## Long description

SONOFF SNZB-02LD IP65 Zigbee LCD Smart Thermometer (Probe Version) combines a 2.2″ LCD display with a 1.5 m stainless steel probe to measure temperature in liquids, tanks, fridges and enclosed spaces. The probe transmits readings via Zigbee 3.0 to compatible hubs and can be used for local automation and historical data logging.
Advantages
The IP65-rated housing provides splash protection for wet or demanding environments. The large LCD shows real-time probe temperature from –40 °C to +115 °C. Zigbee 3.0 ensures compatibility with many smart home hubs and supports local automation. The device stores up to 180 days of history in the app with export options, and it is powered by a CR2477 coin-cell battery for straightforward maintenance.
