Posted: Thu Apr 23, 2015 3:22 pmTry the modification on the ESP-01 module like i did. It requires some accurate soldering of the SMD capacitor, but it's doable. I have modified two modules and they work great now.

Posted: Thu Apr 23, 2015 4:52 pmI believe you, but since I don't want my modules altered, and since I'm not driving relays, I should be fine with PullUp/Cap for now. (BTW, maybe I'm wrong, the other ESPs seems to be less sensitive then ESP-01)
