Transitions
***********

All commands changing the bulb state can be accompanied with a transition, e.g., to slowly fade the light off.
The transition time is in milliseconds, 0 means immediate change.
If no transition value is given, the default setting as configured for the bulb will be used.

.. note::

    Accepted values are command (and potentially bulb) specific, feel free to improve the documentation on accepted values.

    **Example:** While KL130 allows at least up to 15 second transitions for smooth turning off transitions, turning it on will not be so smooth.

Command-line usage
******************

All command-line commands can be used with transition period for smooth changes.


**Example:** Turn the bulb off over a 15 second time period.

.. code::

    $ kasa --type bulb --host <host> off --transition 15000

**Example:** Change the bulb to red with 20% brightness over 15 seconds:

.. code::

    $ kasa --type bulb --host <host> hsv 0 100 20 --transition 15000
