SwitchBot's original, cheapest lock — the entry point below Lock Pro and Lock Ultra. It clips over an existing euro-cylinder thumbturn with adhesive mount and adaptors, no drilling. Bluetooth is the only radio built into the lock itself; a 2023 firmware update (Smart Lock firmware v6.5) added Matter support, but only when bridged through an optional SwitchBot Hub 2 or Hub Mini (Matter-enabled), for Apple Home, Alexa and Google Home. Home Assistant doesn't need any hub, though — the switchbot integration controls it directly over local Bluetooth. Runs on two CR123A batteries, rated ~180 days at ten cycles a day. Auto-lock re-engages on a configurable delay after the door closes. Oddly, Lock Pro sometimes undercuts this on Amazon UK, and Lock Ultra costs more than double via the direct store — buy this one only if you don't need Ultra's half-lock mode.
What can Home Assistant control on the SwitchBot Lock?
| Control | Type | What it does |
|---|---|---|
| Lock | Lock | Primary lock/unlock control via local Bluetooth, no hub required. |
| Door state | Sensor | Open/closed state derived from the lock's internal position sensing, not a separate door contact accessory. |
| Auto-lock paused | Binary sensor | Reflects whether the device's auto-relock timer is currently suspended. |
| Calibration | Sensor | Flags when the clip-on adhesive mount has drifted out of alignment with the thumbturn — the most common failure mode on this model. |
| Battery | Sensor (%) | Battery percentage; reported to read high for extended periods before dropping sharply, so treat as a rough indicator rather than a precise threshold trigger. |
Despite being the older, cheaper hardware, the base Lock exposes the identical HA entity set as Lock Ultra via the same local switchbot integration — lock/unlock, door open/closed state, auto-lock-paused, calibration state, and battery — so buying down from Ultra costs no automation hooks. What it does lack is Ultra's half-lock/nightlatch control. Like Ultra, the lock itself has no built-in Matter radio, but a 2023 firmware update lets it be bridged to Matter through an optional Hub 2 or Hub Mini (Matter-enabled) — so the same dual Bluetooth/Matter entity duplication that can trip up Ultra owners is possible here too if you commission the lock via both a Matter hub and HA's direct Bluetooth switchbot integration at once; stick to one path to avoid two lock entities for the same device. The dominant real-world failure reported by long-time owners isn't an integration bug but the clip-on adhesive mount slipping on the thumbturn over months of use, which surfaces first as calibration state flipping to uncalibrated rather than as a failed unlock call.

Frequently asked questions
- Does the SwitchBot Lock work with Home Assistant locally?
- Yes. The SwitchBot Lock 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 use, and do I need a hub?
- The SwitchBot Lock uses Bluetooth and Matter. To pair it with Home Assistant you need a Bluetooth adapter on your Home Assistant host or an ESPHome Bluetooth proxy; 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 cost in the UK?
- The lowest price we have listed for the SwitchBot Lock is £129.99 at SwitchBot UK store. Prices were last checked in September 2026 and change often, so confirm on the retailer's page before buying.
