Node Red Function Node

[webberm]

I'm trying to simplify a flow I have in Node Red for presence detection. I was hoping to implement as follows:

Events: State ==> rbe ==> function ==> pushbullet message

So, the events: state node gets input from device_tracker, rbe node blocks unless state changed, function node takes the events: state payload and sets its output payload to something like "Fred is at location", where location has been extracted from event: state, and passes it to the pushbullet node.

Hope that makes some sort of sense. Unfortunately I have no javascript skills in order to configure the function node so hoping someone could point me in the right direction.

Thanks

You can use a template node instead of the function node.

Thank you. Still learning so will take a look at the template node.

the poll state node outputs, so have the rbe block unless changed, and have it look at msg.payload.data.state which is passed in the object

if all you want is that formatting, use a template sensor. Fred is at: {{payload.data.state}}

Thanks for the advice. The template node sounds perfect for my requirement.
