Description
xOverview
The YoLink Smart Freezer Thermometer 3-Pack brings reliable temperature monitoring without relying on your WiFi. Using a LoRa-based protocol, these sensors talk over a long-range, low-power network, so you can place them in spots where WiFi doesn’t reach—from deep in a fridge to a greenhouse or barn—without slowing down your home network.
With precise readings and real-time updates, you’ll have a clear view of environmental conditions wherever you need them. The system is designed to be practical, not pushy—alerts appear when you want them, and you decide how you’d like to be notified.
Key connectivity and performance
- LoRa > WiFi: ultra-long-range, low-power communication that avoids crowding your home network. Typical range can extend up to 1/4 mile in open air.
- Wide temperature coverage: from -4°F to 129°F (-20°C to 54°C) to accommodate coolers, warm rooms, and more.
- Commercial-grade accuracy: ±0.36°F (32°F to 129°F) and ±0.72°F (-20°F to 32°F) for dependable readings across environments.
- Battery-powered longevity: two AA batteries power the sensor for up to 5 years depending on use and conditions.
Alerts, notifications, and automation
- Customizable thresholds: set temperature limits and receive alerts when conditions drift beyond your preferred range.
- Notification options: text, email, or push alerts. Apple users can access Critical Alerts; Android users have equivalent options.
- SMS limits: messages are capped per device, with a hub plus sensor bundle providing a monthly allowance (e.g., 15 free SMS with a hub and one sensor).
- Integrations: supports IFTTT applets and Alexa voice queries to retrieve temperature data and trigger routines.
Usage and setup
Hub required for full functionality, including the mobile app experience. YoLink devices communicate via LoRa rather than WiFi, helping minimize WiFi congestion while still delivering timely updates to your devices and apps.
Ideal for refrigerators, freezers, greenhouses, barns, pet cages, nurseries, and other spaces where stable temperature awareness matters. The 3-pack design gives you a practical starter kit to monitor multiple zones at once.
FAQ
Q: Does this require a hub or WiFi?
A: A hub is required for full app functionality; YoLink uses LoRa, not your WiFi, to monitor conditions.
Q: What alerts are available and how many SMS messages are included?
A: Alerts can be text, email, or push. SMS limits are per device; a hub offers additional monthly SMS capacity.
