node-red-contrib-timeframerlt (timeframe rate limit trigger)
Node-RED A Trigger and Rate Limit Node to pass messages if user count has been met within a defined user time frame.
Table of Contents
Install
Run the following command in your Node-RED user directory - typically ~/.node-red:
npm install node-red-contrib-timeframerlt
Usage
A Trigger and Rate Limit Node to pass messages if user count has been met within a defined user time frame. Just insert the node in between two others. Then the ammount of messages received in a certain time frame to trigger can be limited by different parameter selections.
Timeframe
Amount of time given before message trigger event is reset.
For example: setting the node to 10 seconds means, that you have ten seconds to reach enough messages to trigger one message to be forwarded.
Count Persistent
Ammount of messages needed to trigger before one message is passed through. Persistent, If triggered the count is reset and it can be triggered again.
For example: setting the node to a count of 5 means, that five messages are needed within the specified timeframe before one message will be forwarded.
Count Terminable
Will only pass through a single message, ONCE! Hence Terminable. When the ammount of messages needed active the trigger is reached. The trigger can be reset to send message when conditions are met again with msg.reset.
For example: setting the node to a count of 5 means, that five messages are needed within the specified timeframe before one message will be forwarded Once, One time, and never again, even if conditions are met again.

Thanks to SunValleyFoods for being a buisness that supports opensource. They needed this node for a tempsensor monitoring and automation project for their freezers and cooers.
Thanks to allot of code written by Daniel 'Eisbehr' Kern and his node-red-contrib-throttle. I based and copied allot of code off his work as his node did not quite do what i needed.
