YoLink Smart Temperature & Humidity Sensor 3-Pack — Long-Range LoRa, App + SMS Alerts

YoLink Smart Wireless Temperature & Humidity Sensor (3-pack) is a long-range LoRa sensor set that monitors temperature and humidity remotely, sending app, email, and text alerts (hub required).

These compact sensors pair with a YoLink hub to provide continuous temperature and humidity readings across an extended range without using your home WiFi. Designed for indoor and semi-protected uses like refrigerators, grow rooms, pet enclosures, and storage areas, the 3-pack includes batteries so you can install and start monitoring right away. The LoRa-based radio conserves battery life while reaching places ordinary WiFi devices cannot, and the YoLink app delivers configurable alerts and history.

How does the YoLink sensor keep me informed about temperature changes?

Each sensor measures temperature and humidity on a regular schedule and sends the data to your YoLink hub, which then forwards alerts and logs to the app and configured contacts. You can set high/low thresholds and choose notification channels like push, email, or SMS. This multi-channel approach helps ensure you get notified even if one channel is missed.

• Push notifications and in-app history for quick access
• Email alerts for record-keeping and sharing
• SMS alerts (monthly limits apply) and critical-phone alerts for urgent conditions
• User-set high/low temperature and humidity triggers

What environments are these sensors suitable for?

These sensors work best in indoor, refrigerated, or semi-protected locations where humidity and temperature need monitoring but full weatherproofing is not required. They are commonly used inside fridges, greenhouses, pet cages, storage rooms, and multi-floor homes because LoRa range reaches farther than WiFi. For fully outdoor, exposed sites consider YoLink’s weatherproof sensor variants.

• Food and beverage fridges — monitor cold chain temperature
• Greenhouses and plant nurseries — track humidity and temp swings
• Pet enclosures and nurseries — ensure stable conditions
• Basements, attics, and garages several floors from the hub

How does LoRa-based connectivity benefit battery life and range?

YoLink sensors use a LoRa-derived wireless protocol rather than WiFi, which dramatically reduces power consumption and avoids congesting your home network. That lower-power radio lets AAA batteries last for years under typical reporting intervals while allowing signals to travel much farther and penetrate obstacles better than standard smart-home WiFi devices.

• Low-power operation extends battery life beyond two years (batteries included)
• Greater transmission range reaches around corners and floors
• Does not use or burden your home WiFi network
• Ideal for distant or signal-challenged locations inside buildings

What integrations and automation can I use with YoLink sensors?

The YoLink system supports integrations like IFTTT and limited Alexa voice queries, enabling automations when thresholds are crossed. While Alexa can verbally report temperature, it does not support humidity queries or Alexa-initiated routines with these sensors. Use IFTTT applets to trigger other smart devices or workflows when a sensor reports an out-of-range condition.

• IFTTT triggers for cross-platform automation
• Alexa temperature voice queries only (no humidity or routine triggers)
• App-driven alerts, email, and SMS notification options
• Hub compatibility expands to other YoLink products

Who is this for? The YoLink 3-pack is aimed at homeowners, small business operators, hobby growers, pet owners, and anyone who needs reliable remote temperature and humidity monitoring in locations beyond ordinary WiFi reach. If you want long-range, low-maintenance monitoring for fridges, grow areas, cages, or distant rooms—and prefer multiple alert options and easy automation—this YoLink sensor pack is a practical choice. Remember: a YoLink hub is required for full functionality and is compatible with a growing family of YoLink smart devices.
