Home Assistant is an open source home automation platform that runs on hardware you own, such as a Raspberry Pi or a local server. The Open Home Foundation, a non-profit organisation, runs the project. After installation it scans the network for known devices and offers integrations for more than a thousand brands and services. Devices can then be tied together with an automation engine, for example switching lights on at sunset, and shown on dashboards built by drag-and-drop. Assist, the built-in voice assistant, accepts natural-language commands, supports wake words and can be customised to experiment with AI conversations. Data is processed and stored locally, with cloud access used only as a fallback when a device offers nothing else. Companion apps exist for iOS and Android, and the project sells its own hardware, including the Home Assistant Green hub, Zigbee, Thread and Z-Wave adapters, and a voice device. ## Key features - **Device Integrations**: Detects known devices on the home network and connects products and services from over a thousand brands. - **Automation Engine**: Runs rules across connected devices, such as turning on a light when you arrive or alerting you to an open garage door. - **Custom Dashboards**: Shows the state of the home on pages assembled by drag-and-drop from different card types, usable on phone or desktop. - **Assist Voice Assistant**: Controls the home through spoken or typed natural language on phones, tablets, smartwatches and dedicated voice hardware. - **Energy Management**: Tracks electricity use and solar production so that consumption can be planned. - **Add-on Apps**: Installs extra software next to the core system, for example a DNS ad blocker or the Node-RED automation tool. ## Use cases - **Combining Devices From Different Brands**: Operate lights, sensors and appliances from many manufacturers in one interface. - **Presence-Based Automation**: Use the phone app's location to trigger actions when someone leaves or comes home. - **Private Voice Control**: Give spoken commands through Assist instead of a cloud voice service. - **Monitoring Energy Use**: Follow household consumption and solar output over time. - **Wall or TV Displays**: Send a dashboard to a television with Home Assistant Cast. ## Things to know - **Runs on your own hardware**: The platform is meant to be installed on a device such as a Raspberry Pi, a local server or the project's own hub. - **Non-profit ownership**: The site states that the project belongs to a non-profit foundation and cannot be sold or acquired. - **Cloud is a fallback only**: Cloud data is fetched only for devices that offer no local connection; nothing is stored in the cloud by the platform. ## FAQs ### What is Home Assistant?
