• While you upload the code, some initializations happen which do not when you run the saved state after those.

    Try to put the 'connectsinto anonInit()` function and it should work:

    var dht = null, dhtMod = require("DHT11");
    var WebSocket = require("ws");
    var wifi = require("Wifi");
    var WIFI_NAME = "MY WIFI NAME";
    var WIFI_OPTIONS = { password : "MY WIFI PASSWORD" };
    
    function onInit() {
    
    dht = dhtMod.connect(D4);
    
    wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
      if (err) {
        console.log("Connection error: "+err);
        return;
      }
      console.log("Connected!");
      
      var host = "MY IP";
      var ws = new WebSocket(host,
        {
          path: '/',
          port: 80, // default is 80
          protocol : "echo-protocol", // websocket protocol name (default is none)
          protocolVersion: 13, // websocket protocol version, default is 13
          origin: 'Espruino',
          keepAlive: 600,
    (default is none)
        }
      );
      ws.on('open', function() {
        console.log("Connected to server");
        setInterval(function(){
          dht.read(function (a) {
            ws.send('{"temp":"'+a.temp.toString()+'"­,"rh":"'+a.rh.toString()+'"}');
          });
        },10000);
      });
    });
    
    } // /onInit()
    

    If you now 'just' upload, nothing happens...

    To get it running, enter onInit() in the console - left side - of the Espruino IDE.

    When the code works as you expect, upload again, and then enter save() in the console - left side - of the Espruino IDE. This will save the code and run the onInit() and you should be fine. Any power cycle after that will run onInit() and do what you expect.

  • Ah I see, everything works now as it should. Thank you very much!

    Do you recommend I always use onInit when I want to save code?
