SONOFF Temp./Humidity Sensor SNZB-02DR2 – Smart Home Climate Monitoring for Every Room
The SONOFF SNZB-02DR2 is a Zigbee-based temperature and humidity sensor with a built-in LCD display, sold as a 2-pack. It measures ambient temperature and relative humidity in real time and transmits the data wirelessly to the eWeLink app for centralized smart home monitoring.
Real-time temperature and humidity readings on a built-in LCD display for instant, at-a-glance monitoring
Zigbee wireless protocol ensures low-power, stable communication with the eWeLink hub and other Zigbee devices
2-pack configuration allows monitoring in two rooms or positions simultaneously — ideal for bedrooms, living areas, or utility spaces
Compact, white design blends discreetly into any room setting without visual clutter
What makes the SONOFF SNZB-02DR2 stand out
Unlike basic sensors that require a separate display unit or app-only readings, the SNZB-02DR2 provides on-device LCD feedback so you can check current conditions at a glance without opening your phone. The Zigbee protocol keeps power consumption low, enabling long battery life while maintaining a reliable wireless connection to the eWeLink ecosystem.
Ideal for
Homeowners and renters who want to track indoor climate conditions across multiple rooms without relying solely on a smartphone. The 2-pack format suits households that need simultaneous monitoring in different zones — for example, a bedroom and a nursery, or a living room and a basement.
Application of the SONOFF SNZB-02DR2
Place each sensor in the room you want to monitor — on a shelf, a desk, or a bedside table. The LCD display shows the current temperature and humidity reading instantly. Data is transmitted via Zigbee to the eWeLink app, where you can view historical trends, set threshold alerts, and integrate the sensors into broader smart home automations such as triggering a humidifier or ventilation fan when humidity exceeds a set level.
SONOFF is a smart home brand specializing in wireless sensors and monitoring devices. The brand focuses on Zigbee and Wi-Fi connected products that integrate with the eWeLink ecosystem, offering climate, motion, and door/window sensors for residential and commercial smart home setups.
The sensor measures ambient temperature and relative humidity in real time, displaying readings on the built-in LCD screen and transmitting them wirelessly to the eWeLink app.
The sensor works with the eWeLink app via the Zigbee wireless protocol. It requires a Zigbee-compatible hub (such as the SONOFF Zigbee Bridge) connected to the eWeLink app for full functionality.
The package contains two identical SNZB-02DR2 temperature/humidity sensors with LCD displays, each with its own battery. No additional hub or bridge is included.
Each sensor runs on a built-in battery (power consumption is low due to the Zigbee protocol). Battery replacement is needed when the display indicates low power or readings stop updating.
Yes, both sensors can be placed in the same room or in different rooms. The eWeLink app supports adding multiple sensors and assigning them to specific locations for organized monitoring.
