Does anyone have motion detection working with the new Nest Cam functionality?
Currently the answer seems to be “No” insofar as the Nest camera sensors are not properly polled. (They are polled once at startup, and then, as far as I can tell, not refreshed.) In diagnosing the problem, one can dig into the code and find the illuminating comment “This doesn’t seem to be getting called regularly, for some reason.”
As I just started using Home Assistant a couple hours ago, I don’t know if I have it in me to figure it out tonight, but hopefully soon.
Is this still the case? I just added my Nest Cam and would like to set up some automation based on motion/sound detected by the camera.
Any news on this topic? 
I have a Nest Cam and I get motion detection events from the HA integration.
Is it the outdoor cam? I am wondering if I need a subscription to the nest service in order for the sensors to work?
No it’s the original indoor one. I do have a subscription to Nest Aware but I don’t think that’s necessary for basic motion alerts, but I could be wrong.
