The mid-tier step below Lock Ultra: SwitchBot's own listing explicitly confirms it fits European cylinders, British oval cylinders and Swiss round cylinders, with eight cylinder adaptors included in the box — no separate adapter purchase like the cheaper original Lock. The base Bluetooth model needs no hub at all for Home Assistant, since the official switchbot integration talks to it directly over local BLE; only Lock Ultra carries the full Works with Home Assistant badge, Lock Pro uses the same core integration but isn't separately certified. It sits meaningfully above the base Lock and below Ultra on price, and adds SwitchBot's own quieter/faster motor generation plus the persistent-calibration behaviour covered below.
What can Home Assistant control on the SwitchBot Lock Pro?
| Control | Type | What it does |
|---|---|---|
| Lock | Lock | Primary lock/unlock control sent over local Bluetooth; same command surface as the base Lock and Lock Ultra, but only Lock Ultra additionally exposes a half-lock service. |
| Door state | Binary sensor | Reports whether the door itself is open or closed, letting an automation refuse to auto-lock, or fire an unclosed alert, while the door is actually ajar. |
| Calibration | Binary sensor | Reflects whether the lock's mechanical throw is calibrated; on Lock Pro this state survives battery changes, so it stays on through a battery swap instead of dropping to unknown. |
| Auto-lock paused | Binary sensor | Turns on when the device's own auto-lock timer has been paused, useful for alerting when the physical auto-lock silently stops running. |
| Battery | Sensor (%) | Battery level for the lock body itself. |
Lock Pro's calibration state persists across battery removal — unlike the base Lock, which clears it — so a battery swap won't leave Home Assistant's lock entity briefly untrustworthy while it waits for you to recalibrate in the SwitchBot app. SwitchBot's auto-unlock geofencing feature is a phone-side Bluetooth+GPS feature handled entirely inside the SwitchBot app and never surfaces as an entity, attribute, or trigger in the switchbot integration, so it can't be referenced from HA automations at all. Neither the separate built-in Wi-Fi SKU nor this Amazon listing's bundled Hub Mini (Matter Enabled) changes any of this for HA: local control still goes over Bluetooth exactly as with the plain hub-less lock, since the Wi-Fi radio and the bundled hub's Matter bridge only serve SwitchBot's own cloud app and Apple Home/Alexa/Google Home respectively, not the local switchbot integration — there's no Matter or Wi-Fi entity path into Home Assistant for this device.
Specs
| door fit | European cylinders, British oval cylinders, Swiss round cylinders and knob cylinders; 8 cylinder adaptors included |
|---|---|
| wifi variant | A separate built-in Wi-Fi SKU (Lock Pro Wifi) is sold for remote/app access without a SwitchBot Hub |
| amazon bundle note | The linked Amazon UK ASIN (B0CYNVQ19H) is the 'Lock Pro + Hub Mini (Matter Enabled)' bundle, not the plain hub-less lock — the box includes a Matter-capable Hub Mini for Apple Home/Alexa/Google Home, on top of the lock body's own Bluetooth radio |
| hub required for ha | None — official switchbot integration controls it directly over local Bluetooth, regardless of which Lock Pro variant or bundle is purchased |

Frequently asked questions
- Does the SwitchBot Lock Pro work with Home Assistant locally?
- Yes. The SwitchBot Lock Pro is controlled locally in Home Assistant through a built-in Home Assistant core integration (switchbot), so it keeps working if your internet connection or the SwitchBot cloud goes down. Control and state updates stay on your own network.
- Which protocol does the SwitchBot Lock Pro use, and do I need a hub?
- The SwitchBot Lock Pro uses Bluetooth and Wi-Fi and Matter. To pair it with Home Assistant you need a Bluetooth adapter on your Home Assistant host or an ESPHome Bluetooth proxy; or no hub — it joins your Wi-Fi network directly; or a Thread border router if it is Matter-over-Thread, or just your Wi-Fi network if it is Matter-over-Wi-Fi. SwitchBot's own hub is not required when you integrate through a built-in Home Assistant core integration (switchbot).
- How much does the SwitchBot Lock Pro cost in the UK?
- The lowest price we have listed for the SwitchBot Lock Pro is £99.99 at Amazon UK. Prices were last checked in September 2026 and change often, so confirm on the retailer's page before buying.
