I have some IP security cameras that are aggregated/managed by ispy. Ispy has a remote command syntax that allows me to do things like trigger a camera to take a snapshot. I would like to be able to send the HTTP string from the hub to the PC running ispy. I haven’t found documentation on how to send data on the LAN from the hub. Pointers anyone?
Eric
Reason is - By sending across the LAN I wouldn’t have to worry (as much) about authentication.
This feature has just recently been added, and there is no documentation, yet.
You can either take a look at existing device handlers, in order to figure out how it’s done, or wait for the documentation, which we have been promised will come soon.
You could do it with port forwarding but that is opening up a hole that you probably don’t want to open up.
httpGet(url) {
response ->
if (response.status != 200 ) {
log.debug "Webserver failed, status = ${response.status}"
}
}
I’m after the same thing I believe as I want smartthings to send a HTTP command to my server once a change in presence is detected.
I found this: http://build.smartthings.com/forums/topic/smartthings-labs-and-lan-devices/
Maybe it helps you to move a bit further and please update here if it does.
I’m tinkering with my presence stuff in the meantime and see if I get anywhere… 
idefix:
I responded to your other thread. Thank you so much for that tip and link - that got me over the top - I have it working. I posted the code on your other thread. Thanks!!
Eric
This link is no longer leading to its intended page and I was so excited that I might finally get to make my ispy work with presence detectors. Can someone help me with this ? I have tried thousands of permutations of httpget and so far nothing but working push messages with no effect on the ispy server. Pleeeeasse ! 
would you share the code that worked for you with me ?

sendHubCommand(new physicalgraph.device.HubAction("""GET /snapshot?ot=2&oid=$camera1 HTTP/1.1\r\nHOST: $ip\r\n\r\n""", physicalgraph.device.Protocol.LAN, "${deviceNetworkId}"))

I have now transitioned to the new hub and this code (which I believe is entirely cloud-based) is still working.
It does work, indeed ! Thanks a lot!
