What is Home Assistant? A clear introduction

What is Home Assistant? A clear introduction for beginners

Home Assistant is one of the most flexible and powerful smart home systems available today. Unlike many manufacturer-specific solutions such as Alexa, Google Home, or proprietary smart hub concepts, Home Assistant operates entirely locally. This means that control runs directly on your own network—faster, more secure, and without cloud dependency.

Why Home Assistant is so special

The platform was developed to unite devices from a wide range of manufacturers in one system. Whether Philips Hue, IKEA Tradfri, Shelly, Bosch, Sonos, Govee, Zigbee devices, Wi-Fi sockets, or even vehicle integrations from BMW or Tesla—Home Assistant can combine all these systems. This allows for automations that would be virtually impossible with individual manufacturer solutions.

Another advantage: Home Assistant is open-source and easy to expand. With add-ons such as Node-RED, MQTT, ESPHome, Grafana, or InfluxDB, even complex automations, visualizations, or device connections can be implemented.

Where does Home Assistant run?

Home Assistant is flexible and can be run on a wide range of hardware:

  • Raspberry Pi
  • Intel NUC
  • Synology oder QNAP NAS
  • Proxmox
  • Docker
  • Industrial PCs or home servers

This makes the system suitable for both small apartments and large residential or commercial installations.
