node-red-contrib-ttl

A Node-RED node for adding time to live (TTL) to messages and a second node for filtering messages which have timed out.

Install

Run the following command in the root directory of your Node-RED install

npm install node-red-contrib-ttl

Usage

ttl set node will add a time of death _tod parameter to any message that passes through it. The _tod parameter is a timestamp that is equal to the time the message arrived at the node plus the amount of time set in the TTL property of the node.

ttl check node will compare the _tod parameter of a message with the current time. If the current time is past the _tod the message will be considered dead and not be propegated.
