## At a glance

- Measures temperature and humidity, with the app also supporting dew point, VPD and absolute humidity readings.
- Bluetooth viewing is claimed up to 100 metres when there are no obstacles.
- Stores up to 68 days of readings on-device and up to two years in the app. CSV export is supported.
- Hub-dependent features include preset-value push notifications and unlimited cloud storage.

## Pros

- Three sensors can help monitor separate locations such as a greenhouse, refrigerator or instrument case.

## Cons

## Before you buy

- The listing gives conflicting physical details: dimensions are listed as 20W x 60H millimetres, while another product description gives 60×28×20 mm. It also describes a Lithium-Polymer battery in the details but specifies 2 x AAA in another section and 6\*AAA \(built-in\) in the included-components list. Confirm the selected listing's dimensions and battery arrangement before buying. The claimed accuracy and range are manufacturer statements, not independently established measurements.

## In the box

- 3 outdoor meters (Included)
- User manual (Included)
- 6 AAA batteries, listed as built-in (Included): The battery type and arrangement conflict with other listing details.
- 3 lanyards (Included)

## A good fit for

- People wanting multiple temperature and humidity sensors for locations such as a greenhouse, refrigerator or cellar.
- Users who want to export readings and inspect temperature or humidity changes over time.
- Existing SwitchBot users who can add a Hub for remote notifications and unlimited cloud storage.

## Less suited to

- Buyers who need remote alerts or unlimited cloud storage without adding a SwitchBot Hub.
- Anyone requiring guaranteed Bluetooth coverage through walls or at the full stated range.

## Customer feedback

Customer feedback highlights ease of setup, portability, temperature tracking and perceived accuracy, with positive comments about usability and value. Bluetooth experiences are mixed, so the claimed 100-metre range should not be treated as assured in every setting. These reported impressions are relevant to a three-sensor Bluetooth monitoring kit, but do not establish measurement accuracy or connection performance for every installation.
- Positive themes: Customers report straightforward setup, portability and useful temperature tracking over time.
- Positive themes: The feedback summary describes positive impressions of accuracy, ease of use and value.
- Mixed feedback: Bluetooth connectivity receives mixed feedback, with some reporting issues and others reporting no problems.
