Kepler

When running a sensor workflow (importing the localhost sensor simulator site), I will intermittently encounter one of three exceptions. I haven't checked, but I suspect that any sensor names given are not consistent between instances of an exception. Kepler will intercept the exception properly, and display an error message, stopping the workflow.

The exceptions are attached below:
