T-OI plus ESP32-C3

The red LED should be switched off to get minimum current consumption during deep sleep.
A solder bridge would be helpful.
At default initialization I get the following value reading the TOUT:

E (798844) tsens: Do not configure the temp sensor when it's running!
E (798844) tsens: Temperature sensor is already running or not be configured
ADC analog value = 2954
ADC millivolts value = 1407
Core temperature = 44.6 °C

I expect 1/2 VBAT, also about 1900 mV.
Why I get the two messages tsens: ...

This is my program:

void setup() 
{
  Serial.begin(115200);
  
  analogReadResolution(12);
  analogSetAttenuation(ADC_11db); 
}

void loop() 
{
  // read the analog / millivolts value for GPIO2:
  int analogValue = analogRead(2);
  int analogVolts = analogReadMilliVolts(2);
  float temp = temperatureRead();
  
  // print out the values you read:
  Serial.printf("ADC analog value = %d\n",analogValue);
  Serial.printf("ADC millivolts value = %d\n",analogVolts);
  Serial.printf("Core temperature = %3.1f °C\n\n", temp);
  
  delay(2000);  // delay in between reads for clear read from serial
}
