Node Red dimming lights

Third party integrations Node-RED
1

Hello,

Im trying to simplify my node-red flows a bit using templates after input from switches, but cant figure out how to not merge the data sent to the call service node properly.
This works sending as a payload

{
    "service": "turn_on",
    "data":
    {
        "brightness_step": 255,
        "transition": 7
    }
}

However, trying to stop dimming by sending this, all it does is setting transition to 0, dimming all the way to 100% immediatly. Is it possible to overwrite this value?

{
    "service": "turn_on",
    "data":
    {
          "brightness_step": 0,
         "transition": 0
    }
}

Probably you shouldn’t send a command “go to full brightness in 7 seconds” and stop this command somewhere down the line. That second snippet is off in 0 seconds, so exactly what is does.

{
    "service": "turn_on",
    "data":
    {
          "brightness_step": 20,
         "transition": 1 //1 or 0.5 or whatever timespan
    }
}

And send new msg to Trigger template node after X (milli)seconds.
