This is an EMS Bus interface board to be used with a Wemo D1 Mini ESP-8266 flashed with EMS-ESP
I used the designs based on bbqkees work and from EMS-ESP
A couple of notes on the design, I tried to power the 8266 from the EMS Bus but it did not work, so IC1 and D1 are not needed, and make sure that there is no jumper on on J4
