Smart Relay

Many homes still use traditional mechanical light switches — but that doesn’t mean you can’t turn them into part of a modern smart home. In this video I show you how to convert almost any existing light switch into a smart switch using an affordable smart relay module — without replacing your switches and even in setups without a neutral wire, which is very common in Europe. We’ll go step-by-step through the installation process: how the wiring works, how the smart relay connects to your existing switch, and how to safely install it behind the wall switch. I’ll also explain why smart relays are often a better solution than smart bulbs, how Zigbee smart switches work, and how you can integrate them with Home Assistant and Zigbee2MQTT for a fully local smart-home setup without relying on cloud services. If you’re looking to upgrade your home lighting, build a smarter home on a budget, or start your Home Assistant journey, this guide will show you the easiest way to do it. 📸 Chapters 00:00 – Intro 00:40 – What will we install? 01:26 – No-neutral wiring explained 02:30 – Zigbee smart relays overview 03:20 – Tools you’ll need 04:22 – Installing the smart module 07:10 – Pairing with Zigbee2MQTT 08:15 – Home Assistant setup 09:32 – Drawbacks & final thoughts 🎥 Subscribe for more honest tech reviews and smart-home guides! 🔔 Turn on notifications so you don’t miss the next inspection. 🏠 Smart-home gear mentioned in the video 📦 Smart relay module https://geni.us/Smart-relay 🏠 Home Assistant Green https://geni.us/HA-GREEN 🏠 More smart-home tech https://www.youtube.com/watch?v=HcKvg0GebL0&list=PLczsTBo27jX69EOTcResYoBsUhKFcQ7DP 🛠️ Recommended gear 📸 Great CAMERA for YouTube: https://geni.us/mycAm 📸 A bigger CAMERA: https://geni.us/nHrgUik 📱 My favorite SMARTPHONE: https://geni.us/8zgx 🚁 DJI’s awesome DRONE: https://geni.us/44pgOd ⌚ My favorite SMARTWATCH: https://geni.us/5l7I 📷 A cool ACTION CAMERA: https://geni.us/EAjPFi 📷 The best 360° CAMERA: https://geni.us/One-X2 🚴 My SCOOTER: https://geni.us/5AC67Y 🎥 The GIMBAL: https://geni.us/DRjj 🎵 Music used in this video https://geni.us/Epidemic_Sound ٩(-̮̮̃•̃)۶ 💬 Enjoyed the video?
