What can be set via state.set()?

[wsw70]

I am creating ad-hoc entities via state.set(). An example would be:

state.set("aaa.something", "wazaa", new_attributes={
            "icon": "mdi:web", 
            "name": f"monitoring something",
            "object_id": "hksdjlhfsdkjfhqdskjhfnbd",
            "unique_id": "kjljlkjlkjlkjlkj"
            })

The entity is created

• something is the name
• aaa.something is the entity
• wazaa is the value
• mdi:web is the icon

But:

• "name": f"monitoring something", is not taken into account → I can live with that
• there is no unique ID fo that entity, despite an attempt to push one via the two last entries

This means the status can't be edited via the UI, and I would like to know why:

• is this because the entity ID cannot be set that way
• or weather I am setting it wrong
• or something else?

Note: I think that this question is not really related to pyscript, I will ask it on the global forum as well. It is here just in case :))

EDIT: I found an old question of mine where I mentioned that I can create an almost working entity via MQTT discovery:

topic=f'homeassistant/binary_sensor/{endpoint_name}/config',
        payload = json.dumps({
            "icon": "mdi:web", 
            "name": f"monitoring {endpoint_name}",
            "state_topic": f'homeassistant/binary_sensor/{endpoint_name}/state',
            "object_id": endpoint_name,
            "unique_id": endpoint_name
            }),
        retain=False

I thought initially that setting the state would not be able to set anything else than, well, the state (and creation of the entity). But somehow the icon can be set as well via the attributes.
