Try this.

var myCommand = "GET /data_request?id=lu_action&output_format=xml&DeviceNum=3&serviceId=urn:upnp-org:serviceId:SwitchPower1&action=SetTarget&newTargetValue=1 HTTP 1.0\r\n
host: 192.168.0.151\r\n
connection: close\r\n\r\n\r\n";

// todo - send myCommand

Hi Lyndel,

I'm struggling with this. I have added the port number after the IP address and pasted the following to a button, but its not turning the light on.

function send lightCommand {
var myCommand2 = "GET /data_request?id=lu_action&output_format=xml&DeviceNum=3&serviceId=urn:upnp-org:serviceId:SwitchPower1&action=SetTarget&newTargetValue=1 HTTP 1.0\r\n
host: 192.168.0.151:3480\r\n
connection: close\r\n\r\n\r\n";}

send lightCommand

I have also tried posting the code in the Actions Properties then calling it from a button press with

send lightCommand

Is the issue with how I am calling the function or could it be the http request isn't quit right?

Thanks

Steve

Sorry you are struggling. There are HTTP examples in the ProntoScript Dev Guide that illustrate alot of the above. Also, there are posts here in this forum that discuss usage of the Host HTTP Request Header as well as the Connection HTTP Request Header. Try a search here for HTTP 1.0 and you will likely find some other examples. ProntoScript is fairly easy. It is getting the strings right that you exchange with other equipment that can be difficult.

You don't put the port on the host line. You put that in your call to socket.connect.


Put a try/catch block around code in your functions and if an error is caught, log it using System.print.

This will tell you whether you have a syntax error or the request is not right.

Several years back I did a writeup on use of try/catch for debugging. Might want to try a search for that thread as well.

Ok will do. Thanks again.

Steve

In your string, change the occurrences of ':' in the URL parameters to %3A

function send lightCommand {
var myCommand2 = "GET /data_request?id=lu_action&output_format=xml&DeviceNum=3&serviceId=urn%3Aupnp-org%3AserviceId%3ASwitchPower1&action=SetTarget&newTargetValue=1 HTTP 1.0\r\n
Host: 192.168.0.151\r\n
Connection: close\r\n\r\n\r\n";}

This is what is meant by URL encoding. Also note that I removed the : from the Host and also changed the casing on Host and Connection.

Lyndel,

I tried your updated code but still no luck with it. However I took your advise and searched for HTTP 1.0. I experimented by tweaking some examples and success this code seems to work -

////////////////////////////////////////////
//
var socket = new TCPSocket(false);
socket.onConnect = function()
{
socket.write("GET /data_request?id=lu_action&output_format=xml&DeviceNum=3&serviceId=urn:upnp-org:serviceId:SwitchPower1&action=SetTarget&newTargetValue=1 HTTP/1.1\r\n\r\n")
socket.close();
};
socket.onClose = function()
{
};
socket.onIOError = function(e)
{
label = "Error: " + e;
};
socket.connect('192.168.0.151',3480);
//
//
/////////////////////////////////////////////

Moving on to my next part, are button sliders supported? It would be great if I could have a button slider that could dim a light. I have done a search but can't seem to find anything here. I gues I maybe out of luck?

Thanks for all your help.

Steve

You can have an example of a slider from going to www.the-gordons.net as Barry published one a few years back that has 20 buttons and does a 5% increment.

This technique was done before onMove was added to ProntoScript. Also, there was a color picker example that someone posted here a while back. Might want to have a look at that script.

I gave up sometime ago trying to get a slider working with http commands to control my lighting, however I decided to try and give it another go. I downloaded 'Rick's Slider Control'

[Link: files.remotecentral.com]

Looking at Rick’s code there is an option to change the slider from a vertical slider to horizontal slider by changing dimmer orientation variable to a ‘0’ from the default ‘1’. I also rotated the images to horizontal and the slider demo seems to work ok apart from it not remembering its position when I exit the page and re-enter. If I change it back to vertical it remembers just fine. I must be missing something in the code to enable this position memory but I'm not sure what I am looking for.

For information, I want to use a dimmer scale of 0-100. In my copy of the code I changed all the ‘15’s in the code below to ‘100’

Any help would be much appreciated.

Many thanks

Steve

You mention orientation but I am not seeing such a variable in the code above.

See the comments in the code about the use of System.setGlobal and System.getGlobal. Maybe you forgot to code an onExit handler for your page to set the value into the global?

I think you are only showing us 1/3 of the code. ;-) Especially since the code you posted has comments at the top that talk about page scripts, etc...

Hi Lyndel,

As always you are correct. my issue was in the page properties. I had the code detailed below in the properties of the page but I hadn't changed the ),1); to the necessary horizontal requirement of ),0);

dslider(widget("KNOB1"),widget("SG1"),widget("SL1"),page("DCP6"),1);
dslider(widget("KNOB2"),widget("SG2"),widget("SL2"),page("DCP8"),1);
dslider(widget("KNOB3"),widget("SG3"),widget("SL3"),page("DCP4"),1);
dslider(widget("KNOB4"),widget("SG4"),widget("SL4"),page("DCP5"),1);

I can confirm this is now remembering the state on re-entry. Thank you for pointing me in the right direction.

My last problem is to work out how I would parse the slider light level into the code below on release. In the code sample snipet newLoadlevelTarget=25

25 is the light level. With DeviceNum=3 being as it looks i.e. light ID number 3.

Any help would be much appreciated.

Many thanks

Steve
