Archived project

The GitHub repository for this project is archived: it is read-only and no longer updated. What follows describes the project as it was, so check for a newer alternative before you build it.

A NeoPixel light with 144 pixels that you control from the Home app, with colour and brightness. The ESP8266-12E drives the strip and answers the web requests of the Homebridge NeoPixel plugin.

Homebridge is a program that runs on a computer such as a Raspberry Pi, and makes devices that do not support HomeKit show up in the Apple Home app. This project dates from the Homebridge years, before the native HomeKit firmware of this site. For how the site builds HomeKit devices today, see HomeKit or Matter for your ESP32.

How it works

The ESP8266 runs a small web server. It looks at the request of the plugin and reacts to the words on, off, set, status, colour and brightness: it switches the strip, sets a colour or a brightness, or answers with the state. The plugin that sends these requests is in Homebridge Plugin for a NeoPixel Strip.
