Do you have any sensor connected to this (relative high) voltage?
And what signal level is sent to the ESP device input pins?

A reed switch short circuits the contacts. So you also need some resistor in series with the reed switch.For the reed switch of the counter i pick a 3.3V and Gnd from two pins of NodeMcu board.
If the AMS1117 is still in the loop, you have to make sure you feed it with a high enough voltage.
