2026 verdict
Two Sonoff Zigbee sensors, one question: do you want a screen and a sealed body?
If so, the Sonoff SNZB-02WD is the better temperature and humidity sensor of the pair, with an IP65 rating and an LCD that shows the reading without an app. The Sonoff SNZB-02P Temperature & Humidity Sensor is the plainer, cheaper one, rated for 4 years on its battery, with low-battery alerts and a Google Home listing, and it is the pick for dry indoor rooms. Both need a Zigbee hub and both work with Alexa, SmartThings and Home Assistant. Choose the Sonoff SNZB-02WD for garages, greenhouses and glance-and-go readings, and the Sonoff SNZB-02P Temperature & Humidity Sensor for quiet indoor monitoring.

What the differences mean
Screen
The Sonoff SNZB-02WD has a built-in LCD. The Sonoff SNZB-02P Temperature & Humidity Sensor has no display, so its readings only show in an app or dashboard.
Weather resistance
The Sonoff SNZB-02WD is rated IP65 and is at home in damp or outdoor spots. The Sonoff SNZB-02P Temperature & Humidity Sensor is not weather resistant and is for indoor use only.
Battery
The Sonoff SNZB-02P Temperature & Humidity Sensor uses a CR2477 rated for 4 years and sends low-battery alerts. The catalog does not document the battery type or life of the Sonoff SNZB-02WD, and it does not list low-battery alerts for it.
Google Home
The Sonoff SNZB-02P Temperature & Humidity Sensor lists Google Home support. It is not documented for the Sonoff SNZB-02WD, so Google Home households should check before buying it.
Same platform story otherwise
Both work with Alexa, SmartThings and Home Assistant, and both reach Apple Home and Matter only through a SONOFF hub, so the choice is about where the sensor lives, not which ecosystem it joins.

What owners say
Owners of both Sonoff sensors describe easy pairing with Home Assistant through ZHA or Zigbee2MQTT and a device that stays reliable once connected. Sonoff SNZB-02P Temperature & Humidity Sensor owners like the magnetic mount, the battery that goes years between changes and how well it works with Echo devices that have a built-in Zigbee hub, and a small share report pairing trouble with particular hubs. Sonoff SNZB-02WD owners use it in garages, greenhouses and log stores, like reading the value straight off the LCD, and mention strong battery performance and a more secure battery door. Their main criticism is a reporting interval that feels slow when you need quick updates.
