According to my understanding, there are two ways to wake up from deep sleep:

setting a timer (ESP.deepSleep(time in uS, mode)). GPIO16 must be connected to the external reset pin for that work.
pulling down the external reset pin

Isn't there a way to wake up the chip using the GPIOs, with something like, say, a pin interrupt? Using the external reset pin isn't a great choice, because it will reset the chip even if it isn't sleeping (if, for example, I connect a motion sensor to the reset pin, the chip will be reset every time motion is detected, not only when the chip is in deep sleep).

You would connect the motion sensor to a pin and have code that is run by interupt when triggered I would say . Deep sleep starts the chip from scratch . Interupts dont and there are quite a few ways to sleep during running . See the wiki above

I'm sorry, but I don't understand what you're trying to say.

You're suggesting that I try running code with an interrupt. What exactly do you mean by that? Are you suggesting that I use something other than deep sleep mode?

This guy simply doesn't know any things about what he is talking ...
During deep-sleep, interrupts wont be served at all !!! The only way to go out of deep-sleep is to have a reset.
