</div>

this works for me:

```auto
{
   "brightness_pct" : payload.brightness,
   "hs_color" : payload.hue and payload.saturation ? [payload.hue, payload.saturation] 
}

```

Update:

```auto
{
   "brightness_pct" : payload.brightness,
   "hs_color" : payload.hue != null and payload.saturation != null ? [payload.hue, payload.saturation] 
}

```

This is actually better as it will work if hue or saturation = 0
