Need help please, http /node-red

Hello everyone, first sorry for my bad english. I need your advice please.
I wanted to use the homey http app to send a command to Node-red, which would then make my TV mount (Vogels motion mount) move. How does that have to look like under Homey / Nodered? Node-red runs on a raspberry pi 4b. Can maybe anybody show the command in homey and nodered. Sorry if it’s a stupid question, this is completly new for me. Thanks

The homey http app is 4 years old and only the developer of it have the code so don’t use it.
