Home assistant ile zha modeda bagladim. Kapi acildiginda kameram kapiya dönüp kayıt başlatıyor, kapandiginda kameram kaydi bitirip onceki yerine dönüyor. Bu sekilde kullaniyorum :) milisaniyelik algilamayla mukemmel işlevsel. ### ⭐⭐⭐⭐⭐ Preiswerte Smart-Home Austattung | ! Fritz SmartGateway kompatibel ! *by on Reviewed in Germany 2 July 2026* Ich habe mir 2 dieser Sensoren gekauft um diese in mein Smart Home System von FritzBox einzupflegen und für meine Heizkröperthermostate als Fenstersensoren zu kalibrieren.In meinem SetUp habe ich die FritzSmart Thermostate 302 und 301 verbaut.Eine DSL FritzBox und auch ein Fritz Smart Gateway.Da diese Sensoren ZigBee unterstützen was ich über das Fritz Smart Gateway kalibrieren kann was es super einfach alles eingerichtet. Den Sensor aktiviert, das Smart Gateway in den Kopplungsmodus und schon hat die FritzBox das ZigBee Gerät als Fenstersensor erkannt.Anschließend musste ich den Sensor nur noch dem jeweiligem Thermostat zuweisen und schon hat das System funktioniert.---Für diejenigen die ein SmartHome System über die FritzBox laufen lassen wollen und dazu auch ein SmartGateway von Fritz haben, kann ich diese Sonoff Sensoren absolut empfehlen. Funktionieren zuverlässig und sind bei weitem günstiger als die Sensoren von Fritz direkt. ## Frequently Bought Together - SONOFF SNZB-04P Zigbee Door Window Sensor, Send Alert to Your Smartphone for Home Security, Compatible with Alexa/Google Home, SONOFF Zigbee Bridge Required, Batteries Included - SONOFF Universal Zigbee 3.0 USB Dongle Plus Gateway with Antenna for Home Assistant, IoBroker, Zigbee2MQTT --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/643509341-sonoff-snzb-04p-zigbee-wireless-door-window-sensor-send-alert](https://www.desertcart.sk/products/643509341-sonoff-snzb-04p-zigbee-wireless-door-window-sensor-send-alert) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-09-08*
