Changes made from HomeKit/Homebridge are sent to AWS but nothing actually happens on the device
### What issue do you have? Please be as thorough and explicit as possible.

I've set up my light strip (H6159) successfully, and it works fine directly from the Govee app. I've installed `homebridge-govee` and provided credentials. It shows my device and I can see it in Homekit. 

When I make a change in Homebridge or Homekit the light doesn't change. The log shows that the command is being sent though. If I change the light using the Govee app the log in homebridge shows it receiving the state change. 


### Details of your setup.
* Do you use (1) Homebridge UI-X (2) Homebridge CLI or (3) HOOBS? 

Homebridge UI-X


* Which version of Homebridge/HOOBS do you have?

1.4.0



* 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.

Docker (`oznu/homebridge:latest`)

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

`homebridge-govee v4.28.0`

First time I've used it.

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