WEMOS D1 wake up by button

Question

I am asking for help, how can I WEMOS D1 wake up with the button? I know how to do this after some time using:

ESP.deepSleep (180000000)

Please help.

use reset button. in deep sleep the esp8266 is complete off. only RTC is running and sets io 16 LOW if there is time for wake-up. io 16 must be wired to reset for wakeup from deep sleep — Juraj, Feb 07 '20 at 21:23
there is nothing more. but it should by " io 16 must be wired to reset for wakeup from deep sleep by timer" — Juraj, Feb 08 '20 at 09:13
What is `ESP.deepSleep`? Possibly you mean node.dsleep() https://nodemcu.readthedocs.io/en/master/modules/node/#nodedsleep — sergio, Feb 09 '20 at 21:22

Will this action not damage WEMOS D1? – Bartek Feb 14 '20 at 12:25
No. Being pulled to GND (for a short time) for hardware reset is what the RST Pin is supposed to be used for. – PrfctByDsgn Feb 17 '20 at 06:51

This function can only be used in the condition that esp8266 PIN32(RST) and PIN8(XPD_DCDC aka GPIO16) are connected together. Using sleep(0) will set no wake up timer, connect a GPIO to pin RST, the chip will wake up by a falling-edge on pin RST.
