- | 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... | + | A few months ago, I came across a project called Wifinfo.
