Home Assistant

Description

Home Assistant is an open-source home-automation platform that puts local control and privacy first. It is a self-hostable alternative to SmartThings, Google Home, and Alexa routines: automations run on your own hardware, device state stays on your network, and there is no dependency on a manufacturer's cloud. With more than 3,000 integrations, a customizable dashboard, a local voice assistant, and energy monitoring, it can act as the single hub for an entire home.
