A local-first garage opener: open-source ESP8266 firmware, a built-in web UI and HTTP API, and an ultrasonic sensor that reports real open/closed state. Home Assistant ships an official OpenGarage integration that polls it locally, so nothing leaves your network. Newer hardware revisions add native Security+ 2.0 support for recent Chamberlain/LiftMaster openers.
Standout: An open-source WiFi garage controller with a built-in ultrasonic door-position sensor and a fully local HTTP API - no cloud account required.
