ESP-01S with Relay Board and Push Button Toggle

[ldellus]

Hello,

I have an ESP-01S connected to a relay board, which works fine from HomeKit, but I'd like to add a push button to toggle the relay manually. My MEPLHAA script is:
{
"c":{
"io": [[[0], 2], [[2], 6]] #GPIO 0 is the relay, GPIO 2 is the push button. I soldered it between the ESP-01S GPIO 2 and ground
},
"a":[{
"0": {"r":[[0]]},
"1": {"r":[[0, 1]]},
"b": [[2], [2, 0]] # This is part I can't figure out. After power on, pressing the push button turns on the relay only once, then nothing.
}]
}
Appreciate any guidance you can give.
Thanks,
Laurent

If it's a pushbutton, change "b": [[2], [2, 0]] to "b": [[2]]. Then if its just soldered between GPIO2 and GND without any pull-up, you should declare "io": [[[0], 2], [[2], 6, 1 , 1]] to turn on the internal pull-up and invert the button behavior (active when low)

It works! thank you so much for the help. I thought about the pull-up but didn't realize I needed to declare the io.
Sharing the full script for the benefit of the community. A push button is soldered between GPIO 2 and GND.

},
"a": [{
"0": { "r": [ [ 0, 0 ] ] },
"1": { "r": [ [ 0, 1 ] ] },
"b": [ [ 2 ] ]
}]
