(As another user)
Did you load the program into the device and then in the left pane of the WebIDE type in
save();
?

@Aleksandrs, for what ever reason the conversation about After reboot HTTP do not working need reflash from WEB IDE is closed. It shows a closed pad lock next to the conversation title, and therefore nobody can respond to it. Furthermore, it has no explaining text about the steps you took to get to where you are.

Because @ClearMemory041063 wanted to respond, he 'recreated' the conversation. To include everything in this conversation, I'm replicating the code. @Aleksandrs, please provide context - board, wiring, etc,... and steps you took.

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();
});
/*
setWatch(function(e){
  console.log(e.time - e.lastTime);
}, D1, {repeat: true, edge:"both"});
*/

No problem, that's why we are all out here on the forum to help each other going and having fun... all this easy to use IoT: a new world! and especially with the easy and ready to use Espruino!

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();

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
