* Drop support for EOL python 3.6
* Add support for setting smart mode thanks to barlock

* Improve startup time when initially connecting to device.

* Fix error caused by adding timeout in v0.5.3.

* Added timeout in listener task to better detect when fans are offline.

* Fix partial status message from device causing listener task to exit from an unhandled exception. Once this happened the device would be deaf to status updates.

* This version should not be used. It has a serious regression that is fixed in v0.5.2.
* Determine a callback type (coroutine or function) only when adding the callback. The reduces overhead in callbacks.
* Callbacks are stopped when the device is waiting for the first update and can only occur when a parameter has changed. Callback frequency has been significantly reduced.
* Thanks go to [bdraco](https://github.com/bdraco) for help in making these changes.
