Trying to get RFX433 Devices working

[baptist]

For me HG does everything with the slight exception of RFX433. (I have a whole load of various LightwaveRF switches)

First of all I managed to adapt the 'Serial Port I/O Test' program and managed to send the correct byte data to turn on some light switches on / off. Since then, for the last few days I've been trying to adapt different programs to create modules. However with my limited C# skills, really struggling..

This is where I got to, but still getting errors

Code: [Select]

var moduleDomain = "HomeGenie.RFX";
var portname = "/dev/ttyUSB0";

SerialPort
  .WithName( portname )
  .Connect( 38400 ); // change baud rate if needed

while (Program.IsEnabled)
 
//
{ 
   
    When.WebServiceCallReceived("HomeGenie.RFX", ( args ) =>
    {
        string[] reqs = ((string)args).Split('/');
        var res = "{ 'ResponseValue' : 'ERROR' }";
   
        try
        {
            string command = reqs[2];
            var module = Modules.InDomain("HomeGenie.RFX").WithAddress("1").Get();
    switch(command)
    {
         
         
              case "Control.On":
              byte[] message = { 0x0A, 0x14, 0x00, 0x02, 0xF4, 0x5F, 0x59, 0x01, 0x01, 0x00, 0x00 };
                Program.RaiseEvent(module, "Status.Level", "1", "RFX");
                res = "{ 'ResponseValue' : 'OK' }";
                break;
                           
              case "Control.Off":
              byte[] message2 = { 0x0A, 0x14, 0x00, 0x02, 0xF4, 0x5F, 0x59, 0x00, 0x01, 0x00, 0x00 };
                Program.RaiseEvent(module, "Status.Level", "0", "RFX");
                res = "{ 'ResponseValue' : 'OK' }";
                break;
         
      }
}
catch (Exception ex)
{
    res = ex.Message + " " + ex.StackTrace;
}
// unable to process request
return res;
});
//
Program.GoBackground();
Any advice would be much appreciated

Hi baptist,

to access virtual modules from your program you've to create them first. See this:

http://www.homegenie.it/docs/automation_advanced.php

read the paragraph about virtual modules.

Anyway I was in the will of porting this https://github.com/opensourceautomation/Open-Source-Automation/blob/master/Plugins/OSAE.RFXCOM/OSAE.RFXCOM.cs to a MIG Interface class.
HG r408 was refactored to facilitate the process of adding interfaces to mig/homegenie, so it might be the right moment of doing this since you have hardware to test.
Still I'm looking for some users with Insteon hardware... do you know any? =)

Cheers,
g.

[baptist]

Thanks Gene, I'll try to create a Virtual module.
Sorry I don't have access to INSTEON  devices.
I only have several LightwaveRF wall dimmers / mains sockets and a Lightwave PIR.
Also hard wired PIR's door contacts to MCP23017's > HG

[baptist]

Hi Gene .. Sorry but I'm still getting errors. Can you let me know where I.m going wrong, Many Thanks

Code: [Select]

Program.AddVirtualModules("Components.RFX", "Switch", "homegenie/generic/RFX", 1, 1);

var portname = "/dev/ttyUSB0";
SerialPort
  .WithName( portname )
  .Connect( 38400 );   
    When.WebServiceCallReceived("HomeGenie.RFX", ( args ) =>
    {
        string[] reqs = ((string)args).Split('/');
        var res = "{ 'ResponseValue' : 'ERROR' }";
   
        try
        {
            string command = reqs[2];
            var module = Modules.InDomain("HomeGenie.RFX").WithAddress("1").Get();
    switch(command)
    {
         
         
              case "Control.On":
              byte[] message = { 0x0A, 0x14, 0x00, 0x02, 0xF4, 0x5F, 0x59, 0x01, 0x01, 0x00, 0x00 };
                SerialPort.SendMessage(message);
               Program.RaiseEvent(module, "Status.Level", "1", "RFX");
                res = "{ 'ResponseValue' : 'OK' }";
                break;
                           
              case "Control.Off":
              byte[] message2 = { 0x0A, 0x14, 0x00, 0x02, 0xF4, 0x5F, 0x59, 0x00, 0x01, 0x00, 0x00 };
                 SerialPort.SendMessage(message2);
                Program.RaiseEvent(module, "Status.Level", "0", "RFX");
                res = "{ 'ResponseValue' : 'OK' }";
                break;
         
      }
}
catch (Exception ex)
{
    res = ex.Message + " " + ex.StackTrace;
}
// unable to process request
return res;
});
//
Program.GoBackground();

The program saves without errors, (shows a green symbol )however when I tried to add the switch into the group, I get the question mark error icon.. Any advice much appreciated.

Hi baptist,

I suppose the widget specified is wrong.
Try changing "homegenie/generic/RFX" with "homegenie/generic/switch", for a list of existing widgets see:

http://www.homegenie.it/docs/automation_widgets.php

cheers,
g.

