Domoticz is a free, open-source home automation system designed to let you monitor and control various smart devices. Developed since 2012, it focuses on being a lightweight, stable, and completely local platform. Core Philosophy and Performance
Lightweight Design: Written in C++, it is incredibly efficient, requiring less than 50 MB of RAM. It easily runs on modest hardware like a Raspberry Pi Zero up to full servers.
Local Control: All automations and logs run directly on your hardware without any reliance on a third-party cloud. This ensures privacy and keeps your smart home working even if the internet goes down.
No Hidden Fees: The software is completely free, with no subscriptions, cloud accounts, or telemetry trackers. Device and Integration Support
Domoticz supports over 150 hardware types and communication protocols out of the box. It unifies different smart home technologies into a single dashboard, including:
Protocols: Zigbee, Z-Wave, MQTT, 1-Wire, EnOcean, and RFXCOM.
Monitored Hardware: Smart meters (P1, pulse counters), solar inverters, EV chargers, and weather stations.
Sensors: Temperature, wind, ultraviolet (UV) radiation, gas, water, and electrical consumption.
Vendor Ecosystems: Seamlessly links components across different brands, such as triggering Philips Hue lights with a different vendor’s motion sensor. User Interface and Ecosystem
The user interface is powered by a scalable, responsive HTML5 web frontend compatible with all modern desktop and mobile browsers.
Dynamic Dashboards: A modular, drag-and-drop canvas layout supporting over 35 customized widgets like dials and energy calendars.
AI & Tech Support: Domoticz natively features Model Context Protocol support. This allows external AI agents to search and control devices seamlessly through its API.
Mobile Applications: Native iOS and Android apps support geo-fencing, push alerts, fingerprint locking, and interactive home screen widgets. Automations and Customization
