* First round of not using values directly * Round two * lint * Round four * Conflict * Round five * Update zwave.py * round six * Docstring * flakywakie * Fetch values in constructor * Blank line removal * Set attributes in callback * Docstring * Round seven * Ughgit add homeassistant/components/lock/zwave.py! * Sloppy code
