### Tests

extremely good reason:

### Commits

- [x] My commits all reference Jira issues in their subject lines, and I have 
squashed multiple commits if they address the same issue. In addition, my 
commits follow the guidelines from "[How to write a good git commit 
message](http://chris.beams.io/posts/git-commit/)":
  1. Subject is separated from body by a blank line
  1. Subject is limited to 50 characters (not including Jira issue reference)
  1. Subject does not end with a period
  1. Subject uses the imperative mood ("add", not "adding")
  1. Body wraps at 72 characters
  1. Body explains "what" and "why", not "how"

### Documentation

- [x] In case of new functionality, my PR adds documentation that describes how 
to use it.
  - When adding new operators/hooks/sensors, the autoclass documentation 
generation needs to be added.

### Code Quality

- [x] Passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
