You now have another (and potentially better) option if you want a Schlage lock that can let Amazon couriers into your home. The company has unveiled the Encode, the first WiFi-equipped deadbolt that supports Key by Amazon. Unlike the Connect, you don't need a hub -- you just install the lock and fire up the app. It unsurprisingly plays well with Ring's devices, too. You now have the option to let people in when watching live video from a Ring doorbell or camera.
