Accurate Measurements with the External Probe

The 1.5-meter probe, made of food-grade 304 stainless steel, allows for precise temperature monitoring in liquids such as pool or aquarium water, as well as in enclosed spaces like a refrigerator or terrarium.

Quick Installation

The built-in magnet and holder allow for mounting on metal surfaces or hanging.

Data History and Smart Automations

With the eWeLink app, you have access to measurement history from the last 180 days in the form of clear graphs. Set up smart scenes to automatically control other devices (e.g., heating, fans) based on temperature readings.

Wide Compatibility with Smart Home Systems

The sensor is compatible with Zigbee 3.0 gateways such as SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBDongle-E, as well as platforms like Amazon Alexa, Homey PRO, and open-source systems like Home Assistant (via ZHA or Zigbee2MQTT).
