I’ve been diving into the world of IoT and building a home automation system for my two-story home. Each floor has multiple rooms, and each room houses several Raspberry Pi devices controlling various smart gadgets. The challenge has been managing all these devices from a single control center. After some research, I stumbled upon MQTT as a potential solution for seamless communication between devices. I’ve been exploring how to set up MQTT with OpenHAB2, aiming to create a structured system that mirrors the hierarchy of my home. My goal is to install OpenHAB2 on a Windows machine and connect all my Raspberry Pis to it, enabling me to control every pin and monitor the status of all devices in real-time. If anyone has experience or resources on implementing MQTT in OpenHAB2, especially for such a setup, I’d greatly appreciate your insights or guidance!
