PIN            4
#define LED_COUNT      60

Adafruit_NeoPixel strip = Adafruit_NeoPixel(LED_COUNT, PIN, NEO_GRB + NEO_KHZ800);
int delayval = 500; 
int showType = 0;
int SoffitR;
int SoffitG;
int SoffitB;
int numPixels = LED_COUNT;

HomieNode ledNode("led", "led");

bool lightOnHandler(HomieRange range, String value) {
  Serial.print("Light On Handler");
  if (value == "off") {
    colorWipe(strip.Color(0, 0, 0), 50);    // Black/off
    //Homie.setNodeProperty(ledNode, "color").send("0,0,0,0");
    ledNode.setProperty("color").send("0,0,0,0");
  } else if (value == "red") {
    colorWipe(strip.Color(255, 0, 0), 50);  // Red
    ledNode.setProperty("color").send("0,255,0,0");
  } else if (value == "green") {
    colorWipe(strip.Color(0, 255, 0), 50);  // Green
    ledNode.setProperty("color").send("0,0,255,0");
  } else if (value == "blue") {
    colorWipe(strip.Color(0, 0, 255), 50);  // Blue
    ledNode.setProperty("color").send("0,0,255,0");
  } else {
      //value.trim();
      Serial.print (value);
      //Serial.flush();
      // split string at every "," and store in proper variable
      // convert final result to integer
      SoffitR = value.substring(0,value.indexOf(',')).toInt();
      SoffitG = value.substring(value.indexOf(',')+1,value.lastIndexOf(',')).toInt();
      SoffitB = value.substring(value.lastIndexOf(',')+1).toInt();
      colorWipe(strip.Color(SoffitR, SoffitG, SoffitB), 50);
      ledNode.setProperty("color").send(value);
      Serial.print("Value Set to LED");
  }
  return true;
}

int i;

void colorWipe(uint32_t c, uint8_t wait) {
for(uint16_t i=0; i<strip.numPixels(); i++) { //<strip.numPixels
strip.setPixelColor(i, c);
strip.show();
delay(wait);
}
}

void setup() {
  Serial.begin(115200);
  Serial.println(FW_NAME FW_VERSION);

  strip.begin();

  Homie_setFirmware(FW_NAME, FW_VERSION);
  ledNode.advertise("color").settable(lightOnHandler);

  Homie.setup();

}

void loop() {
  Homie.loop();
}

I have uploaded the json config also through ESP8266 uploader { "name": "LED for TV Stand", "device_id": "family-room-tv-led", "wifi": { "ssid": "ABCDEF", "password": "mypassword" }, "mqtt": { "host": "192.168.0.123", "port": 1883, "base_topic": "devices/", "auth": true, "username": "username", "password": "password" }, "ota": { "enabled": true } }

this is my openhab config item String TVLedLightColor (All) {mqtt=">[broker:devices/family-room-tv-led/led/color/set:command:*:default]"}

When i try to set a color this is what it shows in the Serial Monitor Hardware device ID: 6001942bdf7c • Device ID: family-room-tv-led • Name: LED for TV Stand • Wi-Fi: ◦ SSID: ABCDEF ◦ Password not shown • MQTT: ◦ Host: 192.168.0.123 ◦ Port: 1883 ◦ Base topic: devices/ ◦ Auth? yes ◦ Username: username ◦ Password not shown • OTA: ◦ Enabled? yes ↕ Attempting to connect to Wi-Fi... ✔ Wi-Fi connected, IP: 192.168.0.125 Triggering WIFI_CONNECTED event... ↕ Attempting to connect to MQTT...

The bolded text or my debug code But still the light does not come on. LED strip is off. Please can you tell what else can i try?
