Home Assistant is an open-source home automation platform that puts local control and privacy first. It can be installed on various devices, from a Raspberry Pi to a dedicated server, allowing you to control all your smart home devices from a single, privacy-focused system without relying on cloud services.

Why Choose Home Assistant

Home Assistant stands out for its commitment to privacy and local control. Unlike cloud-dependent solutions like Amazon Alexa or Google Home, Home Assistant processes all data locally on your own hardware, ensuring that your smart home data never leaves your network unless you explicitly configure external services.
