your path in your hubaction isn’t defined, its just sending “GET path HTTP/1.1”

Updated:
def headers = [:]
headers.put("HOST", "$ip:$port")
log.debug "The Header is $headers"
def method = "GET"
try {
def hubAction = new physicalgraph.device.HubAction(
method: method,
path: "/",
headers: headers,
device.deviceNetworkId
)
log.debug hubAction
hubAction
}
catch(Exception ex) {
log.debug "Hit Exception $e on $hubAction"
}
I also tried replacing hubAction at the end of the try block with sendHubCommand(hubAction) but it made no difference. Would the issue have anything to do with UPNP?
UPNP is something completely different. What are you trying to do?
Just get the body of the html and parse through it. I have read the method used depends on if you are building a device handler or a smartapp. In my case I am trying to build a device handler, I also read that in some case you use mac address and some ip and in some ip:port in hex. I have been playing with all of these but with no luck so I was looking at UPNP but this was just me grasping at straws to figure out why the parse function never fires.
def parse(String description) {
log.debug "Parsing '${description}'"
def msg = parseLanMessage(description)
log.debug msg
}Also not sure if it matters but I have only tried this in the simulator.
Thanks
I tried running the hub action which was printed out in the logs in putty
so I ran
"GET / HTTP/1.1
Accept: /
User-Agent: Linux UPnP/1.0 SmartThings
HOST: 192.168.1.7:80"
and got the following so I know the GET is working. Pasting html in here doesn’t work so just pasting the non html
HTTP/1.1 200 OK
Content-Type: text/html
ESP8266 Temperature Sensor
Temp F: 80.82
Temp C: 27.12
any other ideas?
so you are getting a response? What’s the issue?
No response the parse function is never triggered. I am only getting the response in putty or the browser.
I just cane across this so I will try it and see what happens.
Just an update to let you know I got it to work with the fork of the SmartThing library I linked above
Hi can you share the code, and how you got it to work ? please
Hi sorry my code isn’t very clean but hear it is. I must say I ended up scrapping the project and haven’t had time to go back to it due to the fact that it was draining an entire 9v battery overnight.

Hopefully this helps. For the ESP8266 be sure to include the right libraries found here https://github.com/DanielOgorchock/ST_Anything/tree/master/Arduino/libraries/SmartThings
