## At a glance

- mmWave radar, PIR and a light sensor are described as detecting movement and subtle chest movements while a person is still.
- Basic linkage with SwitchBot devices is claimed to work without a hub, with up to two automations. A hub is needed for more complex scenarios and for stated Matter integrations.
- Magnetic base is described for flat placement, wall mounting and adjusting the detection direction.
- Listing describes a 120° field, with separate ranges for moving and stationary people.

## Pros

- Stillness detection is a useful fit for occupancy-triggered lighting where PIR-only movement detection may switch lights off while someone is seated.
- Battery operation avoids needing a power cable at the sensor location.
- Local SwitchBot linkage without a hub is described for up to two automations.

## Cons

- The expanded smart-home integrations and more complex scenarios depend on a separately sold SwitchBot hub.
- Detection distance depends on whether the person is moving or stationary, so the listed maximum range should not be treated as a single usable range for every situation.

## Before you buy

- The listing is inconsistent about quantity and battery life: the title says 2-Pack while the explicit contents list says Presence Sensor × 1, the item count says 1 and the pack count says 2. Battery life is listed as 3 years in details but described as up to 2 years in the feature text. It also gives a maximum range of 393 Feet alongside specific ranges of up to 8 m for moving people and 5 m for stationary people. Confirm the selected listing's sensor quantity and applicable range and battery-life claims before buying.

## In the box

- Presence sensor × 1 (Included): The explicit contents list specifies one, despite the title describing a 2-pack. Confirm bundle quantity on the selected listing.

## A good fit for

- People automating lights in rooms where someone may sit still, such as a reading area or home office.
- Existing SwitchBot users wanting battery-powered presence sensing and basic local device linkage.
- Buyers who can use a SwitchBot Hub for the more complex automations or ecosystem integrations they need.

## Less suited to

- Buyers needing a confirmed two-sensor bundle without checking the seller's selected listing.
- People who require hub-free Matter or Apple Home integration.
- Installations that depend on one confirmed, unconditional detection distance or battery-life figure.

## Customer feedback

Customer feedback describes good presence detection, including detecting someone still in a room, and reports straightforward setup, useful positioning and good battery life. Some customers also report connection issues. These impressions are relevant if you want stillness-based lighting automation, but do not resolve the listing's conflicting package quantity, battery-life claims or detection ranges.
- Positive themes: Customers report effective presence detection, including while someone remains still.
- Positive themes: Feedback notes easy setup, battery life and flexible positioning.
- Negative themes: Some customers report connection issues.
- Mixed feedback: Connectivity is described as straightforward by some customers, while others report problems.

## Frequently asked questions

### Does the listing confirm that two sensors are included?
No. The title says 2-Pack, but the contents list names one Presence Sensor and the item count is also one. Check the selected listing's package details before ordering.
### Can it detect someone who is sitting still?
The listing says its mmWave and PIR sensing can detect subtle chest movements from stationary people, and gives a separate 5 m range for stationary humans.
### Is a hub required?
The listing says basic SwitchBot device linkage works without a hub, with up to two automations. A SwitchBot Hub is required for more complex scenarios and is named as necessary for the described Matter integrations.
### How long does the battery last?
The details list 3 years, while a feature claim says up to 2 years on a single charge. These claims conflict, so treat battery life as unconfirmed for the selected listing.
