node-red-contrib-dedup

Node-RED node that removes duplicate messages from a flow based on a single message property value.

Each incomming message is checked to see if it contains the property and if it does the value of the property is compared against any previous messages containing the same property. If the node has received a duplicate message within the expiry time the message is dropped, otherwise the message is passed to the output.
