Hey,
you can turn the device “on” and “off” with your Homey an set a static color. i think, a developer can build a goodone app… but i dont be a dev 
First, you must get a API Key from Govee. You can get it in the govee APP under your Profile ->About us -> Get API Key. You will receive a key instandly to your Emailadress with the actually API reference.
After that you must become out which device ID your device has. I have use the Chrome extention “Advanced REST client”.
You create a new “GET” request - in the header you must add your “govee-api-key” (the key which you become per email). After you send the call you will recive a list of your devices. here can you see the answer.
You need the DeviceID for the next step.
Back to homey you need to create a new flow:
(for the break in the header section you can use Shift+Enter in the Browaserapp https://flow.homey.app/)
thats all. You can copy that flow an edit “off” in the Body to “on”.
If you has more ideas, tell me plase
Good luck
