SwitchBot Bluetooth Hygrometer Thermometer — 3x IP65 Outdoor Sensors + Hub Mini, Swiss Sensor & 394 ft Bluetooth Range

The SwitchBot Bluetooth Hygrometer Thermometer kit is a weatherproof temperature and humidity monitoring system with high-precision Swiss sensor, remote app control, and a Hub Mini for voice and cloud access.

Keep reliable environmental data for rooms, outdoor spaces, and specialty containers with this kit that includes three IP65 sensors and a SwitchBot Hub Mini. Each sensor measures temperature and relative humidity quickly and accurately, logs data locally and to the cloud, and alerts you when conditions move beyond your set thresholds. The Hub Mini bridges the sensors to the internet for remote viewing, voice assistant compatibility, and long-term storage.

How accurate and fast are the readings?

The SwitchBot sensors use industrial-grade Swiss Sensirion elements to deliver precise measurements and quick sampling. Expect accuracy typical for high-end consumer monitors and updates every few seconds so you can spot rapid changes in environment.

• Sensor: Swiss Sensirion industry-grade sensor
• Accuracy: ±1.8% RH for humidity, ±0.2°C (±0.36°F) for temperature
• Sampling interval: about every 4 seconds for real-time tracking
• Supports dew point, VPD, and absolute humidity readings

Can I use these outdoors and in wet places?

Yes—the sensors are rated IP65, so they resist dust and water spray, making them suitable for covered outdoor spots, greenhouses, and damp indoor areas. Avoid full submersion; the IP65 rating protects against rain and splashes rather than immersion.

• IP65 dustproof and splash-resistant enclosure
• Lightweight, portable design for varied placements
• Suitable for patios, basements, bathrooms, and refrigerators
• Not intended for continuous underwater use

How do I view, store, and export my sensor data?

Connect sensors to the SwitchBot app via Bluetooth or use the included Hub Mini to sync data to the cloud for remote access. The device keeps up to 68 days of local logs, two years in the app, and unlimited cloud storage when linked—ideal for long-term trend analysis.

• Local storage: up to 68 days on-device
• App storage: up to 2 years with visual charts (hourly to yearly)
• Cloud: unlimited storage when using the Hub Mini and account
• Export: CSV files for external analysis and record-keeping

What smart features and alerts are available?

The kit delivers customizable push notifications and supports voice control through major smart assistants when paired with the Hub Mini. Set thresholds for temperature, humidity, dew point, or VPD and get instant alerts to protect plants, instruments, food storage, or animal habitats.

• Instant app notifications when values exceed presets
• Voice queries and control via Alexa, Google Home, Siri Shortcuts, SmartThings
• Multiple calibration options to fine-tune readings
• Scene conditions available for dew point and VPD monitoring

Who this is for: This SwitchBot kit suits hobbyists and professionals who need dependable environmental monitoring across multiple locations—gardeners, wine and humidor caretakers, pet and reptile owners, musicians storing instruments, and homeowners tracking humidity-sensitive spaces. It’s for anyone who wants quick sampling, reliable alerts, and cloud access plus voice convenience without complex installation.
