The Level 1 lock supports Wi-Fi along with NFC. But you can disable the Wi-Fi if you want. But it is a software disable so you have to still trust the software. At least on a Yale lock, the Wi-Fi module is optional and removable. But having it in enables most of the nice features (otherwise it’s just a lock with a passcode you type in).

For me, I feel like I’m gaining more security than I’m losing, so it’s still worth it.
