Rather than continue to hijack Bob's thread, starting a new one here.
The Nest camera 'eco-system' is a perfect example of 'flakey'. I have reinstalled the camera several times. I have even had the camera replaced. I have reinstalled the Nest app on the mobile - also several times. To little avail.
Typical issues are :
Home/Away Assist doesn't. I can be away from home and the Nest app on the phone shows Away and yet the camera has not been switched on.
Huge gaps in the event recorded history. Known events, such as me leaving the house early yesterday morning, fail to appear or be recorded.
Frequently the 'eco-system' will complain that my camera is offline and yet i can quite happily Ping it from my Mac. So it isn't offline.
Lies on their website regarding how Home/Away Assist works. They claim location is based on which mobile mast, wi-fi and GPS. The last two are 100% incorrect and a complete and utter 'con'. They do not know how to use the Fused Location Provider in Android properly.
Recommended ? Nope.
