I don’t think this is particularly creative, but it’s very practical… I have an IBeacon receiving station app, Beecon +, that can do webhooks.
So I use the IFTTT webhooks Service/channel to get integration with smartthings that way, including turning on a virtual presence sensor. Fast and easy and no real programming required. 
You should also ask your question in the webcore forum, there’s some interesting stuff being done over there.
