So I want to share what I did the last few months, yeah you got it right, months! Planning, modelling, getting parts, modelling, parts, modelling, getting equipment, modelling, parts, .... I wanted to start with home automation but all made by myself. I am using mostly iDevices aka iPhone, iPad and my wife has one too so the goal was to use the "Home" app from Apple to control physical devices. I found https://github.com/nfarina/homebridge a while ago and started to use it to control my remote controlled outlets for my 3d printers in connection with http://nodered.org and https://mosquitto.org. My goal was to control my two lights I have in the living room, one above the couch table and one for the dinner table, the two uprights left and right of my couch and the backlights in my glass cabinet where my TV is in. Also I wanted to keep 100% manual control of all devices, for the normal light switch I wanted to keep the covers I already had. I bought this (http://www.ebay.de/itm/371861363419) uprights from eBay a while ago, they are LED and controlled with a single button. I reverse engineered the control circuit, removed the controlling IC and replaced it with an ESP8266 and a DC/DC converter. Here are some pictures of the uplight control and installed to the uplight: After that I took care of the normal switches. I have "Busch & Jäger" (https://www.busch-jaeger.de) covers for my switches and I wanted to keep them. So I ordered an ESP8266 controlled relay from eBay fitting a normal wall mount in Germany. The project is also on Github: https://github.com/JanGoe/esp8266-wifi-relay But I had troubles mounting it behind the standard switch and also using the standard switches designed for 230V will make trouble when using the switch PINs powere with 3.3V from the ESP. So I decided to design my own mount and switch to use Omron micro switches. I attached the STLs for a double switch, I am still up to design a switch for only one relay, which I will need for the other rooms I am planning to remote control.
