A free, powerful "brain" for your smart home. Instead of having 10 different apps on your phone, Home Assistant connects devices from all manufacturers into one cohesive system. The system prioritizes local control – allowing you to decouple many devices (e.g., Zigbee) from external servers, ensuring lightning-fast response times and functionality even without the internet. And if you use cloud-based devices, it integrates them and forces them to work seamlessly with the rest.
Integration of cameras, such as Hikvision. The system knows when you leave thanks to phone integration and arms itself automatically. It can run a presence simulation, randomly turning on lights and closing blinds to deter intruders. If it detects an intruder, it plays a voice warning via Google speakers or TTS. When you return, the house disarms itself.
Automated outdoor lighting and irrigation systems that only trigger when the weather forecast doesn't predict rain.
Precise temperature control and the ability to integrate with local Artificial Intelligence, so you can speak to your home in natural language.
You are limited only by your imagination. Manufacturer apps rarely allow conditions like: "Turn on the light at sunset, but only if someone is home and the TV is off." For HA, it's a breeze.
If the manufacturer of your bulb or vacuum suddenly goes bankrupt and shuts down its servers, equipment in a traditional system stops working. With a properly configured Home Assistant, you maintain control.
Thousands of enthusiasts from all over the world create new integrations every day. Before a new standard appears on the market, Home Assistant usually already supports it.
Home Assistant doesn't require expensive servers. Energy-efficient terminals, like Dell Wyse or HP, NAS servers, or even old laptops are great for starting out.
However, the most popular device for enthusiasts is a microcomputer.
