blynk-client defaults to connecting to blynk-cloud. Its really there as a first step to get your feet wet.

since you have your own server, take these six lines. save them as test.js. … create a v1 push button on your project screen.
and run it by doing `

sudo node test.js

var blynk = require('/usr/local/lib/node_modules/blynk-library');
var AUTH = '7ce8779c39674e168a72fbe30906ce27';
var tcp = new blynk.TcpClient(options={addr:"127.0.0.1", port:8080});
var blynk = new blynk.Blynk(AUTH, options = {connector :tcp});
var v1 = new blynk.VirtualPin(1);
v1.on('write', function(param) {console.log('V1:', param[0]);});

Then pickup where you left off on your reading/testing.

`

oops… there was an error in my code… may have to grab it again.

Hi Larry,

I try your code with modifications. the path for node_modules was not my path.

your code :

var blynk = require('/usr/local/lib/node_modules/blynk-library');

my code :

var blynk = require('/usr/lib/node_modules/blynk-library');

var AUTH = 'ef7a57a02ed4447ab2816e360e7f0ddd';

your code :  
```cpp
var tcp = new blynk.TcpClient(options={addr:"127.0.0.1", port:8080});  --> don't work ???

my code :

var tcp = new blynk.TcpClient(options={addr:"127.0.0.1", port:8081});

–> it work because I change my port

var blynk = new blynk.Blynk(AUTH, options = {connector :tcp});

var v1 = new blynk.VirtualPin(1);
v1.on('write', function(param) {console.log('V1:', param[0]);});

result

pi@pi-desktop:~/python$ sudo node test.js

Good job! I found that after the first time i got connected to my local server (just a few months back), my learning began. Hope you enjoy blynk as much as i do.
