You need to connect it using an RJ11 connector. This is the pinout to use
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?
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!
