Description
The SONOFF SNZB-02LD is an IP65 Zigbee 3.0 smart thermometer with a clear 2.2-inch LCD display and a 1.5 m temperature probe. The probe measures from -40°C to 115°C, so you can take accurate readings in liquids or enclosed spaces such as fridges, freezers and aquariums that standard sensors cannot reach.
Use the eWeLink app to view temperature data by day, month or up to six months, export historical charts for detailed analysis, and create alerts and Zigbee automations based on temperature changes. It runs on a CR2477 coin cell battery.
Note: a Zigbee 3.0 gateway is required (see "Works With" below). The IP65 rating is for splash-proof use: avoid submerging the device, exposing it to high-pressure water jets, or placing it outdoors where it may be exposed to rain.
