Hi all.
Very new to Node Red.
I have an MQTT node, with this output:
Preformatted text
{"topic":"flow-meter/heartbeat7","payload":"+112","qos":0,"retain":false,"_msgid":"rf6226f9.aug622"}
I want to use a change node to remove the text ""flow-meter/" from the object.
There is no JSONata option available. (please see image)
I would be grateful if anyone could let me know how to do this.
