This repository is a collection of custom integrations for Home Assistant, the open-source home automation platform. It is distributed via HACS, which is an add-on manager for Home Assistant that lets users install community-made integrations that are not part of the official release. The project was built by one person with AI assistance and is described as early-stage software at version 0.4.0. The first integration included is called IR Remote Buttons. It is designed to let you use any ordinary infrared remote control, the kind that comes with a TV or stereo, as a trigger for Home Assistant automations. The idea is that you point the remote at an infrared receiver connected to your Home Assistant setup, teach the system what each button looks like by pressing it twice in a learning flow, and then use those button presses to trigger whatever automations you want. The integration also supports double-click detection, so a single button can trigger two different actions depending on whether you press it once or twice quickly. Installation goes through HACS by adding the repository URL as a custom source, then searching for the integration by name and downloading it. Once installed and restarted, you add it through the Home Assistant settings screen, select your infrared receiver, name your remote, and start teaching it buttons one at a time. Each button you add becomes available as a trigger inside automations. The README includes a section on hardware configuration for users running an ESP32 or ESP8266 microcontroller as the infrared receiver. It goes into detail about three timing settings that control how the receiver captures button signals, and explains how getting these wrong causes buttons to fail to learn or fire inconsistently. The guidance is technical but practical, covering idle timeout, signal buffer size, and timing tolerance, with recommended starting values for each. The project also includes ready-to-flash firmware configuration files for both ESP32 and ESP8266 boards, along with a template for storing credentials separately from the configuration.
