Yes now it appears.
So the initial question is still there. I found this on reddit as an example how to do what i want to do (forward a message):
alias: 'test' trigger: platform: mqtt topic: home/buzzer1 payload: PRESSED action: service:mqtt.publish data: topic: home/test payload: "test"
This seems to do what i want to do. But where do i put it?
When i put it in configuration.yaml it shows errors. Same with automation.yaml
What is the right file to choose? Does this even do what i try to do?
