The SONOFF SNZB-02D is a Zigbee 3.0 temperature/humidity sensor with a 2.5‑inch LCD and CR2450 coin battery. Specific attributes: a 2.5-inch black & white display plus a Silicon Labs Zigbee SoC; temperature accuracy ~0.2°C and humidity ~±2–5% (calibration supported). Good for local display and Home Assistant/Zigbee2MQTT integration, but expect occasional reporting hangs and the need to calibrate humidity for accurate readings.
Buy if you want a Zigbee sensor with a readable local LCD and Home Assistant integration; avoid if you need rock‑solid, maintenance‑free remote reporting.
