sleeps

• modem sleep - 15 mA, WiFi - off, System clock, RTC, CPU - on
• light sleep - 0.4 mA, Wifi, System clock - off, RTC - on, CPU - pending
• deep sleep - 20 uA, WiFi, System clock, CPU - off, RTC - on

modem sleep

by default

WiFi.forceSleepBegin();
WiFi.forceSleepWake();

light sleep

add this at the top

extern "C" {
  #include "user_interface.h"
}

and

 
WiFi.mode(WIFI_STA);
wifi_set_sleep_type(LIGHT_SLEEP_T);

delay(1000); - esp8266 is sleeping

deep sleep

connect D0 to RST

add ESP.deepSleep(36e7); when you want to sleep esp will reset after 36e7 uSeconds (36*10^7 seconds)

restart

ESP.restart()
