omg, i got two of these floating but then time is an issue here to.

What is still on my list is to try this one :

Would be a breeze to intergrate it in domoticz when it works..!

( hmmz works with neopixels 5v, so guess thats not one to try without modification of the code )

Script got a little bit big, but now i'm sure nothing strange will happen, because i implemented a few checks.

I also made a small page where a color can be picked and sent to the controller:
Spoiler: show

Code: Select all

<html>
<head>
<title>Colorpicker</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript">
jQuery(function($){
	var field1 = $('#hexcolorcode');
	$('#send').click(function(){
		if(!field1.val()){
			alert("Please enter a value");
			field1.focus();
			return;
		}
		jQuery.ajax({
			url: 'rgb.php',
			type: 'get',
			data: 'hex=' + field1.val()
		});
	});
});
</script>
</head>
<body>
<body>
<script type="text/javascript" src="jscolor/jscolor.js"></script>

Click here: <input class="color" id="hexcolorcode" value="66ff00">	
<input type="button" value="Submit" id="send">
</body>
</body>
</html>
It uses 'jscolor' colorpicker: http://jscolor.com/try.php

For scripting: this commandline command also works:

Code: Select all

echo -e '\xfb\xeb\xf0\x00\xff\x00\x00\x79\x97\x9d\x00' | nc -u -w1 192.168.4.23 30977
Might be useful for a Lua-script later on.
Very interesting!!
Great work!

I have some self built RGB led controllers on esp8266 wich listen on UDP.
I can reprogram then to only respond on the color-hex parameter in an UDP packet.
By sending to the broadcast IP i can switch all the esp's at the same time
They are used for X-mas lighting led-strips on the frontwall of the house

So all i have to do is strip the scripts from the parts i dont need

But wondering, do i have to put the color-picker html page as the action-on on the dashboad ?
Do i understand correctly that the color-picker script calls the php-script ?

Hi GerardM,

You can call the PHP-script like this: rgb.php?hex=ff8d00

But you can also do it directly from commandline with the 'nc' command. This saves you from having a webserver needed etc. But for the commandline part, you need to send the HEX-command, which is a bit more difficult.

The php script will most def work.
I am going to reprogram the esp led controlers so they understand the hex code
But i was very interested how to use the color-picker html script in domoticz

So i can pick a color and then send it to all the led controlers.

Is it possible to do that from the dashboard ? Or do i need a frontpage ?
Which is a next project when the x-mas lights work

The link between the controller and Domoticz dashboard, is something i haven't done (yet?).
Main blocking point is that a virtual RGB-device doesn't spit out his current color, so i have no idea how to get that information passed on to the controller.
Second is that it probably would cost quite some time, and i don't change the color very often so it will be of little use for me.

Btw, i now have also gathered the information from this topic and put it on my Bitbucket account here.

Thnx
Any idea why nc wont sent an UDP packet to the broadcast address?

The ledcontrollers get their address from DHCP
When i use nc for a single node, it works (192.168.1.163)
When i want to send a command to all of them (192.168.1.255) it doesnt work

I checked with packetsender on windows and i dont see an incoming packet

For the rest, great help !

I suppose the 192.169.1.255 is a typo ;) ?

Normally the broadcast address is .255 i thought, so i don't know why it doesn't work. I only have one H801 box, so i can't test it unfortunately.

Yes, typo :)
Fixed

Ill guess i have to address then ony by one.
The delay this creates isnt even annoying in the chtrismaslights sequences...

Maybe you can sniff the original app to see how that works. I thought it also send the commands to the broadcast IP. But it's a while ago i did the sniffing, so don't know anymore.

There isnt an original app
I made the led controllers myself

So i know where they listen and on what port

At the moment they listen for commands like RRR for full red, BBB for full blue etc..
B2R for fade from blue to red etc

Ill think ill keep it that way and change the script with nc

Found it...
nc cant do that by design

Have you test it with quinled ?

Does somebody know how to get the device to connect to an existing access point without using the android app?

I found on github an ESP firmware who turn it on a Milight bridge + ledstrip controller for pwm led strip.

I test everything looks OK

https://github.com/frizzby/esp8266-rgb-led

I'm starting a conversion for Ws2812b led strip : https://github.com/deennoo/ESP8266-ws2812b/tree/nodemcu

This firmware looks interesting: https://eryk.io/2015/10/esp8266-based-w ... ller-h801/
Using a simple http call to the device on http://192.168.0.xx/rgb/ff0000 it is possible to send RGB values in HEX and let the color of the leds change to this color.
It seems this: https://github.com/jeffeb3/esp8266_lights is based on the code from eryk.io, but i don't see actually what has changed in comparision with the original code form eryk.io?

Now that communication protocole is done with original FW, isn't possible to include it as a "normal" hardware on Domoticz, using Milight or Philips Hue as exemple ?

A french homeautomation software juste release a plugin for it, to use it with the original Fw...