[baptist]

Thanks Gene, I now have the widget. But when I operate Control.On I don't see any activity on the RFX device. (When I modify the program 'Serial Port I/O Test' with the correct byte information it works)

Code: [Select]

Program.AddVirtualModules("Components.RFX", "Switch", "homegenie/generic/switch", 1, 1);

var portname = "/dev/ttyUSB0";
SerialPort
  .WithName( portname )
  .Connect( 38400 );   
    When.WebServiceCallReceived("HomeGenie.RFX", ( args ) =>
    {
        string[] reqs = ((string)args).Split('/');
        var res = "{ 'ResponseValue' : 'ERROR' }";
   
        try
        {
            string command = reqs[2];
            var module = Modules.InDomain("HomeGenie.RFX").WithAddress("1").Get();
    switch(command)
    {
         
         
              case "Control.On":
              byte[] message = { 0x0A, 0x14, 0x00, 0x02, 0xF4, 0x5F, 0x59, 0x01, 0x01, 0x00, 0x00 };
                SerialPort.SendMessage(message);
               Program.RaiseEvent(module, "Status.Level", "1", "RFX");
                res = "{ 'ResponseValue' : 'OK' }";
                break;
                           
              case "Control.Off":
              byte[] message2 = { 0x0A, 0x14, 0x00, 0x02, 0xF4, 0x5F, 0x59, 0x00, 0x01, 0x00, 0x00 };
                 SerialPort.SendMessage(message2);
                Program.RaiseEvent(module, "Status.Level", "0", "RFX");
                res = "{ 'ResponseValue' : 'OK' }";
                break;
         
      }
}
catch (Exception ex)
{
    res = ex.Message + " " + ex.StackTrace;
}
// unable to process request
return res;
});
//
Program.GoBackground();

Hi baptist,

when you click on the ON/OFF button the widget will be calling this url:

http://192.168.0.2/api/Components.RFX/1/Control.On/

so

Code: [Select]

When.WebServiceCallReceived("HomeGenie.RFX", ( args ) =>

must be changed in order to handle api calls starting with "Components.RFX" rather than "HomeGenie.RFX"

Code: [Select]

When.WebServiceCallReceived("Components.RFX", ( args ) =>

to see if your program is responding to commands try opening the api url in your browser. It should respond with "{ResponseValue: OK}".

Cheers,
g.

[baptist]

Many Thanks Gene..
That worked.. 

Also the Widget turns the light on / off however the animation of the switch doesn't.. ?

For anyone else who hac RFXCOM 433 + LightwaveRF Switches

Code: [Select]

Program.AddVirtualModules("Components.RFX", "Switch", "homegenie/generic/switch", 1, 1);

var portname = "/dev/ttyUSB0";
SerialPort
  .WithName( portname )
  .Connect( 38400 );   
    When.WebServiceCallReceived("Components.RFX", ( args ) =>
    {
        string[] reqs = ((string)args).Split('/');
        var res = "{ 'ResponseValue' : 'ERROR' }";
   
        try
        {
            string command = reqs[2];
            var module = Modules.InDomain("HomeGenie.RFX").WithAddress("1").Get();
    switch(command)
    {
         
         
              case "Control.On":
              byte[] message = { 0x0A, 0x14, 0x00, 0x02, 0xF4, 0x5F, 0x59, 0x01, 0x01, 0x00, 0x00 };
                SerialPort.SendMessage(message);
               Program.RaiseEvent(module, "Status.Level", "1", "RFX");
                res = "{ 'ResponseValue' : 'OK' }";
                break;
                           
              case "Control.Off":
              byte[] message2 = { 0x0A, 0x14, 0x00, 0x02, 0xF4, 0x5F, 0x59, 0x01, 0x00, 0x00, 0x00 };
                 SerialPort.SendMessage(message2);
                Program.RaiseEvent(module, "Status.Level", "0", "RFX");
                res = "{ 'ResponseValue' : 'OK' }";
                break;
         
      }
}
catch (Exception ex)
{
    res = ex.Message + " " + ex.StackTrace;
}
// unable to process request
return res;
});
//
Program.GoBackground();

Hi baptist... this was a very interactive session =)
Also the module domain specified in your code is wrong. Should be **"Components.RFX"** as well.

Code: [Select]

var module = Modules.InDomain("Components.RFX").WithAddress("1").Get();

so how are you using this piece of code?

Cheers,
g.

[baptist]

Thanks Again Gene, that fixed the animation on the Widget
Brilliant !

I used the RFXmngr software which I downloaded from http://www.rfxcom.com/downloads.htm
to work out the correct byte's to transmit

I also had to upgrade the firmware on the RFXtrx to v77 to get it work correctly with LightwaveRF.

I,ve just got work out have to add multiple switches..

[baptist]

Thanks for the fantastic support, however I'm afraid my lack of knowledge of C# is letting me down.
I managed to get a single switch to work fine, in fact the code below allows one switch to work correctly, also using the api I can get all 3 to operate but no matter how I try I can't get more than one to  oporate from the GUI.. Can anyone advise, much appreciated.

Code: [Select]

Program.AddVirtualModules("Components.RFX433A", "Switch", "homegenie/generic/switch", 1, 3);

Hi baptist,

have a look at the source code of Philips hue. I think it will help.

Hi
Would it be possible to make a homebrew 433MHz RF Transceiver work with RFX433 software? Or do we need to purchase the usb dongle?
