This replaces the correction by specifying the sensor ID in WeatherSensorCfg.h. 

temp = ((sign) ? (temp_raw - 1000) : temp_raw) * 0.1f;

// Correction for Bresser 3-in-1 Professional Wind Gauge / Anemometer, PN 7002531
if (temp < -50.0) {
    temp = ((sign) ? -temp_raw : temp_raw) * 0.1f;
}

The sensor range (as far as provided in the manuals) is -40...+60°C, so there is no risk that the intermediate values overlap.
