McLighting v2 - The ESP8266 based multi-client lighting gadget
Mc Lighting (the multi-client lighting gadget) is a very cheap internet-controllable lighting solution based on the famous ESP8266 microcontroller and WS2811/2812 led strips. It features a self-hosted responsive web-interface, a REST-API and a websocket connector.
Because of it's open architecture and APIs it's easy to build new clients for different platforms (iOS, Android, Windows Universal Apps, Siri/Cortana integration, ...).
Update 16.12.2017: There was a breaking change in the WS2812FX library: Speeds have a new format (65535-0 instead of 0-255). I released a new version that converts the speeds settings. Please use the latest WS2812FX library (14.12.2017 or later) if use have an existing version installed. I got many messages from people who use McLighting for own projects. User Brian Lough built a lighting system for his wedding and made a nice instruction video for his build: https://goo.gl/NbfKi8
Update 30.09.2017: Thanks to @moose4lord Mclighting works with the newest version of WS1812FX and has a possibility to define autocycle patterns Wiki. Thank for contributing to McLighting everyone! I was also informed of a new project that is loosely based on McLighting: Responsive_LED_Control That looks very promising.
Update 07.08.2017: As requested by many of you, McLighting now also features MQTT support. Thanks at @LeonVos for his attempts on this. I implemented the same API as used in WebSockets now for MQTT. Please have a look here for details: https://github.com/toblum/McLighting/wiki/MQTT-API I will try to add a new instruction video soon.
Many of you also took McLighting and adapted the software according your needs. This is great. I found some videos on YouTube that show these projects. I collected them here: https://goo.gl/yG7M4h If you have done something similar with McLighting, please drop me a note. I'm always interested in what you've done with it.
Update 19.02.2017: Added OTA support as promised by @markbajaj. Minor other improvements.
Update 05.02.2017: After a long time I was able to work a bit on McLighting v2 and it's finally out now. The main difference, among minor improvements and library updates, is the usage of the great WS2812FX library for color animations. It brings a lot (almost 50!) of new animations. The API changed a little bit, because the speed can now be set as a value from 0 to 255, not the delay anymore. So the web inferface had to change accordingly. The new animation mode have to be set also by their number, instead of a dedicated url. The list of all animation modes can also be received by the API. All existing API endpoints are kept for downward compatibility. So you should be able to use the new version without big changes. The original version is kept as branch "mclighting_legacy". Documentation will be updated soon.
Now, there are two forks of McLighting (using the famous FastLED library). I did not notice it first, because I currently do not receive notification e-mails by Github (I have no idea why). Maybe you want to give them also a try, I will definitely do so as soon as I find time.
And this one was also forked: https://github.com/jake-b/Griswold-LED-Controller
Update 12.08.2016: There is now a gitter.im chat room for this project.
Today I presented the project at Pi and More 9 and got some good feedback, even though my presentation was not perfect and time was too short to present everything I prepared. So I uploaded the slides (german) to this repository for your reference.
The project ist based on the famous ESP8266 microcontroller and WD2811/WS2812 LED strips. There are many variations of the ESP chip out there, but I chose the NodeMCU dev board, because it's powered by micro USB and has a voltage converter included to power the ESP which uses 3.3V. A standalone ESP8266 or a Adafruit Huzzah should work too.
The RGB LED strips are also available in many different flavours as strip or as standalone LEDs and can easily be chained.

You use this project at your own risk. This is not a solution that should be used in productive environments, but this code and guide could give you a quick start for your own experiments. Please keep also in mind that there are currently some security features missing.
More information will be added as soon as I clean up the code and complete documentation.
