Hey guys and girls
I am playing with the RE5V1C 5V Wifi Inching/Selflock Relay Module https://www.itead.cc/sonoff-re5v1c.html). I want to use it to open and close a garage door, so I need two inputs to be able to know if thew door is fully open and fully closed.
I managed to load Tasmota onto it very easily, but I cannot get any info on the pads
ETX, ERX, TX, RX and IO2. How are they connected to the ESP8266? Does anybody have the schematic or more info?
