my_device = GoveeDevice('D4:AD:FC:33:0A:D9')
my_device.setPower(False)

Device is H619A RGBIC

From what I've researched, it appears that H619A's packets differ from H6127, the device this API was mainly made for. I'm doing some research as to what the packets are for your device.

I've found https://github.com/bwp91/homebridge-govee which has an API for the H619A, but the program is only for HomeBridge with integrates HomeKit devices.

I'm going to keep searching through their source code and try to get in contact with the developer to see if I can get the packet codes, but at the moment it appears the H619A won't work with this. I'll keep you updated and let you know if I find anything! :-)

Also, the H619A has support for Alexa and Google Home according to Amazon, so implementing something there (for example with https://github.com/greghesp/assistant-relay) or with Govee's API (like with https://github.com/LaggAt/python-govee-api, which I believe would work since the lights can be controlled through WiFi).

Just a thought, I'll continue working on this though to try and support more devices :-)

Thanks for continuing to look into this, the Govee WiFi API is extremely limited, and very slow, so I was hoping this library would work :)

If there is any debugging information you would like, please let me know.
