Hello, Been using Node-RED for a week or so now. And have a question about the delay node. A couple of days ago I started creating a flow where I needed to limit the amount of messages passed on to another node. Found the delay node, and set it to "Rate Limit" and 1 messages per hour. And I do bel…

The code hasn't changed its operation. In per topic modes the timer starts on deploy... so say it was set for 30 seconds - if the first message actually turns up at 29 seconds then it will come out 1 second later when the timer ticks. In all topics mode then indeed it works as you suggest as the tim…

How are you deploying ? Full deploy ? or just modified flows or nodes ?

In that case I'm a a loss - as it should always send the first message. Can you share the relevant part of your flow here in case there is something we can replicate ?

Lets hope I'm doing this right... I am a total noob on Node-RED. Here is my test flow: [{"id":"978372e8.76582","type":"tab","label":"Testing","disabled":false,"info":""},{"id":"8072285a.f93178","type":"inject","z":"978372e8.76582","name":"","topic":"test","payload":"","payloadType":"date","repeat"…

Indeed, I could reproduce in my system (windows10, Node-RED V0.20.0 beta3), however, the first msg is not forwarded only when action is configured as "For each msg.topic". It will not happen when the config is "All messages"

Same here I see now. If I choose "All messages" instead of "For each msg.topic" then it is working.

Aha - actually now I think about it - ... it IS working as designed... (possibly) The idea being that in per topic mode there are two sub modes... 1) where you send each topic that arrives in turn... I call this a topic based fair queue - each topic gets a turn in the queue - and any more recent d…

But I am 99% certain that when I tried it a couple of days ago, it did pass the first message per topic and dropped the rest, until the time has passed (I do have the "drop intermediate messages") checked, or it is not possible to unselect it). And if I read the issue on GitHub from 2014 that I ref…

Thank you for the explanation. Now I have a better understanding of what is going on. And I now know what has changed since my first tests that made me think something was not right. At first I had only one node sending messages through the delay node, and most probably had it set to "All messages"…
