Honestly? Not much, really. As long as there's a backup in case you lose your phone (some have a regular key lock, some require a passcode) then you'll be fine. Thieves aren't going to hack your smart lock, they'll just crowbar the door or throw a brick through a window.

Critical infrastructure aside, hooking up every day objects like scales and other appliances (I'm looking forward to notifications such as "Your washing is ready" or "Your pizza might be burning") is potentially really useful. There'll be rough spots at first - configuring these devices right now isn't great - but hopefully systems like Homekit are going to help with the setup and administration of these devices.
