YoLink Sensor 3-Pack vs Kit
Included components
The YoLink Door and Window Sensor 3-Pack provides three individual sensors without a hub. You must purchase a compatible hub separately to access full smart features. In contrast, the YoLink Door and Window Sensor Kit with Hub comes with two sensors and the necessary YoLink Hub pre-included. This kit offers a complete starting setup, while the 3-Pack requires you to source the central communication device independently. The kit simplifies initial deployment by bundling the essential gateway hardware.
Sensor quantity
You receive three sensors in the 3-Pack, covering more entry points per box. The Kit includes only two sensors, limiting your immediate perimeter protection. If you need to secure three doors or windows right away, the 3-Pack saves you from buying an additional single sensor. However, the Kit provides the hub needed to connect those sensors to your network. Consider your total coverage needs against the included hardware count when choosing between these two options.
Connectivity technology
Both products utilize LoRa wireless technology operating on the 900 MHz band. This allows for long-range communication up to 2,034 feet in open air, outperforming standard Wi-Fi in range. You can place sensors in basements, sheds, or on RVs where Wi-Fi signals are weak. Neither product relies on Wi-Fi for sensor communication. Both offer identical signal strength capabilities and device-to-device pairing features for local actions, even during internet outages.
Power source
Both the 3-Pack and the Kit sensors are battery-powered. The Kit explicitly states that batteries are included and preinstalled, lasting up to five years between changes. The 3-Pack data does not specify battery inclusion, though sensors of this type typically require batteries. You will need to verify if the 3-Pack includes pre-installed batteries or if you must supply them separately. Both rely on the same efficient battery technology for long-term operation.
Installation method
Installation is identical for both products. You scan the QR code on each sensor, assign a name, and peel the protective plastic from the pre-applied 3M mounting tape. Press the sensor and magnet to the door or frame for immediate setup. Both use the same adhesive backing and magnetic alignment. The process takes moments for each unit. No tools are required for either the 3-Pack or the Kit, ensuring a quick and straightforward deployment for all included sensors.
Choose the right YoLink sensor setup
Users who already own a YoLink hub
You already have a compatible hub. This 3-pack gives you three sensors without buying redundant hardware. The model YS7704-UC*3 includes only the sensors. You save money by skipping the hub. The sensors use LoRa connectivity. They pair directly to your existing system. This option is ideal for expanding coverage.
New users needing a complete starter system
You need everything to start immediately. This kit includes two sensors and a regular hub. The model YS1603-UC+YS7704-UC*2 provides a complete setup. Batteries are preinstalled for up to 5 years. You avoid purchasing a hub separately. The 900 MHz LoRa range supports up to 300 devices. This is the easiest path for beginners.
Buyers wanting more sensors per package
You need coverage for more entry points. This pack contains three sensors. The other kit only includes two. You get an extra sensor for the same or lower cost if you already own a hub. The sensors share identical hardware. You can monitor more doors or windows. This option offers better sensor density for your perimeter.
