Hi,

I just found this arduino/esp-sketch and it is kind of what I'm looking for. Thanks! But I could not find out how to connect the esp8266 to my smart meter. Can you give me some information or picture about that?

Thanks in advance!

You need to connect it using an RJ11 connector. This is the pinout to use RJ11 P1 connetor

Connect GND->GND on ESP, RTS->3.3V on ESP and RxD->any digital pin on ESP. In my sketch I use D5

@jantenhove question about this, what if you have an rj11 connector with 4 kables instead of 6, will it work? And what is the pinout then?
