This device could be perfect... :-)

Right now there is limited Alexa functionality compared to the doorbell camera. All I can do is toggle person detection and turn the camera on/off (I can't confirm that does anything)

From Alexa, I should be able to:
1.  see the live video -- the same as the doorbell camera
2.  Expose the flood lights so I can turn them on and off using Alexa. 

Perhaps the c720 needs to be exposed to Alexa as 2 devices -- a camera and as a light that can be controlled separately
