Here is an example that resets the rbe, you can reset by topic or if no topic specified, reset all topics. I often forget the rbe/filter node filters the payloads by topic to.
[{"id":"b2eb4dca.ed2c1","type":"inject","z":"c74669a0.6a34f8","name":"topic 1 value 1","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"1","payload":"1","payloadType":"num","x":200,"y":2400,"wires":[["460e158e.569cec"]]},{"id":"460e158e.569cec","type":"rbe","z":"c74669a0.6a34f8","name":"","func":"rbe","gap":"","start":"","inout":"out","property":"payload","x":410,"y":2400,"wires":[["9feea51b.32922"]]},{"id":"9feea51b.32922","type":"debug","z":"c74669a0.6a34f8","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":580,"y":2400,"wires":[]},{"id":"e59d5bf.098c2a8","type":"inject","z":"c74669a0.6a34f8","name":"topic 2 value 1","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"2","payload":"1","payloadType":"num","x":190,"y":2440,"wires":[["460e158e.569cec"]]},{"id":"222b099b.6f1806","type":"inject","z":"c74669a0.6a34f8","name":"reset all topics","props":[{"p":"reset","v":"any value you wish","vt":"str"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":140,"y":2540,"wires":[["460e158e.569cec"]]},{"id":"346fe934.fa43fe","type":"inject","z":"c74669a0.6a34f8","name":"reset topic 1","props":[{"p":"reset","v":"any value you wish","vt":"str"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"1","x":140,"y":2580,"wires":[["460e158e.569cec"]]}]
This was written on a 1.3 node-red, but as far as i am aware the reset is still there in V2
