What is Home Assistant?

Home Assistant is an open-source operating system that prioritizes local device control and privacy. The system has the support of a huge community. It can work on the basis of a Raspberry Pi minicomputer or Home Assistant Yellow with a Raspberry Pi Compute Module 4, Seeed reTerminal and a mini router with dual Gigabit Ethernet or a local server, such as Seeed Odyssey Blue with an Intel Celeron J4125 processor. The Home Assistant system has a web user interface that can be connected via a web browser or a dedicated application for Android and iOS. The system also supports voice assistants such as Google Home and Amazon Alexa. The voice assistant enables local control of smart home devices, offering better security, greater reliability and greater flexibility than many cloud-connected devices.
