This post is for @Ben, @tslagle13, @pstuart, @adam, and whomever else can help. I’m trying to create a local LAN device type that is able to send a POST request and receive a response back from it. It took me a while to figure out that my Device Id needed to be my device IP and port encoded as hex and also that the response from the POST method is handled by the parse method.
I’ve created the following code but can’t seem to get it to show up on my LAN device logs. Any help is appreciated.
Method: POST
IP: 192.168.1.150
Port: 8000
Authenticaion: Basic
path: /macros/getCPUTemp
Edit: My ST logs are as follows:
12:03:31 PM:
debug POST /marcos/getCPUTemp HTTP/1.1
Accept: */*
User-Agent: Linux UPnP/1.0 SmartThings
HOST: 192.168.1.150:8000
Authorization: Basic d2ViaW9waTpxXxxxxxxxxX=
