sensor AssertionError with 2022.4

[Aohzan]

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 have the same and change the code to:

            assert unit_of_measurement
            _LOGGER.warning("Entity %s",self.entity_id)
            assert native_unit_of_measurement

This returns: 2022-04-06 10:48:37 WARNING (MainThread) [homeassistant.components.sensor] Entity sensor.dyson_temperature

If I disable that entity the error goes away

[jasperslits]

Adding

    native_unit_of_measurement = TEMP_CELSIUS

I'll make a PR later but this is what sensor.py should be changed to in Dyson_local:

class DysonTemperatureSensor(DysonSensorEnvironmental):
    """Dyson temperature sensor."""

    _SENSOR_TYPE = "temperature"
    _SENSOR_NAME = "Temperature"
    _attr_device_class = SensorDeviceClass.TEMPERATURE
    native_unit_of_measurement = TEMP_CELSIUS

Ah that explains some things! :D

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).

Probably there might be more in need of a replacement with unit of measurement but this was the only one - for now - that kept spamming the logs.

I actually used the latest git main branch of the component as it contains quite a few other changes compared to the latest release from last year. My changes were based on the current branch.

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.

PR merged and new release made, sorry for my absence these days I am really sick :S

Tell me if it fixes everything :)

Thanks and get well soon! Now the part that needed to be cleaned up was the libdyson reference as it looks that also needed to be bumped as current code depended on an unreleased version?

That's this commit: https://github.com/shenxn/ha-dyson/commit/e742bae807758bc8a3d109ae30da602c5951ad01
