On the one hand, expecting your remote-controlled lock to work <i>all</i> the time (as in 100% uptime) is unfeasible, since it is impossible to achieve 100% uptime. Almost everyone buying a smart lock probably expected it to have 100% uptime though, and I'm sure they didn't read the small print w.r.t. uptime SLAs.<p>On the other hand, it's probably no more inconvenient than locking yourself out, something that happens every now and again for anyone. Except you don't have yourself to blame, but Nest.
