I’ve been trying to create an Arduino device type that will place the hub into a listen mode for arduino commands. I have several very inexpensive 433 Mhz motion sensors and contact sensors that interface to an arduino. Then the Arduino is sending a command to a Maker channel on IFTTT, and the recipe turns on a simulated light on smartthings. Then I have a smartapp in smartthings that polls the arduino via the ethernet shield when that simulated light is turned on.
Obviously this method is heavily dependent on multiple services functioning as intended and will have issues. The round trip time is actually less than 5 seconds normally. However, it would be MUCH easier if I could figure out how to have the arduino simply send the hub commands locally.
Can anyone help me get started on the local network access from my arduino to the hub?
