A:Answer What do you want it to do with your Nest system and which device do you mean (camera, thermostat, etc)? I don't think Nest has any direct compatibility with this at all. It does however talk to Apple HomeKit (using Apple TV as the hub), which also talks to Nest devices. I have mine set up to let me unlock/lock from my phone, and even automatically unlock when I get home after sundown.
