Wide-range temperature monitoring

The YoLink Smart Wireless Thermometer tracks temperature in freezers, fridges, greenhouses and pet cages. It sends consistent updates to the YoLink app so you can manage conditions from anywhere. A hub is required to connect the sensor to your account.

LoRa protocol limits

The sensor uses a proprietary LoRa-based protocol instead of Wi-Fi, so it does not crowd your home network. In open air it reaches up to one quarter of a mile, but walls, metal enclosures and distance will reduce that range. SMS alerts are capped at 15 free messages per month per hub and sensor pair.

Replaces manual spot checks

This device removes the need to open doors or walk to remote locations just to read a thermometer. The jump is worth it when you need automatic logs and threshold alerts for food safety, plant health or animal welfare. It does not suit buyers who want a standalone display or local audible alarm without a phone.

Questions about this item

Which YoLink Smart Wireless Thermometer model should I choose for my freezer versus my greenhouse?

The single white model covers both uses; its wide temperature range works in freezers, fridges, greenhouses and pet cages alike.

How does the quarter-mile open-air range perform inside a typical home with walls and appliances?

LoRa reaches through floors and metal enclosures where Wi-Fi fails, so sensors in basements, fridges or detached garages stay connected to the hub.

What does the 15 free SMS per month limit mean for daily high-low alerts?

Each hub plus one sensor gives 15 monthly texts; push notifications and emails are unlimited, so most users route routine alerts there and save SMS for critical warnings.
