I return JSON from my web api. However, I have managed to get it working! Turns out I did not assign my device to a hub, so the local commands were not being sent anywhere. There was no debug info in the log output… and no mention of it in the api docs. But oh well, I managed to get local HTTP GET / POST commands working 
Took all day, but its done…
I do have a question though, it appears that whenever you call hubAction, the response always goes to def parse { }… However, is there anyway to get it to goto a different method? I may need to treat the data differently based on what comes back :S
Thanks for the reply
