Hi  
I don´t know where to start looking for answer. Maybe some one can point me in the right direction.

I´m trying to start a playlist on my Falcon F16V4 controller.  
I have this information

**MQTT Settings**

- MQTT events will be published to “falcon/player/FPP/” with playlist events being in the “playlist” subtopic.

- **CA file** is the full path to the signer certificate. Only needed if using mqtts server that is self signed.

- **Publish Frequence** should be zero (disabled) or the number of seconds between periodic mqtt publish events

- FPP will respond to certain events:

|Topic|  
| — | — |  
falcon/player/FPP/set/playlist/${PLAYLISTNAME}/start

|Action|  
| — | — |  
Starts the playlist (optional payload can be index of item to start with)

This is my latest try. Anyone know howto split into message and topic?  
Do I need to add some characters

The message usually is the last bit of the topic  
send to topic:  
falcon/player/FPP/set/playlist/Halloween

message:  
start

Not sure if they want the playlist name to be in the `${ }` part, just try the two different playlistname formats

Thanks for some good ideas, but sadly they did not work.  
After searching some more I find an example from HA.

If someone else is running into a similar problem, here is my solution

Message: HALLOWEEN (Name of my playlist)  
Topic: falcon/player/FPP/playlist/name/set

This starts the playlist and plays it onetime

Good to hear.  
Still it’s odd the topic is a shuffled version from the example by Falcon 😏
