Sonoff SNZB-02LD Smart Zigbee Temperature Sensor with Probe and Display

Sonoff SNZB-02LD Smart Thermometer with Temperature Monitoring Probe

The Sonoff SNZB-02LD is a Zigbee 3.0 smart temperature sensor featuring a 2.2" LCD display and a

1.5 meter external stainless steel probe , designed for precise measurements even in difficult to reach environments

reach. Thanks to the IP65 waterproof structure, UV-resistant materials and compatibility with

eWeLink app , this smart thermometer is ideal for professional and home monitoring

of temperature in liquids, tanks, refrigerators , greenhouses, aquariums, closed environments and much more.

Precise Monitoring Even in Extreme Environments

The food grade 304 stainless steel probe allows you to detect the temperature in liquids or closed spaces,

offering an effective solution where normal sensors do not reach. The sensor is able to work

correctly in a temperature range between -20°C and +60°C , with an accuracy of ±0.2°C.

eWeLink App: Monitoring, Notifications and Data History

Through the eWeLink app, you can check the temperature in real time, view detailed graphs by day,

month or semester, and export up to 180 days of history . Receive instant notifications and in case of abnormal changes

and create intelligent automations , such as turning on a refrigerator or heater when a predefined threshold is exceeded.

Intelligent Automation and Local Operation

Thanks to the Local Smart Scene function, automations work even without a Wi-Fi connection,

using the Zigbee network . You can monitor whether the refrigerator temperature exceeds the set threshold, avoiding the

food spoilage. Aquarium Check : If the water temperature drops below the ideal level,

The sensor automatically activates the heater connected to a ZBMini R2 to protect the fish.

2.2" LCD display with Comfort Indication

The high-readability LCD screen shows the temperature in real time, in °C or °F (with automatic switching based on the

eWeLink region), and intuitive environmental comfort icons that indicate whether the environment is too hot, too cold or optimal.

Wide Zigbee 3.0 Compatibility

The Sonoff SNZB-02LD requires a Zigbee 3.0 gateway to connect to the App and function properly.

It is compatible with: SONOFF NSPanel Pro , SONOFF iHost , SONOFF ZB Bridge Pro , Sonoff Bridge Ultra ,

SONOFF ZBDongle-E , Echo Plus 2nd Gen, Echo Show 2nd Gen, Home Assistant via Zigbee2MQTT or ZHA.

Voice Control with Smart Platforms

You can connect the SNZB-02LD sensor to a compatible Zigbee hub and, via the eWeLink app, pair it with voice platforms such as

Google Home, Amazon Alexa, SmartThings, and IFTTT . You can control and automate every aspect of your home environment.

Simply ask “What is the temperature of the tub?” and get the answer in real time, without having to touch a thing.

Zigbee: The Ideal Choice for Smart Sensors

Compared to Wi-Fi, the Zigbee protocol is perfect for low-power devices such as environmental sensors. It reduces the

response times, improves energy efficiency , and supports reliable communications even without an Internet connection.

The Sonoff SNZB-02LD takes full advantage of this potential, becoming a key element of your home automation ecosystem.

Battery Powered & Versatile Installation

The Sonoff SNZB-02LD is powered by a CR2477 battery , ensuring long battery life and flexible installation without

the need for power supply. It can be placed anywhere thanks to the magnetic base , lanyard hole and adhesive backing.
