{"NAME":"HW-622","GPIO":[0,0,157,0,21,17,0,0,0,0,0,0,0],"FLAG":0,"BASE":18}DYI ESP8266 relay with external optoisolated button. Requires an external power supply. The input from the switch is opto-isolated so the 5V can be used directly to supply the switch. Unfortunately, it appears that many cevices do not have the 0V connected on the input. A connection needs to be made from the 0V on the supply to the 0V on the signal input.
