# WifInfo
## Overview
A few months ago, I came across a project called Wifinfo. It's a small board, based on an ESP8266, which retrieves information from the French power meters and displays them, or sends them across the network. The PCB was cheap, and I though I could use one, so I built some boards ! Turns out, I can't, since the telemetry option is disabled in my power meter…
## Hardware
I uploaded the files on OSHPark and also shared them, so anyone can easily order them: [OSH Park](https://oshpark.com/shared_projects/Rjzd7tY7)
## Software
### Tools
The firmware is an Arduino sketch, so you will need:
- The Arduino IDE - The ESP8266 _extension_ for the Arduino IDE - The “ESP8266 Sketch data upload” tool for the Arduino IDE - Some libraries such as:
- NeoPixelBus, for ESP8266
### Firmware
Grab the firmware from the LibTeleinfo Github project
### Upload
You need to put a jumper on the board between the TX and TX1 pins, on the three pin header on the right.
Connect your serial Adapter to the board (on the six pins header on the right): RX on TX, TX on RX, GND on GND. I used an external power supply but you can also probably use the 5v pin to power the board.
