SwitchBot Lock Ultra smart lock

Quick verdict

SwitchBot's flagship retrofit lock connects via Bluetooth locally, which is great for Home Assistant, but you will want a Hub 2 or 3 for Matter and remote access. Fingerprint, NFC, and keypad entry come from the separate Keypad Vision accessory rather than the lock body. Initial calibration requires the SwitchBot app, but after that it integrates well. A solid choice if you are already in the SwitchBot ecosystem.

Standout: Retrofit smart lock with local Bluetooth control plus Matter via Hub; fingerprint, NFC and keypad add on via the separate Keypad Vision.

Avoid if

  • you want a fully cloud-free lock out of the box, since the hub adds WiFi dependency
  • you prefer Z-Wave or Zigbee for whole-home mesh reliability

Privacy and local-control notes

Bluetooth communication is local. Cloud features require a SwitchBot account. Hub 2/3 bridges to WiFi for Matter and remote access.

Home Assistant support: supported · integration path: SwitchBot Matter (via SwitchBot Hub 2/3) plus SwitchBot Bluetooth (local).

Buying reality check

Price notes: Premium pricing, and fingerprint or keypad entry means buying the separate SwitchBot Keypad Vision on top of the lock.
