**Is it possible?**  
**Yes it is** , and mostly because of the good eye of dceejay.  
So this is solved, althrough it could use some tweaking at the time.  
For now, I think it would not hurt to leave it here.

I was, but still am wondering about this and maybe my fantasies is going to wild here... but maybe.

I have an ESP8266 with a RGB controller on it. Nothing fancy.  
It has a webpage on it to control the RGB.

The RGB lamp works perfect with the websocket library on it.!

A websocket.js file is containing the JavaScript code  
 ![websocket_js_file](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/6/6f7e37d652991671993f16557a0003658dc82567.jpeg)  
Part of the code for sending after hitting a button.  
 ![send_example](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/b/be8d68495d4e76724c0d6b80f2c6ab562accee62.jpeg)

Is it possible to make something with Node-RED to control it?  
A button on the dashboard to set it on or off, or maybe even change the color!?  
I tryed the websocket node like this,  
 ![node-red_test1](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/b/beed648b7ebfa9440386682f5f59eaf06d6cdd36.jpeg)  
but, sure I am doing something wrong.  
I treid to follow a few examples on the web, maybe it's the language barrier, I can not find a way to set this up.  
Anybody an idea what I must do?  
Thanks in advance.

In your js code you have ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/7/7e9cd2f0e084fbec7be64fcea9a8c744d787c13a.png)  
and in your Node-RED example you have port 1881, and your web page just shows lol05.local - so which port is that ? so one or other isn't correct.

Good eye.  
In the sketch for the ESP8266 it creates a websocket on port 81.  
 ![websocket_port](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/a/a0ef4e94a626289cfe351951c33bcebcdbd933ad.jpeg)

One of the many examples (don't now the link any more) it was an advice to put 18 before the used port! I was wondering myself WHY? but it could not hurt to try.  
Sorry that I have left it there.  
At the same time I treid it without the 18 and it just works.  
Great. But stupid me that I didn't see that any more.  
Thanks man.

The main reason for not using ports below 1024 is that, on most servers, they require admin/root permission to handle the port. That is one of the reasons that Node-RED uses a port above 1024.

Doesn't apply of course on such a simplistic device as the ESP8266.
