Three-Sensor Kit with Hub

This pack includes three wireless thermometer-hygrometer sensors and a dedicated hub, designed for users who need simultaneous temperature and humidity monitoring across multiple locations such as freezers, greenhouses, pet enclosures or wine storage. The system suits homeowners, gardeners and small-scale livestock keepers who want remote visibility without adding load to their home Wi-Fi network.

LoRa Hub and Power Requirements

Before ordering, confirm you have a free Ethernet port on your router or switch for the hub, which connects via wired LAN to reach the internet. The hub also needs a nearby mains outlet for its power adapter. Sensors communicate with the hub over a proprietary long-range radio, so no Wi-Fi credentials or Bluetooth pairing are required during setup.

Battery-Powered Placement Freedom

Each sensor runs on an included battery rated for up to five years of operation, eliminating the need for wiring or frequent recharging. The hub handles all cloud connectivity and provides 15 free SMS alerts per month shared across the system, while push notifications and email alerts remain unlimited. Sensors can be placed in metal enclosures, basements or outbuildings where traditional wireless signals struggle to penetrate.

Questions about this item

What comes in the 3-pack and is the hub included?

The package contains three wireless thermometer-hygrometer sensors and one YoLink hub, so no separate hub purchase is required.

How do I decide between using the sensors in a freezer versus a greenhouse?

Each sensor covers the same wide temperature range, so you can place any of the three units in a freezer, fridge, greenhouse or other location without choosing a different model.

What does the 15 free SMS per month mean for daily alerts?

A hub with one sensor provides 15 free SMS messages each month; additional sensors share that pool, so frequent text alerts will use the allowance quickly.
