Sonoff SNZB-04P Zigbee Door and Window Sensor: Zigbee wireless protocol
This SONOFF door and window sensor is for anyone who wants to know the instant a door opens—whether you're home or away. Perfect for monitoring a back door while you're in the basement, or checking that your teenager made curfew.
Instead of just another alarm trigger, think of it as a local watchdog. You pair it with your Zigbee hub, then create automations that run inside your home, not over the cloud. When the door opens, a light can turn on or a siren can sound—all without internet lag. The motion alert hits your phone before your key turns in the lock.
It works with Alexa, so you can say "Alexa, is the garage door open?" and get an answer. No subscription, no monthly fees. Simple, direct, and always watching.
