Friendly name for Custom component

Hi I have a bit of a silly question: did something change with the friendly_name property?
This custom component worked on my setup for a long long time https://raw.githubusercontent.com/KoljaWindeler/ESP8266_mqtt_pwm_pir_temp/master/HA/custom_components/sensor/mqtt_jkw.py

@property
def friendly_name(self):
“”“Return the fname of the sensor.”“”
return self._fname

I’ve just moved my installation to a new hardware, cloned my component but don’t get the friendly_name. Everything else works (even the icon) but not the name.
Any suggestions?
