YoLink Smart Freezer Thermometer 3-Pack | LoRa Wireless Temperature Sensor with App Alerts

Overview

Meet the YoLink Smart Freezer Thermometer, a 3-pack of LoRa-based temperature sensors designed for flexible placement without relying on WiFi. These compact sensors suit refrigerators, freezers, greenhouses, and pet enclosures, helping you stay aware of environmental changes without constant handholding.

Powered by YoLink's LoRa network, the sensors communicate over a long-range, low-power protocol. In open air, a sensor can cover up to a quarter mile when connected to the YoLink hub, so you can position devices where WiFi is spotty or unavailable and still receive timely updates in the YoLink app.

Real-time monitoring and alerts

• Temperature monitoring with regular updates to the YoLink app helps you keep spaces within your preferred range.
• Customizable thresholds let you set triggers for temperature changes, with alerts delivered by text, email, or push notifications. SMS allowances apply per device.

Apple users can enable Critical Alerts to bypass silent mode for urgent notices. Android users enjoy similar options, ensuring important readings are visible when it matters most.

Power, maintenance, and reliability

• Battery-powered with two AA batteries, the sensor is designed for up to five years of operation, depending on usage and environment.
• Real-time low-battery alerts help you plan replacements before issues arise, keeping monitoring uninterrupted in hard-to-reach locations.

The sensor operates independently of your WiFi network, offering dependable monitoring even during network disruptions and reducing congestion on your home network.

Integrations and control

With IFTTT and Alexa compatibility, you can trigger applets or query temperature through voice. Note that Alexa routines are not supported at this time.

Specifications at a glance

The thermometer delivers commercial-grade accuracy: about ±0.36°F from 32°F to 129°F, and ±0.72°F from -20°F to 32°F. The measurable range spans -4°F to 129°F (-20°C to 54°C), supporting a variety of environments from cool to warm.

Getting started

A YoLink hub is required for full functionality, including app access and alerts. The 3-pack gives you multiple sensing points for comprehensive coverage across refrigerators, freezers, greenhouses, barns, and more. Pair sensors to the hub, customize alerts, and monitor from the app with optional SMS alerts.

Real-world use cases

Use one sensor inside a refrigerator for perishables, another in a freezer for cold storage, and a third in a greenhouse or animal enclosure to monitor climate. The LoRa network enables far-flung monitoring without overloading your WiFi.
