SwitchBot Thermometer Hygrometer Meter Plus x2 + Hub Mini — Bluetooth indoor temp & humidity, 3″ display

The SwitchBot Thermometer Hygrometer Meter Plus bundle delivers precise, app-connected temperature and humidity tracking with a large, easy-to-read display and long-term data logging.

This compact Bluetooth sensor pair (Meter Plus x2 plus Hub Mini) is built for indoor climate monitoring: fast, Swiss-made sensing, a bold 3-inch screen, and cloud-capable history when connected to the Hub Mini. It reports environmental changes quickly, stores weeks of local logs, and pushes alerts to your phone so you can check conditions anywhere. Use it on shelves, magnetic surfaces, or mounted on walls for continuous oversight of living spaces, greenhouses, wine cellars, or kitchens.

How accurate are the Meter Plus sensors and how quickly do they update?

The Meter Plus units use a Swiss-made sensor that measures temperature and humidity with high precision and frequent sampling. Temperature accuracy is maintained to about ±0.2°C (±0.4°F) across a broad range, and humidity is accurate to ±2%RH. Readings are refreshed multiple times per second so you’ll capture rapid changes in your environment.

• Swiss-made sensor for reliable baseline readings
• Temperature range: -20°C to 80°C (-4°F to 176°F)
• Humidity range: 0–99%RH with ±2%RH accuracy
• High-frequency sampling to track fast fluctuations

What will I see on the large display and how is it useful daily?

The Meter Plus has a bold 3-inch screen that shows temperature, humidity, and practical icons to highlight whether your room is inside your custom comfort or storage thresholds. The larger digits make it effortless to glance at current conditions from across a room, and simple icons indicate dew point or VPD states when enabled.

• 3-inch display with clear temperature and humidity readouts
• Visual icons for quick status (comfort, too dry, too humid, etc.)
• Three-angle stand, wall mount, or magnetic attachment options
• Easy unit switch between Celsius and Fahrenheit

How does data storage, export, and remote alerts work with the Hub Mini?

Without a Hub, each Meter Plus stores up to 68 days of on-board data and lets you view historical charts in the SwitchBot app. Adding the Hub Mini extends data storage to two years in the app and enables unlimited cloud storage, remote push notifications, and CSV export for analysis. Remote alerts can be used to trigger scenes or notify you if conditions cross your custom thresholds.

• 68 days local on-device storage per sensor
• Up to 2 years in-app history; unlimited cloud with Hub connected
• CSV export for deeper analysis and record keeping
• Push notifications and automation scenes via Hub Mini

Where is this sensor most useful and how can I install it?

The Meter Plus is versatile for household and specialty spaces: maintain ideal humidity for wooden furniture, monitor a wine cellar, keep seedlings healthy in a greenhouse, or prevent damp in basements. Installation is flexible — place it on a tabletop at three different angles, mount it to a wall, or attach it to metal surfaces with its magnetic backing.

• Suitable for wine cellars, greenhouses, kitchens, basements, and nurseries
• Tabletop stand in three tilt angles for optimal viewing
• Wall-mount and magnetic rear for permanent placement
• Works as paired sensors to monitor multiple rooms simultaneously

Who is this for: The SwitchBot Meter Plus bundle with Hub Mini suits homeowners, plant growers, and anyone who needs dependable indoor climate data and alerts. It’s a good fit if you want a visible, fast-reading display in multiple locations plus robust historical logging and remote notifications for peace of mind or precise environmental control.
