Thermometer and Hygrometer Plus SwitchBot W2301500 — temperature and humidity sensor, Bluetooth

SwitchBot Thermometer and Hygrometer Plus is a compact Bluetooth temperature and humidity sensor designed for monitoring indoor climate in homes and offices. The device reports current temperature and relative humidity, stores recent measurements locally, and connects to the SwitchBot ecosystem for remote reading and data access. Its small size allows placement on shelves, near plants, in cabinets or on walls to track environmental conditions in climate-sensitive rooms.

Advantages

The sensor provides continuous measurement of temperature and relative humidity with local storage of recent data and Bluetooth connectivity for easy pairing with SwitchBot devices and the mobile app. Its compact build supports discrete placement while offering reliable readings for routine indoor monitoring. Integration with SwitchBot systems enables remote access and use in automated scenarios when combined with other SwitchBot products.

Suitable for

• Monitoring living rooms, bedrooms and home offices for comfort control
• Tracking humidity and temperature in plant rooms, greenhouses or terrariums
• Checking HVAC performance and verifying temperature-sensitive storage areas
• Placing in cabinets, wine storage, or instrument rooms where stable climate is needed

Key specifications

• Measurement parameters: ambient temperature and relative humidity
• Connectivity: Bluetooth for local data transmission to smartphone app and SwitchBot hub
• Data storage: stores recent measurements for on-device retrieval
• Form factor: compact, wall-mountable or tabletop placement options
• Power: battery-powered for flexible placement (check user manual for battery type and replacement guidance)

How to use

Place the Thermometer and Hygrometer Plus in the area where you want to monitor conditions, avoiding direct sunlight and sources of heat or moisture that could skew readings. Power the device according to the included instructions and pair it with the SwitchBot mobile app using Bluetooth. Once paired, the app displays current readings and recent stored data; if you use a SwitchBot hub, enable remote access to view measurements when away from the local Bluetooth range. For best results, allow the sensor to stabilize in its environment for a few minutes before relying on readings.

Usage recommendations

Install the sensor at breathing height for living spaces (about 1–1.5 m) and away from windows, vents or doors to obtain representative indoor measurements. For plant or storage monitoring, position the device near but not touching the monitored object. Regularly check battery status and app firmware updates to ensure continuous and accurate monitoring.
