GPIO not always to 0

[marktn]

Hi,

I have a keypad that has a relay NO. I have connected that to my ESP.
It always goes to state 1 but not always to 0
Is there a way when my gpio is 1, it always gets back to 0 after a few seconds.

Code: Select all

Can you draw how things are connected?
I don't think I really understand what you do here.

I have a keypad, that gives a few seconds a signal to my esp.
The signal is given when the code or key is okay. It comes from a NO connection.

GPIO-4 to NO, Ground to COM. It is just a relay the keypad.

Have you installed a pull-up resistor (~10k) between 3v3 and GPIO-4? This setup will most likely need one, as you (also) haven't enabled the internal pull-up (that's with 50 to 80k a tad high). A lower value stabilizes the signal better.
Also, setting a De-bounce time of around 100-300 msec will greatly stabilize the working of your rules.

Please also share your rules, related to this switch.

Thanks! That solved the problem.Keep u the good work!
I have no rules, the status will be send to domoticz to switch on/off my Alarm status.
At this time there is no resistor, but i will do that to be sure.
