 bri | 0 to 255 | Brightness of the light. If _on_ is `false`, contains last brightness when light was on (aka brightness when _on_ is set to true). Setting _bri_ to 0 is supported but it is recommended to use the range 1-255 and use `on: false` to turn off. The state response will never have the value `0` for _bri_.
 transition | 0 to 65535 | Duration of the crossfade between different colors/brightness levels. One unit is 100ms, so a value of `4` results in atransition of 400ms.
