sensor AssertionError with 2022.4

Hello I’m trying the last beta and I got an error. I added two lines to /usr/src/homeassistant/homeassistant/components/sensor/__init__.py to know which integration raise this error

            _LOGGER.warning(self.name)
            _LOGGER.warning(native_unit_of_measurement)

logs:

Thank you

I had the same issue but I had to keep the _attr_device_class to the existing “DEVICE_CLASS_TEMPERATURE”, it didn’t like changing it to SensorDeviceClass.TEMPERATURE. I’ve got v0.16.2 installed through HACS and I was editing directly in the custom_components/dyson_local/ folder using Studio Code Server. Also like everything HACS, had to restart HA after making changes for them to show up.

As for the switches and other sensors, I was able to get them working by editing sensor.py and switch.py using this change from the Alexa Media Player.

I basically added from homeassistant.helpers.entity import EntityCategory to the top sections of the two files and then changed any instance of ENTITY_CATEGORY_DIAGNOSTIC to EntityCategory.DIAGNOSTIC and instances of ENTITY_CATEGORY_CONFIG to EntityCategory.CONFIG.

Don’t know how to do a pull request, but hopefully this might help.

The current brach - unreleased - already has these fixes. I think for users already upgraded to 2022.04 it makes sense that @shenxn creates a new release which includes my PR. I don’t have any Dyson errors / warnings in my HA with this.

Glad to see I’m not the only one, so many entries that dont work that I use a lot (mostly the night mode toggle lol).
