Binary input does not respond after triggering

Hello everyone I am building a multiple function switch with ESP-12F and this firmware.
I connected a relay to GPIO 12 and a button between GPIO 13 and VCC.
I constructed MELPHAA script like this:

{
  "c": {
    "io": [
      [[12], 2],
      [[13], 6]
    ],
    "l": 2,
    "b": [[0, 5]]
  },
  "a": [
    {
      "0": { "r": [[12, 0]] },
      "1": { "r": [[12, 1]] },
      "b": [[13]],
      "t": 1,
      "s": 5
    }
  ]
}

Then I deployed the software and hardware. A problem occured: when I tried to switch the status of the relay by the button, it would work once and stop working for a while, then it can work again but lost respond after triggering. It seems that it has a "cooldown time".
Did anyone encounter this problem? I really need your help!

According to your description and the script, there seems to be nothing wrong in this behavior. If the button is between GPIO13 and VCC, you would need to have a pull-down resistor to allow the voltage to drop and the input to reset.

However ESP8266 (the micro inside ESP-12F) doesn't feature internal pull-down resistors, so you have 2 options:

1. install a pull-down resistor (4.7kOhm would work) between GPIO13 and GND and change its initialization to [[13],6,0,1] so to enable the invert GPIO behavior (active high)
2. connect the button between GPIO13 and GND and change its initialization to [[13],6,1] so to enable the internal pull-up

The fisrt option works for me. Thanks a lot.

Though I realized it seveal days after I posted the discussion, I still appreciate your help. It is needful to check the document of the chip. 😀
