Grove Sunlight Sensor Library doesn't Work

Products & Technology Grove
#1

Hi, Ive bought 2 Grove Sunlight Sensors from the Arduino Store (Advertised as Rev. 1 with Si1145 Chip) but recieved the Rev. 2 (Si1151 Chip?) and Ive attempted to communicate with the sensor using the 1151 Library, but It doesnt work
Using a Nano RP2040 / MKR WiFi 1010 with Arduino IDE 2.2.1
The I2C Connection does get recognized

Using a Library from Grove - Sunlight Sensor | Seeed Studio Wiki

#include <Wire.h>

#include <SI114X.h>
#include <Si115X.h>

Si115X si1151;

#define WIRE Wire

/**
 * Setup for configuration
 */
void setup()
{
    uint8_t conf[4];

    Wire.begin();
    Serial.begin(115200);
    if (!si1151.Begin())
        Serial.println("Si1151 is not ready!");
    else
        Serial.println("Si1151 is ready!");

}

/**
 * Loops and reads data from registers
 */
void loop()
{
  Serial.println(si1151.ReadHalfWord());
    Serial.println(si1151.ReadHalfWord_VISIBLE());
    Serial.println(si1151.ReadHalfWord_UV());
    delay(100);

  delay(5000);           // wait 5 seconds for next scan
}

but it doesnt recognize “ReadHalfWord”

Does anyone have working Code or a Fuctioning Library for this sensor?
Any ideas how I can troubleshoot this?
