Send brightness to hue light with hue magic?

I’m trying to setup a simple hue light and turn it on with a set brightness of 20%. What is the json format I need to setup in the light node or send to it? i have tried everything and all it does it turn on the light at the previous set value.

Well I ditched the Hue Magic node and just used a HA call service node. Works perfect.

With a JSON:

{
    "entity_id": "light.stove_light",
    "brightness_pct": 50
}
