YoLink LoRa Smart Outdoor Contact Sensor & Hub Starter Kit — Hub + (2) Gate & Shed Door Sensors, Contact-Closure, Email/SMS/Push Alerts, 1/4 Mile Open-Air Range, Alexa/IFTTT/Home Assistant

Complete starter package to secure remote doors, gates and outbuildings: one YoLink Hub plus two YoLink Outdoor Contact Sensors (ideal for gates, shed doors, lids or windows). The kit supports 300+ devices across the YoLink product family and you can add extra hubs to cover larger homes, condos or multi-building properties. Two AA batteries are included and provide 5+ years of standby life. Long-range LoRa wireless reaches up to 1/4 mile open-air, letting you monitor vehicle gates, pool gates, barns, remote buildings and more where wiring would be impractical or expensive. Avoid monthly monitoring fees — receive instant notifications by email, SMS and push when an alarm or unusual event occurs. Flexible integration: cut off the reed switch to access the contact-closure wires and tie them into relays, alarm panel outputs, switches, buttons or specialized sensors to make legacy equipment smart. Devices are self-powered and wireless, so installation requires no trenching, conduit or electrician. Device-to-device pairing lets two or more YoLink units (for example, a Contact Sensor and a Siren) operate together locally without WiFi, internet or AC power (works with battery-powered or backed-up devices). Works with Alexa, IFTTT and Home Assistant. Requirements: Android or Apple smartphone, plus a wired ethernet port or a stable WiFi connection (2.4 GHz band only).
