Hello Community, Two quick questions: Is there any ways to block the first message coming to the flow, and then let the following to pass ? any chance to reset the RBE function after 1h or 2h after the first message has been blocked ? Thank you very much for your preciouse help.

Hi yes - the info panel on the right for the RBE node tells you about msg.reset. And the node options include - ignore initial value. (ie block it)

Hi dceejay, I have tried the RBE - Ignore initial value, but I cannot find a good result using it. According to my flow, each time two buy messages are coming, the RBE blocks both.

How do you determine what the "first" message is ?
ie. what is the trigger to block it ? If you restart node-red, is there a "first" message or does it continue ?

Your RBE flow won't work, you will have to inject msg.reset into the RBE node.
