Hi
Thanks for your help.
There is a good use case for including the RELEASED events into this logic, as there are some situations where an action is needed when the button / input is pressed and another when it is released.
For example…
Start on Press
Stop on Release
What I am trying to create is a Generic Solution that I can save in a library and adapt for real world flows.
It looks like I can use either solution, but I can’t use both in the same IF Function.
These are the solutions I have running.
The IF statement is this
var event = msg.payload.event;
var channel = msg.payload.channel;
var newMsg = { payload: msg.payload.event };
var button = "velbus:vmbgp2:c5053467:24:input#CH1"
if (channel === button ) {
if (event === "PRESSED") {
return [newMsg, null, null];
}
if (event === "LONG_PRESSED") {
return [null, newMsg, null];
}
if (event === "RELEASED") {
return [null, null, newMsg];
}
}
return null;
With the nodes being configured like this

The version with the IF Function to filter the button and a Switch to filter the button states, then with some triggers to reset the Debugs so that new events can be seen in the Flow, looks like this
The IF Function is simply this
var channel = msg.payload.channel;
var button = "velbus:vmbgp2:c5053467:24:input#CH1";
var newMsg = { payload: msg.payload.event };
if (channel === button) {
return [newMsg];
}
return null;
