The Nest Hello gets big points for including a snapshot from the camera with each notification, so you can get a glimpse of what's happening without having to open the app. The snapshots are extra handy when facial recognition is wrong — which didn't happen often, to be fair. First, the app asked me to identify my family and close friends multiple times from photos the Hello took. You can do this for anyone who comes to your door. I tagged my husband four times, for example, and my son six times. In the Nest app's Familiar Faces gallery, you can tap Select, choose all the instances of the same person, and tap Merge to combine them.
