Help For Beginner


(Jack Butch Griffin) #1

I am trying to learn to write a simple app. I want to monitor a switch for a given light and turn on another light based on the original switch. The code is shown below. For a while I got nothing to happen at all. Now, I can save my code and publish “For Me”. The app shows up on my iPhone and I can try to install it. After setting “theInputSwitch”, “theOutputSwitch”, and the name of the app, I hit done and get …

org.springframework.security.access.AccessDeniedException: Access is denied

Any clues? This is frustrating for a beginner. Note, I know this is like the app “BigSwitch”. I was just using it as an example to begin to understand the development process and what is possible.

Thanks

The problem is in

subscribe("theInputSwitch", "switch.on", switchOnHandler)

It should be this instead

subscribe(theInputSwitch, "switch.on", switchOnHandler)
