This last one (whatever the relay PCB) refuses to activate the relay, here-below what I captured on the serial line when the magic packets (close and then open) is sent via wifi:

+IPD,0,4:�␁␁�
+IPD,0,4:�␁␀�0,CLOSED
I forgot to say that I am a newbe with esp8266, but I sure you saw it at the fisrt line...
any help will save several nights of good sleep for me
