And before I forget...
Can I send a UDP (user datagram protocol) packet out on the network? I like to use UDP to tell other servers status updates. I have LCD's in my house that display status, and they listen for UDP packets.
So far, the best I have been able to do is use a macro to call a VB program which creates a socket then sends the packet and exits. Not very efficient.
While we are on the topic, is there a way to listen on a port for a packet to arrive. I am aware of the socket server, but that is TCP and is heavyweight. I'm looking for a lightweight UDP socket to respond to packets.

Not sure if this is TCP or UDP, but...
What about the ph_sendsocketdata formula?
ph_sendsocketdata ( url, port, data )
For receiving packets, I believe that you need to set up a trigger of type Socket.

I just tested ph_sendsocketdata("192.168.0.2",9000,"test") and it connects using TCP. It works, but I would love to have UDP for broadcast. With UDP you can set the destination address to "255.255.255.255" and all of your listening servers will get the info at about the same time. It is an excellent way to cut down network traffic.

Ok, the socket triggers are tough :)
Here is what I have done. I encoded jason:none into base64. I can connect to the PH socket server and send it text. I'm sure that I am connecting. Here is the text that I send it:
FORMULA\nAuthorization: Basic amFzb246bm9uZQ==\nContent-Length: 15\n\nph_tts("Hello")
I have a socket trigger setup to call a macro called TEST. I know that ph_tts works because I have called it from other macros. I neither hear text nor have macro TEST run. I am guessing that the socket server does not like my data.

Jason,
PowerHome currently only has the Socket formulas. No support for UDP at the moment (I'll have to do some reading and educate myself  ). If you've got some simple VB type code or similar that illustrates the functionality, I'll be happy to add support.
Yep, ph_sendsocketdata is TCP. You may also want to check out the ph_ping function for Ping capabilities.
Currently, the only way to listen on a port is with the Socket Server or the Web Server. With the next beta though, you'll be able to code up a simple ActiveX control in VB that can listen on any port for any type of traffic that you're interested in and respond to triggers or whatever.
The Socket Triggers work with the Socket Server. It's just a way to fire a trigger based upon an incoming Socket Server command. The Socket triggers do not work independently. You could get away without even having a Socket Trigger if you use a Socket Server command type of FORMULA and just pass the actual formula that you want to have evaluated. You can use the ph_ssrequest function in another instance of PowerHome or the DCC to create properly formatted Socket Server requests. Also, on the download page, check out the VB source code for PHSSCMD.EXE to see just how to put together a Socket Server command request.
Concerning your SS request string...it looks ok from this end. It should do the TTS just fine as long as the authorization matches your SS and of course the port and SS is setup and enabled. However, FORMULA will not fire a trigger and would require you to use FORMULATRIGGER to run a formula AND fire a trigger. You could also use TRIGGER1 thru TRIGGER5 to just fire the appropriate trigger without evaluating the formula.
Let me know if this helps,
Dave.

UDP is insanely easy. To do a UDP send in Visual Basic, you add a Winsock control. The following code will broadcast a packet:
winsockout.Protocol = sckUDPProtocol
winsockout.RemoteHost = "255.255.255.255"
winsockout.RemotePort = 1000
winsockout.SendData = "hello"
It is a connectionless protocol, so there is no connect or close.
On the other end, to set up a listener, you do the following:
winsockin.bind 1000
When a packet arrives, it will show up in the winsockin_DataArrival function. You get the data with
winsockin.GetData strData
That's it. I would like to be able to bind to a port, and when data arrives on that port, fire off a triggered event.
I would also like to be able to call a function like this:
ph_sendudp("255.255.255.255", 1000, "hello")
and that would send a UDP packet out to the broadcast address. My entire HA is done with UDP so I can share more if you like.

Looks pretty easy. I'll code it up so it'll be in the next beta.

Thanks! Between UDP, more than 5 com handles and a plug in archtitechture, I think I'll be really happy.
Thanks for all the hard work.

Already coded it up. There is a new ph_sendudp function built-in to PowerHome and Ive gone ahead and created a UDP Listener Plugin that utilizes the new PowerHome plugin architecture.

Sweet! That was fast. So when will the beta be available?

Jason,
Heh, hopefully very soon. Im right in the middle of recoding the Insteon to handle the new Status and level methodology. There are over a 1000 lines of code that has to change just for this 1 modification (I got a little over 300 done last night).
Anyways, there are a few more tweaks that I need to get in and then I've got to code up the Database Upgrade Utility. If I had to put a time on it (people that have been around here awhile know how much I hate to do that  ), I would probably say Im looking at a little less than 2 weeks.
Dave.

(warning: hot stick poking to follow)
So I waited the required 2 weeks before bugging you again.
Any idea when the new beta will be out? I'm very excited about the controller arch changes and the UDP stuff.
