I have 2 of the second gen nests. There is a plate that installs on the wall(with screws and attaches to the wire), then it kind of snaps into place on the mount. It feels pretty substantial, and I don&#x27;t worry that it will pop off inadvertently. So while the nest itself is nicely built, I feel like the wall plate is kind of chintzy and doesn&#x27;t really look &quot;professional&quot;.
