MQTT in Node Configuration

General
1

Hello Folks,

I am trying to reduce costs using my AWS MQTT broker with Node Red.

One of the ways I am hoping to do this is by creating a function filter that only posts a payload if its different to the previous message?

Would this be done in the function node or is there a more embedded solution built into the MQTT nodes itself?

Thank you,

Yes - the RBE (Report By Exception) node does exactly this.

That great thank you, is there also a way to delay messages by 10 seconds each time one is submitted?

How about the delay node ?
