Grove Base Kit Multiple I2C Connection
About two weeks ago there was a change in the Arduino_SensorKit Library that introduced an error with the instanciation of the Oled object.
I found the error in the release (v1.0.6) of the library. The previous release (v1.0.5) could cause another issue, as it uses a software I2C. I doubt the hardwired sensores are connected with the correct pins. But I have no hardware, so I can not check this.
I propose a workaround to see, if the identified issue caused your observations.
#include &quot;Arduino_SensorKit.h&quot;

U8X8_SSD1306_128X64_NONAME_HW_I2C Oled2;
// if the line above does not work
// comment it and uncomment the following line.
// U8X8_SSD1306_128X64_NONAME_HW_I2C Oled2(U8X8_PIN_NONE);

void setup() 
{
  Oled2.begin();
  Oled2.setFlipMode(true);
  Oled2.setFont(u8x8_font_7x14B_1x2_r);

  Pressure.begin();
}

void loop() 
{
  Oled2.clear();
  
  Oled2.setCursor(0, 10);
  Oled2.print(&quot;Temp: &quot;);
  Oled2.print(Pressure.readTemperature());
  Oled2.print(&quot; C&quot;);

  delay(1000);
}

Could you please try out and report your experience.
If it would work, I can support the fixing of the issue.
