SwitchBot MeterTH S1 - Temperature and humidity sensor, White

The SwitchBot MeterTH S1 Thermometer and Hygrometer is a digital sensor designed for monitoring indoor climate conditions. It relies on a Swiss Sensirion component to measure temperature and humidity, displaying readings on a built-in LCD screen. Temperature accuracy is rated to ±0.2 °C, enabling reliable tracking in sensitive environments. When paired with the SwitchBot app, the device also calculates dew point and VPD. This functionality suits specific use cases like wine cellars, greenhouses, and terrariums. Local data transfers to iOS and Android devices over a 2.4 GHz Bluetooth link.

Remote access, data logging, and CSV export require a separate SwitchBot Hub. Adding the hub also enables smart home integration with Amazon Alexa, Google Assistant, and Apple Home. Two included AAA alkaline batteries provide up to one year of power, with an on-screen indicator signalling low charge. Installation accommodates freestanding or adhesive mounting on indoor surfaces. A physical reset button is present for troubleshooting. The unit communicates exclusively via Bluetooth and does not support direct Wi-Fi connections.
