DeepSleep","

Switch the node to deep sleep.
Max sleep time depends on library version and differs from roughly 71 minutes to 3h46.
If you specify a Min sleep time of 0, you'll have to wake the device yourself by pulling RST to GND.
Max sleep time depends on library version and differs from roughly 71 minutes (4294 sec.) to 3h46 for ESP8266, and up to 8 years (281474976 sec.) on ESP32 (theoretically).
If you specify a Min sleep time of 0, you'll have to wake the device yourself by pulling RST to GND. If you specify a negative sleep time value, the maximum will be applied.
