SONOFF SNZB-02WD IP65 Outdoor Zigbee Temperature & Humidity Sensor

SONOFF's newest outdoor-rated climate sensor, built for UK conditions. The IP65-rated housing with a breathable membrane keeps rain and condensation out while giving accurate temperature and humidity readings from outside — garden, shed, greenhouse, garage, or a north-facing wall.

The built-in LCD shows the current reading directly on the sensor, so you don't need to check your phone to see what the garden is doing. Reports to your hub every few minutes and supports historical logging. Swiss-grade Sensirion sensor inside, ±0.2°C accuracy.
