Self-Hosted

Open-source home automation system for IoT device control

Overview

FHEM is an open-source home automation platform designed to integrate and manage IoT devices. It supports thousands of devices (sensors, thermostats, smart plugs) via modular plugins, enabling custom automation workflows like schedules and conditional triggers. FHEM runs locally (Linux, Raspberry Pi, Docker) for privacy-focused control, with a web UI and mobile access. Its Perl-based backend allows advanced scripting, making it flexible for tech-savvy users. Deployment is straightforward via packages or Docker, ideal for self-hosted IoT setups.
