WLED/Google Assistant

I used the joyfulhouse driver to connect my WLED device (ESP8266) into HE and I'm trying to give my kids the ability to control the color through Google Assistant (too young for phones) but google only sees it as an on/off device. Did I misconfigure something or is this a limitation? Suggestions for a workaround?

From other posts I am gathering that the google integration is looking for current states that this driver may not have?

Also, less importantly, the states arent updating when it changes outside of HE. I do have it connected to HA (run both in parallel for different things) and it gets states fine on HA so I know the APIs and device are functioning. Again, did I do something wrong?

Thanks in advance for the help!
