Data from the official Sonoff and X-Sense sites.
2026 verdict
If the reading has to live on the sensor, the Sonoff SNZB-02WD wins this pairing against the X-Sense STH0B Smart Thermometer Hygrometer.
The Sonoff SNZB-02WD has an LCD and an IP65 shell, joins a Zigbee coordinator, and reaches Google Home, Alexa, SmartThings, Home Assistant and Apple Home and Matter through a Sonoff bridge. The X-Sense STH0B Smart Thermometer Hygrometer has no screen and cannot report anything without an X-Sense SBS50 base station, but it answers with a long 868 MHz link, dew point and VPD history with CSV export, and a lower price. Buy the Sonoff SNZB-02WD for a readable, weather-rated sensor on a hub you already own, and the X-Sense STH0B Smart Thermometer Hygrometer only when an X-Sense base station is already installed and the sensor sits far from it.

What the differences mean
Screen
The Sonoff SNZB-02WD has an LCD that shows temperature and humidity directly on the device. The X-Sense STH0B Smart Thermometer Hygrometer has only a red and blue indicator light, so every reading is opened in the X-Sense app.
Radio and hub
The Sonoff SNZB-02WD is a Zigbee end device that joins any coordinator. The X-Sense STH0B Smart Thermometer Hygrometer talks a proprietary 868 MHz link to an X-Sense SBS50 base station, rated up to 500 m in the open, and works with nothing else.
Weather rating
The Sonoff SNZB-02WD is IP65 rated for damp and sheltered outdoor spots. The X-Sense STH0B Smart Thermometer Hygrometer is not waterproof and its manual advises against long term use above 80% RH.
Platforms
The Sonoff SNZB-02WD reaches Alexa, SmartThings, Home Assistant and, through a Sonoff bridge, Apple Home and Matter. The X-Sense STH0B Smart Thermometer Hygrometer ends at Alexa and a community Home Assistant integration, with no Google Home, Apple Home, SmartThings or Matter.
History and derived data
The X-Sense STH0B Smart Thermometer Hygrometer app keeps 24/7 graphs with dew point and VPD and exports up to 180 days per CSV file. The Sonoff SNZB-02WD app graphs temperature and humidity without the derived figures.
Which one to buy if
- you want the number on the device
The Sonoff SNZB-02WD has an LCD, where the X-Sense STH0B Smart Thermometer Hygrometer has no screen at all.
- you already run an X-Sense SBS50 base station
The X-Sense STH0B Smart Thermometer Hygrometer drops onto that base station and adds dew point, VPD and CSV export to the app you already use.
- the sensor goes in a damp spot
The Sonoff SNZB-02WD is IP65 rated, while the X-Sense STH0B Smart Thermometer Hygrometer is not waterproof.
- you want the longest reach from the base
The X-Sense STH0B Smart Thermometer Hygrometer uses an 868 MHz link rated up to 500 m in the open, further than a typical Zigbee hop.

What owners say
Owners of the Sonoff SNZB-02WD praise the IP65 shell and the LCD that lets them read temperature and humidity on the device in a greenhouse, a garage or a bathroom, and they describe pairing with ZHA and Zigbee2MQTT as fast and reliable. The magnetic, screw-secured battery door is called an improvement over older Sonoff sensors, and several report the battery still reading full after months. Their complaints are that it is Zigbee only and needs a hub, that Apple Home works only through a SONOFF Matter bridge, that the reporting interval feels slow for some monitoring, and that it uses a less common CR2477-style cell.
Frequently Asked Questions
Which is better overall: Sonoff SNZB-02WD or X-Sense STH0B Smart Thermometer Hygrometer?
The Sonoff SNZB-02WD for most buyers. It has a screen, an IP65 rating and support for more platforms. The X-Sense STH0B Smart Thermometer Hygrometer is the better add-on only when an X-Sense SBS50 base station is already installed and you need reach far from the router.
What is the biggest difference between the Sonoff SNZB-02WD and the X-Sense STH0B Smart Thermometer Hygrometer?
A screen and a Zigbee radio versus a base-station-only probe. The Sonoff SNZB-02WD shows its readings on an LCD and joins any Zigbee coordinator, while the X-Sense STH0B Smart Thermometer Hygrometer has no screen and cannot report without its X-Sense base station.
Does the X-Sense STH0B Smart Thermometer Hygrometer have a screen?
No. The X-Sense STH0B Smart Thermometer Hygrometer has only a red and blue indicator light, and every reading, graph and alert is viewed in the X-Sense app.
Is the Sonoff SNZB-02WD waterproof?
It carries an IP65 weather-resistance rating, making it suitable for greenhouses, garages, bathrooms and sheltered outdoor spots. It still needs a Zigbee hub to report.
Which one works with more smart home platforms?
The Sonoff SNZB-02WD. It reaches Alexa, SmartThings and Home Assistant, and Apple Home and Matter through a Sonoff bridge. The X-Sense STH0B Smart Thermometer Hygrometer supports only Alexa and a community Home Assistant integration.
Does the X-Sense STH0B Smart Thermometer Hygrometer work without its base station?
No. The X-Sense STH0B Smart Thermometer Hygrometer has no Wi-Fi of its own and communicates over a proprietary 868 MHz radio, so an X-Sense SBS50 base station is required before it reports anything.
