Service allows to set mqtt proxy from wirenboard rule script

Install

Please connect your device to the internet

Install NodeJS, if it is not yet

curl -sL https://deb.nodesource.com/setup_12.x | bash -
apt-get install -y nodejs git make g++ gcc build-essential

Install this packet to global space

npm i -g wirenboard-mqtt-proxy

Start the service

wirenboard-mqtt-proxy start

To enable autorun on boot use it

wirenboard-mqtt-proxy enable

After that you will see mqtt proxy device inside wirenboard UI

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
