ESP8266 Community Forum

German DIY market OBI is selling a WiFi socket (look for item "OBI 2291706"). It contains an ESP chip, two LEDs, a push button, power supply and a relay in a socket case.

I am just trying to explore it and to flash it with custom firmware: https://github.com/martin-ger/ESP8266-WiFi-Socket

Added a simple Arduino sketch that controls the device: https://github.com/martin-ger/ESP8266-W ... Socket.ino
