That is were switching from the Govee Cloud to using the Lan API comes in.
The rate limit for Govee cloud is 10 changes in a min. And some commands in Hubitat can quickly churn through multiple cloud calls and that 10. Calls. So now that you have this working. Leave it alone and lets get the LAN API enabled for the device.
Start by opening the Govee home app and going to the device. Open the device settings and wait about 10- 15 seconds and you should see a option for lan control. Turn it on and leave the setting page. Get the ip of the devices and provide it a DHCP reservation on your router so it doesn't change. Then on the device page in Hubitat change the switch to enable the Local Lan control and click Save. Once that is done the driver switches to Lan commands. Now enter the ip address for the device in the IP address box that appears and click save again.
Now test if control is still avaliable. If it is Lan control has been properly setup. If it doesn't work make sure the ip is right and Lan control is enabled for the device settings in the Gove Home App.
Once this is done you know longer have any rate limits.
