ok, if digital output signal, you can use any S1,S2,S3,S4 port. just S3 and S4 can use for long distance wire, support 300 meter wire. S1 and S2 is short distance.

connect to S1 or S2, not use S3 and S4. S3 and S4 need voltage >6v is better.

i think you can try to test, connect S1 or S2 to "GND" or to "3.3v", whether work well in esphome.
