◆ Zigbee 3.0 Smart Temperature Sensor with LCD Display and Probe — this unit is not a motion or motion-light sensor. It’s a thermometer sensor designed for smart climate monitoring with an external probe for measuring temperatures in hard-to-reach or harsh environments.
🔥 Key Verified Features
✔ Zigbee 3.0 Connectivity
Connects to compatible Zigbee hubs (Sonoff ZBBridge, iHost, ZBDongle, NSPanel Pro, etc.) for smart readings and automations.
✔ External Stainless-Steel Probe (1.5 m)
Allows temperature measurement in liquids, tanks, refrigerators, freezers, pools, and other enclosed or tough spaces.
✔ 2.2″ LCD Screen
Shows real-time temperature readings directly on the device without needing a phone.
✔ IP65 Water & Dust Resistance
Safe for splash-prone and humid environments — ideal for bathrooms, outdoors, or kitchens.
✔ Long Battery Life (CR2477)
Operates on a replaceable CR2477 battery with up to ~2 years of typical life.

📌 What It Is & Is Not
✅ It IS
• A Zigbee temperature sensor with LCD and external probe
• A device for real-time and app-based temperature monitoring
• Capable of automations based on temperature thresholds
❌ It IS NOT
• A motion detector
• A light or presence sensor
• A humidity sensor (this model itself measures temperature only — not humidity)
🎯 How It Works in Smart Home
• Pair the SNZB-02LD with a Zigbee hub/coordinator (e.g., Sonoff ZBBridge, iHost, ZBDongle series).
• Use the eWeLink app to view temperature readings remotely, set alerts, and trigger automations (e.g., turn on a heater if temperature drops below threshold).
• The probe allows accurate temperature sampling in liquids or internal spaces where the main unit cannot reach.
📍 Typical Use Cases
✔ Monitoring water tank temperature
✔ Checking refrigerator/freezer environment
✔ Greenhouse / gardening temperature data
✔ Outdoor or humid area temperature tracking
✔ Aquariums and pet habitats
