&gt; Mmmh, what could possibly go wrong with that?<p>Honestly? Not much, really. As long as there&#x27;s a backup in case you lose your phone (some have a regular key lock, some require a passcode) then you&#x27;ll be fine. Thieves aren&#x27;t going to hack your smart lock, they&#x27;ll just crowbar the door or throw a brick through a window.<p>Critical infrastructure aside, hooking up every day objects like scales and other appliances (I&#x27;m looking forward to notifications such as &quot;Your washing is ready&quot; or &quot;Your pizza might be burning&quot;) is potentially really useful. There&#x27;ll be rough spots at first - configuring these devices right now isn&#x27;t great - but hopefully systems like Homekit are going to help with the setup and administration of these devices.
