The YoLink LoRa Smart Door & Window Sensor 3-Pack is designed to provide peace of mind by keeping you informed about the status of your entry points with minimal maintenance and maximum reach. Whether you’re monitoring doors, windows, cabinets, or other access points, this wireless smart sensor delivers open/close alerts, “door left open” reminders, and exceptional battery life — up to 5 years on standard use. I chose this sensor because it combines industry-leading range, compatibility with smart home ecosystems like Alexa, IFTTT, and Home Assistant, and practical notifications that help keep your home—or business—safer and more connected than ever.
Best For
Homeowners, smart home enthusiasts, families, and anyone who wants reliable door/window activity alerts with wide coverage and long-lasting battery performance.
Why These YoLink Smart Sensors Stand Out
Traditional contact sensors often suffer from limited range, frequent battery changes, or unreliable alerts. The YoLink LoRa Smart Door & Window Sensor solves those issues with a long-range LoRa wireless protocol that can cover up to 1/4 mile open-air range, making it ideal for large homes, workshops, outbuildings, or even properties with detached structures.
What also sets these sensors apart is their multi-ecosystem compatibility. Once paired with a YoLink hub (required), these sensors not only send instant open/close notifications but can trigger routines and automations through Alexa, IFTTT, or Home Assistant. That means you can automatically turn lights on when a door opens at sunset, send alerts to your phone if a window is left open too long, or integrate them with other smart devices for complex automation scenes.
I also appreciate the 5-year battery life — a standout feature that virtually eliminates the need for frequent maintenance. In real use, this sensor package is ideal for internal and external entry points you want to monitor reliably without worrying about replacements every few months. Whether you’re checking on children returning from school, ensuring a garage door isn’t left ajar, or automating smart lights, these sensors make home monitoring easy and proactive.

How the YoLink Smart Door & Window Sensor Works
The YoLink Smart Door & Window Sensor uses a LoRa (Long Range) wireless protocol to communicate status back to your YoLink Hub, which then relays notifications to your smartphone and integrates with smart home platforms. Each sensor has two parts: the sensor and the magnet. When the two parts separate (door/window opens), the sensor triggers an alert. When they realign (door/window closes), the alert clears.
From experience, the strength of the LoRa signal means far fewer “dead zones” compared to standard Wi-Fi or Zigbee sensors — especially helpful in basements, garages, and large properties. Alerts and automation rules can be configured in the YoLink app, giving you flexibility for reminders, integrations, and multi-sensor automation.
YoLink Smart Sensors vs Other Contact Sensors
vs Standard Wi-Fi Sensors: YoLink’s LoRa technology delivers significantly greater range and fewer connectivity issues, especially in homes with Wi-Fi dead spots.
vs Zigbee/Z-Wave Sensors: These alternatives often require a smart hub for compatibility, but YoLink’s hub enables long-range coverage without mesh reliance.
vs Bluetooth Sensors: Bluetooth contacts require close proximity; YoLink sensors offer broad coverage for larger properties.
For smart home enthusiasts and those needing reliable, long-range entry monitoring with minimal maintenance, the YoLink Smart Sensor 3-Pack offers superior coverage and durability.
