Cool! Now we can use proxy from wirenboard rules. Lets start from simple script, where we will get current temperature from ebus daemon using topic ebusd/370/DisplayedRoomTemp

Due to connect value we can detect when service started after device reboot, so since proxy started lets add necessary topic. Best way to do it - using JSON format task

{
  "task": "add",
  "from": "ebusd/370/DisplayedRoomTemp",
  "to": "/devices/test/controls/t_current"
}

Result rule: test.js

//  created virtual device called "Test"  //
defineVirtualDevice("test", {
  title: "Test",
  cells: {
    t_current:     { type: "temperature",     value: 0 },
    status:     { type: "text",     value: "NOT CONNECTED", forceDefault: true},
  }
});

//  check proxy started  //
setInterval(function(){
  //  wait service started  //
  if (dev["mqtt-proxy"]["connected"] !== 1) return;

  //  set topics  //
  if (dev["test"]["status"] !== "CONNECTED") {
    dev["test"]["status"] = "CONNECTED";
    log("Test: Connected to proxy");

    dev["mqtt-proxy"]["config"] = '{ "task": "add", "from": "ebusd/370/DisplayedRoomTemp", "to": "/devices/test/controls/t_current" }';
  }
}, 1000);

When proxy will be connected, test device will set config and will receive temperature data
