Hi everyone
I have built a flow in node red to play a message via my Google Home when I arrive home.
I have a function node which prepares the message and passes it through in msg.payload then a call service node to call the speak service using Piper to generate the audio.
Here’s a simplified version of the flow. The real function has logic in it to create a custom message depending on a number of entities and global variables, but for simplicity I am just passing basic text in this example.
When I run this, the Google Home just says payload rather than the payload content which is Welcome home.
Any ideas what I’m doing wrong here?
