var stromRequest = new XMLHttpRequest();
          var requestURL = 'http://192.168.178.44/cm?cmnd=var1';
          stromRequest.onreadystatechange = function () {
            if (stromRequest.readyState === XMLHttpRequest.DONE) {
              if(stromRequest.status === 200) {
                var json_parse = JSON.parse(stromRequest.responseText).Var1
                var stromverbrauch = Number(json_parse * 0.30)//.toFixed(2);
                var verbrauch = stromverbrauch.toFixed(2);

this is my request and the error:

@fischi87

so I assume the code snippet is from the module.js (not from node_helper.js). The url with IP 192.168.178.44 is pointing to another device in your network and is therefore different to the IP where mm is running?

If mm has the same IP you could try localhost instead, if the IP’s are different you can try this:

var requestURL = location.protocol + "//" + location.host + "/cors?url=http://192.168.178.44/cm?cmnd=var1";

The 2. option with the cors url works only with the develop branch of mm (will be in the next official relase coming 1. April).

thats right, its from the module.js. i read i can fix this issue with the node_helper.js but i dont know how to write the code down in the node_helper.js to get the result from my url.

i will try ur answer later.

i know how to write code in the node_helper.js form the request?

thanks
