Hi all,

I'm wondering that can we put esp8266 nodemcu into deep sleep mode and when it wakes can we provide a condition to go back to sleep? ie. d1 == high go to sleep, wake up with external interrupt if d1 is low don't sleep and do the stuff?

regards,

Yes. Conditional deep sleep is possible. To wake up, you can use a button connected to the RST pin or timer wake up.
