Is it possible to control brightness?

[crixyd]

I own a 2022 the frame (QA65LS03BAWXXY) and am dissatisfied with the light sensor for brightness control, and was hoping to use a lux sensor and some automations to override the brightness. Unfortunately I can't find any mention of brightness controls via the WS API. Samsungctl supports brightness control in legacy mode, but it doesn't work on the frame. Is there a way to set brightness using this library that I am missing? Or perhaps a way to add support?

I just added the following functions to samsungtvws/art.py and tested on my 55" (2019) frame (model QN55LS03RAFXZA) while in art mode and it works.

    def get_brightness(self):
        response = self._send_art_request(
            {"request": "get_brightness"},
            wait_for_event=D2D_SERVICE_MESSAGE_EVENT,
        )   
        assert response
        return json.loads(response["data"])

    def set_brightness(self, value):
        self._send_art_request(
            {   
                "request": "set_brightness",
                "value": value,
            }   
        )

You could tweak the get_brightness function to return just the brightness value but I return everything since the response also includes the min and max values for the setting which could be useful for integrating into a UI. Here's sample output from my frame.
