Power Saving tips for the ESP8266

Software Tips

Use DeepSleep.

This is the #1 recommendation when designing a low power ESP8266 application. Note that this requires hardware changes, too. GPIO16 must be tied to the RST pin, and RST should be pulled HIGH externally. The ESP8266 will pull GPIO16 LOW to reset the chip once the deep sleep timer expires.
