Your problem description is kind of cryptic and I think you meant to post this in the [RELEASE] H801 & Other ESP8266 Based RGBW Controllers (SmartLife) thread to get support from the developer.
Can't determine if Alexa or Google even see the devices based on your description.
Did you check your Alexa or Google Home app to see if the devices are present? You should start there to see where the issue is. For me in Alexa, the steps are from the main Hubitat home screen, click Apps, click Amazon Echo Skill, then select the new devices that the driver builds for you IF you manually created them using the enable. The new driver is creating a virtual switches and you are saying the physical parent device shows up in Alexa and Google Home and is controllable but not the child devices?
I just tested mine and the parent and my child devices are controlling fine by Amazon Echo.
