Delayed message

A single node approach to store a delay (local) and to send a msg to the output after the delay.

Configuration

{
    "data": {
        "delay": 3000
    },
    "methods": {
        "setDelay": "sm.data.delay = msg.payload;",
        "default": {
            "name": "timer",
            "param": "delay",
            "do": [
                "node.status({fill:'blue', shape:'ring', text:msg.payload});",
                "node.send(msg);"
            ]
        },
        "status": {
            "fill": "blue",
            "shape": "dot",
            "text": {
                "get": "sm.data.delay"
            }
        }
