SwitchBot Presence Sensor

Compiled by SmartHomeWorkflow Research · SwitchBot · Sensors & Detectors · ~$29.99 (SwitchBot's own US store price for the sensor on its own, checked again on 2026-09-17 and unchanged from what we recorded on 2026-07-19 — a price at the time of research, never a live price. The bundle figures that follow are from the earlier 2026-07-19 check and were not looked at again: the other 'Presence Sensor' listings are bundles of the same unit (Hub Mini Matter combo $59.99, Bot 2-in-1 $52.99, 2-pack $54.99).)

“Not established” means we have not sourced that detail yet — not that the product has no model number, generation or regional variant. We publish the gap rather than filling it.

Compatibility

EcosystemSupportThe catch
Amazon AlexaWorksWorks with this ecosystem[6]Requires a SwitchBot hub (Hub Mini, Hub 2, Hub Mini Matter Enabled or Hub 3); SwitchBot publishes a dedicated setup guide.
Google HomePartialPartial support — see the catch[6]Requires a hub, and SwitchBot documents a hard platform limit: Google Home does not allow the sensor to be used as an automation CONDITION at all. It reports state and nothing more — which for a presence sensor removes most of the reason to buy one.
Apple HomePartialPartial support — see the catch[6][12]Requires both a SwitchBot hub and an Apple Matter controller (HomePod or Apple TV). It arrives bridged rather than native, and bridged SwitchBot devices can surface under Matter Setup > Secondary Devices > Lab Feature (Beta) rather than as an ordinary accessory.
SmartThingsPartialPartial support — see the catch[6]Requires a hub. SmartThings appears in SwitchBot's platform enumeration, but no dedicated setup guide or capability detail was found, so which entities and attributes actually surface is unconfirmed.
Home AssistantWorksWorks with this ecosystem[6][21]The one ecosystem that does NOT need a hub — Home Assistant's Bluetooth integration talks to the sensor directly. A cloud integration also exists and that path does require a hub.

Protocols: BLUETOOTH[1][5][15][19]

What it can do[14][21]

You can tell it to

None documented by the vendor

It reports

  • Presence detected
  • Illuminance reading

Whether each platform's automations and routines can use it — not just whether its app shows it.

Platform documentation: Amazon Alexa — automation engine ceiling (eight terms observed; residue inconclusive by refusal) (2026-09-01), Apple Home — automation engine ceiling (2026-09-01), Google Home — automation engine ceiling (2026-09-01), Home Assistant — automation engine ceiling (2026-08-29), SmartThings — automation engine ceiling (2026-09-01)

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality[11][19]

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

No subscription found and no vendor statement of one. Re-checked at the vendor's own structured product route on 2026-09-17: the listing sells the sensor once at $29.99 and names no plan, tier or paid service.

Maintenance reality[3]

The catch

The hub economics matter more than the $29.99 price. Without a SwitchBot hub you get app viewing plus 'Local Linkage', which is capped at two linkages driving one device each, both within Bluetooth range — everything else, including all voice assistants and Matter, needs a hub you buy separately. The exception runs opposite to expectation: Home Assistant reaches it over Bluetooth with no hub at all. And in Google Home the sensor cannot be used as an automation condition, which is most of what a presence sensor is for.

Who it's for

Home Assistant households wanting cheap mmWave presence with no hub purchase, or SwitchBot owners who already run a hub. A Google Home household should read the automation-condition limit before buying.

21 numbered sources· read them in the source's own words
  1. [1] Home Assistant's SwitchBot integration is a BLUETOOTH integration — it states in its own words that "A SwitchBot Hub is not required for this integration" — and it names this device with control features, which is a usable control path under the ruled definition. Presence Sensor features: get light level, get battery, get occupancy state — with the documented caveat that "Device battery data is stored in service data, not broadcast. This data can only be retrieved when Bluetooth is in active mode." ⚠ SwitchBot's own product description (read 2026-08-09 from the store's structured product data) contains ZERO occurrences of "Bluetooth"; the 19 occurrences on the rendered page belong to other products' embedded copy., verified 2026-08-09

No 'Motion Sensor 3' and no separate 'Human Presence Sensor' exist in the US catalog. Naming is inconsistent across SwitchBot's own properties — the US store says 'mmWave Presence Sensor' while the EU store, press release and every support article say 'Presence Sensor'; the short name is recorded with the long one as an alias. — Read on the maker's own site, verified 2026-07-19

Product page gives 8m moving / 5m stationary detection at 120 degrees.

  4. [4] SwitchBot support articles 35160600522775 and 35615000659095 — the sensor's own radio is Bluetooth; without a hub it supports app viewing and 'Local Linkage', capped at a maximum of two local linkages driving one device each with both units in Bluetooth range. To trigger other devices via SwitchBot automation 'you will need to purchase one of hub products'. Remote access, cloud automation, all voice assistants and all Matter exposure require a hub. — Read on the maker's own site, verified 2026-07-19
    Backs: Required hub or bridge
  5. [5] SwitchBot support articles 38979658026519 and 35927178604311 — the hub acts as a 'protocol translator' converting Bluetooth to Matter; the sensor is not itself a Matter device. Matter does define an Occupancy Sensor device type, so a suitable target exists, but SwitchBot never states which Matter device type or cluster it maps to. — Read on the maker's own site, verified 2026-07-19

  7. [7] support.switch-bot.com sits behind a Cloudflare bot challenge, which was not bypassed.

Flagged rather than presented as full-text verification., verified 2026-07-19
  8. [8] An Amazon listing title claims 'Zone Positioning' but no primary SwitchBot source corroborates distance or multi-zone reporting; SwitchBot's own 'zone' language refers only to physically aiming the magnetic base. The sensor reports a binary Space-Occupied / Space-Unoccupied state plus an unoccupied timer. Deliberately excluded rather than carried over from a marketplace listing., verified 2026-07-19

  13. [13] SmartHomeWorkflow capabilities assessment, 2026-08-20. Home Assistant's SwitchBot integration was read in full and enumerates "Motion Sensor (WoPresence)" with motion detection state and battery — but the mmWave Presence Sensor recorded here is a different, newer product and is NOT named anywhere in that device list.
