The initialisation process results the following error: Logger: homeassistant.components.sensor Source: components/saj/sensor.py:212 Integration: Sensor (documentation, issues) First occurred: 3:01:15 PM (2 occurrences) Last logged: 3:01:15 PM

Error adding entities for domain sensor with platform saj Error while setting up saj platform for sensor Traceback (most recent call last): File "/usr/src/homeassistant/homeassistant/helpers/entity_platform.py", line 382, in async_add_entities await asyncio.gather(*tasks) File "/usr/src/homeassistant/homeassistant/helpers/entity_platform.py", line 525, in _async_add_entity original_device_class=entity.device_class, File "/usr/src/homeassistant/homeassistant/components/saj/sensor.py", line 212, in device_class if self.unit_of_measurement == POWER_WATT: File "/usr/src/homeassistant/homeassistant/components/sensor/init.py", line 375, in unit_of_measurement self.device_class == DEVICE_CLASS_TEMPERATURE File "/usr/src/homeassistant/homeassistant/components/saj/sensor.py", line 212, in device_class if self.unit_of_measurement == POWER_WATT: File "/usr/src/homeassistant/homeassistant/components/sensor/init.py", line 375, in unit_of_measurement self.device_class == DEVICE_CLASS_TEMPERATURE ....

The root cause of the error: In sensor/init.py the SensorEntity.unit_of_measurement calls device_class property In saj/sensor.py in the SAJsensor(SensorEntity) class the deviuce_class calls unit_of_measurement
