Hello, I am running an M5Stack Atom Matrix with the U088 TVOC_eCO2 Gas Sensor Unit (SGP30) connected via Grove and I²C. It connects to my Home Assistant and works great.
Now I want to run the sensor with an M5Stack Atom Lite. It is the same chip and almost the same board so even the GPIOs for the Grove connector are the same. I am using the same code but I get “Results from i2c bus scan: Found no i2c devices!”
What am I missing?

Did you ever figure this out?
I can get the SGP30 to work with n Arduino Sketch but not in ESPHome on an M5 Core 2.
Here is the sketch
#include <M5Core2.h>
//SGP30 needs 15 seconds to initialize calibration after power on.
//The screen will display TVOC and CO2
#include "Adafruit_SGP30.h"
Adafruit_SGP30 sgp;
int i = 15;
long last_millis = 0;
void header(const char *string, uint16_t color)
{
M5.Lcd.fillScreen(color);
M5.Lcd.setTextSize(1);
M5.Lcd.setTextColor(TFT_WHITE, TFT_BLACK);
M5.Lcd.fillRect(0, 0, 320, 30, TFT_BLACK);
M5.Lcd.setTextDatum(TC_DATUM);
M5.Lcd.drawString(string, 160, 3, 4);
}
void setup() {
M5.begin(true, false, true, true);
header("SGP30 TEST",TFT_BLACK);
Serial.println("SGP30 test");
if (! sgp.begin()){
Serial.println("Sensor not found :(");
while (1);
}
M5.Lcd.drawString("TVOC:", 50, 40, 4);
M5.Lcd.drawString("eCO2:", 50, 80, 4);
Serial.print("Found SGP30 serial #");
Serial.print(sgp.serialnumber[0], HEX);
Serial.print(sgp.serialnumber[1], HEX);
Serial.println(sgp.serialnumber[2], HEX);
M5.Lcd.drawString("Initialization...", 140, 120, 4);
}
void loop() {
while(i > 0) {

last_millis = millis();
i--;
M5.Lcd.fillRect(198, 120, 40, 20, TFT_BLACK);
M5.Lcd.drawNumber(i, 20, 120, 4);
}
}
M5.Lcd.fillRect(0, 120, 300, 30, TFT_BLACK);
if (! sgp.IAQmeasure()) {
Serial.println("Measurement failed");
return;
}
M5.Lcd.fillRect(100, 40, 220, 90, TFT_BLACK);
M5.Lcd.drawNumber(sgp.TVOC, 120, 40 , 4);
M5.Lcd.drawString("ppb", 200, 40, 4);
M5.Lcd.drawNumber(sgp.eCO2, 120, 80, 4);
M5.Lcd.drawString("ppm", 200, 80, 4);
Serial.print("TVOC "); Serial.print(sgp.TVOC); Serial.print(" ppb\t");
Serial.print("eCO2 "); Serial.print(sgp.eCO2); Serial.println(" ppm");
delay(1000);
}
In ESPHome I get this
