normal switch without real function?

[thobastian]

Hi,
I am new here in forum, but have general know how in arduino and esp easy.

I start a test project with nodemcu, espeasy v2.0 and a normal cable between gnd or V3.3 and D6.
I'll test the witch function of esp easy. It work like here:
If I connect the D6 on GND, I get a "0"
If I connect the D6 on V3.3, I get a "1"
If I disconnect the D6 , I get the last status from last test. But this is bad.
This isn't usable for a normal switch (like a wall mounted switch in a house)

How you solve this problem?

Typing this on my phone, but, have you looked into switch settings? Internal pull up etc?

You need to add a pull-up or pull-down resistor, which ties the otherwise floating state of an unconnected pin to either HIGH or LOW. Of course, you can't distinguish between unconnected and switch open then.

In my settings, I switched to pull-up , but nothing happens.

If you've created a Switch device in ESPEasy, to D6-GPIO12 with "Internal Pullup" then after submitting it, you can measure 3.3V at the D6 pin on its own (without cable connected), and value of 1. If not, than try D5 or D7. If you connect it to GND with a cable, than it will go to 0. Except if you configured this pin to OUTPUT at the Hardware settings, which would surprise me, or if it is a faulty module.

okay, this works good with 3-pin mounted switch, but what about 2-pin ?

I do not really understand what you mean about 3-pin.
I am using 2-pins. 1st is the GPIO and the 2nd pin is GND.
