Yo! This project is still a Work In Progress. Instructions, board layouts and BOM might change!
Make a donation to Giacomo TanganelliThis is an ESP8266-12F based power strip. It provides 4 different power sockets, each one independently controllable. Moreover, it monitors the current consumption of each different socket by exploiting a 4051 multiplexer. This is a work in progress and suggestions are more than welcome. I plan to build my board in two weeks, then I'll start the coding part, which is however the easiest thing for me.
The board has not been tested yet.
