Collecting multiple values - cflurin/node-red-contrib-dsm GitHub Wiki

Often you have to collect multiple values before you can control devices or generally go ahead with the flow. Although node-red offers several ways to achieve this task using the dsm node can be an alternativ solution.

Configuration

{
    "currentState": "empty",
    "states": {
        "empty": {
            "setData": "filling"
        },
        "filling": {
            "setData": "filling",
            "getData": "empty"
        }
    },
    "data": {
        "indoor": 0,
        "outdoor": 0
    },
    "methods": {
        "setData": "sm.data[msg.payload.name]=msg.payload.value;output=false;",
        "getData": "msg.payload=RED.util.cloneMessage(sm.data);sm.data.indoor=0;sm.data.outdoor=0;output=true;"
    }
}
