### What issue do you have? Please be as thorough and explicit as possible.

The brightness adjust slider for H6054 appears to be inaccurate- the slider doesn’t seem to go above the 40% mark, but that is actually 100% on the actual light. In other words I can control 100% of the light but only using the bottom 40% of the brightness slider in HomeKit. I have another light, a different model, and the slider works fine.


### Details of your setup.
* Do you use (1) Homebridge (+ config-ui), (2) Homebridge (CLI) or (3) HOOBS? 

(1) Homebridge (+ config-ui)

* Which version of Homebridge/HOOBS do you have?

* Which platform do you run Homebridge/HOOBS on (e.g. Raspberry Pi/Windows/HOOBS Box)? Please also mention your version of Node.js/NPM if known.

Raspberry Pi 3B+

* Which version of this plugin (homebridge-govee) do you have? Has the issue started since upgrading from a previous version?

Latest 3.3.0 but it was also present in the previous version (I started using this on the version prior to 3.3.0 - big thanks, it’s a fantastic plug-in and works really well even despite this minor UI issue on this particular model - thank you!!)

* Which Govee devices do you have that are causing issues? Please include product models if applicable.

H6054
