هو بروتوكول اتصال لاسلكي يُستخدم بشكل أساسي في شبكات المنازل الذكية، يسمح للأجهزة الذكية بالاتصال وتبادل البيانات وأوامر التحكم مع بعضها بعضاً.
يساعد بروتوكول زد-وايف في التخفيف من مشكلات الطاقة ويوفر اتصالاً لاسلكياً منخفض التكلفة لأتمتة المنزل، ما يوفر بديلاً منخفض الطاقة لشبكة Wi-Fi وبديلاً بعيد المدى للبلوتوث.
يعمل بروتوكول زد-وايف على نطاق التردد المنخفض 908.42 ميجاهرتز في الولايات المتحدة والنطاق 868.42 ميجاهرتز في أوروبا. على الرغم من إمكانية التداخل مع الأجهزة الإلكترونية والهواتف اللاسلكية المنزلية الأخرى التي تعمل بتكنولوجيا Wi-Fi والبلوتوث، فإن بروتوكول زد-وايف يتجنب التداخل مع النطاق 2.4 جيجاهرتز.
تتكون شبكة زد-وايف من أجهزة إنترنت الأشياء ووحدة تحكم أساسية. فعندما تتلقى وحدة التحكم أمراً من تطبيق المنزل الذكي على الهاتف الذكي أو الجهاز اللوحي أو الحاسوب الشخصي للمستخدم، فإنه يوجّه الأمر إلى جهاز إنترنت الأشياء المراد التحكم به. كما يمكن استخدام مكرر زد-وايف أيضاً لتقوية الإشارة ومساعدتها في الوصول إلى وجهتها الأبعد بشكل أسرع.
