ZHA - Philips Hue Dimmer Switch - V2

hue_dimmer_switchV2.yaml

blueprint:
  name: ZHA - Philips Hue Dimmer Switch - V2
  description: |
    Control lights with a Philips Hue Dimmer Switch.

    The top "on" button behaviour is adjustable. By default it behaves like this:
      - Press it while the light is off, and the light will turn on to the last set brightness.
      - Press it again while the light is on, the light will turn to the fixed brightness setting.
    
    Dim up/down buttons will change the brightness smoothly and can be pressed
    and hold until the brightness is satisfactory.

    The bottom "off" button will turn the light off.
    
    The "on" and "off" buttons can be assigned to an action when double
    or triple pressed. This allows you to assign e.g. a scene or something else.

    The minimum brightness setting will limit how low you can set the brightness. This will 
    prevent dimming down until the light turns off. Set this to zero to disable this feature.

    Does this blueprint not work for you? Did you add your Hue dimmer to ZHA before July 2020?
    It might help to press the 'Reconfigure device' button on the ZHA Device info page.
    The naming of the command attribute in the zha_event was changed back then.

It seems that PR home-assistant/core#71687 will be breaking for this Blueprint. I fixed it in this version: https://gist.github.com/agners/6871de29e68b00aa2eed2c503196ac16

@agners Thanks for this! Worked great for me.
