2026 verdict
Outdoors or in a damp spot, the Sonoff SNZB-02WD is the better of these two Sonoff Zigbee sensors, since it is IP65 rated and the Sonoff LCD Smart Temperature Humidity Sensor is indoor only.
The Sonoff SNZB-02WD also carries the longer warranty, 2 years against 1, and is the better reviewed of the two, and it has an LCD, pairs easily through ZHA or Zigbee2MQTT and keeps history. The Sonoff LCD Smart Temperature Humidity Sensor is the lower priced one and documents more: a 2 year battery rating on a CR2450, low-battery alerts and Google Home support, none of which is documented for the Sonoff SNZB-02WD. Both need a Zigbee hub, and both reach Apple Home and Matter only through a SONOFF hub. Choose the Sonoff SNZB-02WD for garages, greenhouses and log stores, and the Sonoff LCD Smart Temperature Humidity Sensor for ordinary indoor rooms at a lower price.

What the differences mean
Weather resistance
The Sonoff SNZB-02WD is rated IP65, so a garage, a greenhouse or a covered outdoor spot is fair game. The Sonoff LCD Smart Temperature Humidity Sensor has no weather rating and is indoor only, which is the difference that decides where each one can live.
Screen
Both have an LCD that shows temperature and humidity on the device. The Sonoff LCD Smart Temperature Humidity Sensor has a 2.5 inch panel and the Sonoff SNZB-02WD a 2.2 inch one, a small gap that matters only if you read the sensor from across a room.
Battery and alerts
The Sonoff LCD Smart Temperature Humidity Sensor runs on a common CR2450 with a documented 2 year rating and adds a low-battery alert. The Sonoff SNZB-02WD takes a less common CR2477 and its battery life and low-battery alerts are not documented, so the Sonoff LCD Smart Temperature Humidity Sensor is the more predictable one to keep running.
Warranty and size
The Sonoff SNZB-02WD carries a 2 year warranty against 1 year for the Sonoff LCD Smart Temperature Humidity Sensor. The two are close in size, 62.8 x 58.5 x 21.8 mm and 65.6 g for the Sonoff SNZB-02WD, and 59.5 x 62.5 x 18.5 mm and 69.5 g for the Sonoff LCD Smart Temperature Humidity Sensor.
Platforms
Both work with Alexa, SmartThings and Home Assistant, and both reach Apple Home and Matter only through a SONOFF hub. Google Home support is listed for the Sonoff LCD Smart Temperature Humidity Sensor and not documented for the Sonoff SNZB-02WD.

What owners say
Owners of both Sonoff sensors agree on the essentials: an LCD they can read without opening an app, and Zigbee pairing with Home Assistant, through ZHA or Zigbee2MQTT, that takes seconds. Sonoff SNZB-02WD owners single out the IP65 shell that lets them use it in garages, greenhouses, log stores and bathrooms, and the magnetic, screw-secured battery door, and they mention strong battery performance. Sonoff LCD Smart Temperature Humidity Sensor owners like the sharp 2.5 inch screen and the built-in kickstand, and use its thresholds to switch fans or dehumidifiers. On the complaint side, Sonoff SNZB-02WD owners mention a reporting interval that feels slow and an uncommon CR2477-style cell, while a minority of Sonoff LCD Smart Temperature Humidity Sensor owners report display or connection problems on individual units and battery drain at frequent reporting intervals.
