Hardware
| Install | Retrofit over an existing single deadbolt. Adhesive or screws. Jimmy-proof and mortise locks need an adapter. |
|---|---|
| Size | 122 × 62.6 × 66.8 mm, 367 g with batteries |
| Radio | Bluetooth, per the datasheet (BLE, app and keypad range after the door is closed cited around 20 m) |
| Power | Three 18350 cells, 4200 mAh, plus a CR123A backup. SwitchBot’s pages disagree between about 9 and 12 months at 10 cycles a day. |
| Noise | 50–55 dB at 50 cm, one cycle, per SwitchBot |
Software
| Without a hub | Bluetooth unlock and local control. SwitchBot says a hub is not required for that. |
|---|---|
| With a hub | Remote app control, status, Alexa, Google Assistant, Siri, Matter, and IFTTT require a SwitchBot hub. The product page says Apple Home via Matter goes through the Matter hub. |
| Unlock methods | Fingerprint and keypad show up on some bundles and not others. Confirm whether the keypad is in the box. |
What you buy with it
| What else you buy | A SwitchBot Matter hub if you want Apple Home, voice assistants, or remote unlock. The lock alone is a Bluetooth retrofit. |
|---|---|
| Door | Your original cylinder stays, which is why renters look at this. The interior module is visible. |
| Editorial | Device Radar’s hands-on review discusses Matter over Thread in daily use. The spec row follows the current manufacturer page: budget for the hub. |
Pros and cons
Drawn from the published specifications and what else you have to buy. Not a lab score.
Pros
- • Leaves the existing deadbolt in place.
- • Rechargeable pack plus a backup cell, so a dead main pack is not an instant lockout.
- • Matter and voice are available if you add the hub SwitchBot names.
Cons
- • The manufacturer page does not treat Matter as built into the lock. The hub is a separate line item.
- • Battery-life claims differ across SwitchBot’s own pages.
- • The indoor module is part of the look of the door.
Compare inside Locks
A router can be compared with another router. It cannot be compared with a lock, a bulb, or a speaker.
