>console.log(NodeMCU.D5)
D14

this is GPI14

My script

// Init ESP8266
var ESP8266 = require("ESP8266");
E.setClock(80);
var dht = require("DHT11").connect(D14); //NodeMCU D5

var dht2 = function(){
  dht.read(
    function(a){
      console.log(a);
  },10);

};

dht2();

{ 
"err": true, "checksumError": false,
"raw": "0100",
"temp": -1, "rh": -1

Pin is correct .. NodeMCU + DH11 work in Arduino.. but not working in ESPRUINO + DH11

ESPRUINO

result

{ 
"err": true, "checksumError": false,
"raw": "0100",
"temp": -1, "rh": -1 
}

But result Temp is -1 and RH is -1

echo(1);
// Init ESP8266
var ESP8266 = require("ESP8266");
ESP8266.setLog(2);
ESP8266.printLog();

//  console.log(e.time - e.lastTime);
//}, D14, {repeat: true, edge:"both"});

var dht2 = function(){
  dht.read(
    function(a){
      
      console.log("Temp is "+a.temp.toString()+" and RH is "+a.rh.toString());

  });
  return true;

Yes, need Http server run after WiFi getting IP address

// Init WiFi Networks
wifi.setHostname("my1");
wifi.connect("xxx", {password:"xxx"}, function(err){
  setTimeout(function(){
    console.log("connected? err=", err, "info=", wifi.getIP());
    // Init Your Http Server
    Init();
  },5000);

});
wifi.stopAP();
wifi.save();

NODEMCU LED() - ESPRUINO(D2)
NODEMCU A0 - ESPRUINO(D0)

But other Ping where i get diagram ?

I connect by this diagram to other my board D1 Wemos do not working in ESPRUINO

from this link https://hackaday.io/project/10498-caront­epass-open-access-control

Please help connect RC522 to NodeMCU v3 4M

My apologies i rising this problem... need start HTTP server after connecting to WiFi

var wifi = require("Wifi");
var dht = require("DHT22").connect(D0); // GPIO4
var lastDhtData ="none";

// Init WiFi Networks
wifi.setHostname("my1");
wifi.connect("XXX", {password:"XXX"}, function(err){
  console.log("connected? err=", err, "info=", wifi.getIP());
});
wifi.stopAP();
wifi.save();

function init() {
  initServer();
  //setInterval(function(){ console.log(process.memory()); }, 100000);
  //require("ESP8266").setLog(2);
}


function initServer() {
  var http = require("http");
  console.log("Initalizing server instance...");
  // Create Http Answer
  http.createServer(function(req, res){
    var request = url.parse(req.url, true);
    var action = request.query;
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.write('<html><head></head><body>');
    res.write(lastDhtData);
    res.end('</body></html>');
  }).listen(80);
}
// Get data from sensor every 1 minut
setInterval(function(){
  dht.read(function (a) {
    lastDhtData = a.temp.toString()+","+a.rh.toString();
  });
},60000);

// Send to server every 10 minut
setInterval(function(){
   postToServer(lastDhtData); 
},600000);

function postToServer(data){
  var options = {
    host: 'MAINLINK',
    port: '80',
    path:'/event',
    method:'POST',
    headers: {
      "Content-Type":"application/json",
      "Content-Length":data.length 
    }
  };

  require("http").request(options, function(res){
    var d = "";
    res.on('data', function(data) { d+= data; });
    res.on('close', function(data) {
      console.log("Closed: "+d);
    });
  }).end(data);
} 


E.on('init', function() { 
  init();
});

  console.log(e.time - e.lastTime);

Last question i read data from this sensor AM2301
and see ( Temp is -1 and RH is -1 )

All connected to GPIO D1.

Code from examples: dht.read(function (a) {console.log("Temp is "+a.temp.toString()+" and RH is "+a.rh.toString());});

My example programm:

var wifi = require("Wifi");
var dht = require("DHT22").connect(D1);

wifi.connect("xxx", {password:"xxx"}, function(err){
console.log("connected? err=", err, "info=", wifi.getIP());
});
wifi.stopAP();

wifi.save();

function readTemp(){
dht.read(function (a) {console.log("Temp is "+a.temp.toString()+" and RH is "+a.rh.toString());});
}

Thanks all .. this is my problem... i connect in my board D1 and Read from programm. D1.. But realy all pinout is other..

Example: ESPRUINO => D0 is my board => D3 -- GPIO0
