This awesome little device, called Sesame by Candy House, is being sold as another smart door lock with bluetooth, mobile app, blah blah – who cares?! This thing can recognize a secret lock and open the door just for you!! If you want a regular old smart lock, there are dozens available. They don’t excite me just make me concerned someone is going to hack it and break in. I’d prefer to turn that feature off of this little killer and only use the secret knock. Did you hear me? SECRET. KNOCK. Most smart locks are at least $150 and go quickly up above $200. Sesame is pre-selling for $99. I think I’m going to get one.
