Have this up and running on a nodeMCU. WLAN ist ok, get data on iobroker/mysensors instance.
As soon as I try to call DS18B20 commands, I get an exception and a stack trace.

DS18B20.requestTemperatures();

What causes this ?

@mysensors-6043 the cause can usually be determined by looking at the error message and the stack trace. Without that information, there is not much we can do to help.

[mysensors-6043]

This is the code, errormessage and stack info follows, many thanks.

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
float prevTemp = 0;
int sent = 0;
int numSensors=0;

void setup(void)
{
// start serial port
Serial.begin(115200);
Serial.println("Dallas Temperature IC Control Library Demo");

// Start up the library
sensors.begin();
}

void presentation() {
// Send the sketch version information to the gateway and Controller
sendSketchInfo("Temperature Sensor", "1.1");
// Fetch the number of attached temperature sensors
numSensors = sensors.getDeviceCount();
// Present all sensors to controller
for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
present(i, S_TEMP);
}
}

void loop(void)
{
// call sensors.requestTemperatures() to issue a global temperature
// request to all devices on the bus
Serial.print(" Requesting temperatures...");
//sensors.requestTemperatures(); // Send the command to get temperatures
Serial.println("DONE");

Serial.print("Temperature for Device 1 is: ");
//Serial.print(sensors.getTempCByIndex(0)); // Why "byIndex"?
// You can have more than one IC on the same bus.
// 0 refers to the first IC on the wire

delay(1000);
