      data:

I would like to choose the color for the effect

- service: mqtt.publish
  data_template:
  topic: wled/a1/api
  payload: '[FX=03] Wipe'

something like
rgb_command_topic: "red"

I think I solved it, I still have to do some tests

- service: mqtt.publish
  data_template:
  topic: wled/a1/api
  payload: '&R=255 &G=0 &B=0 &W=0'
