+**************************
+
+This API enables the System service for the node. It should be called after `RMaker.initNode()` and before `RMaker.start()`.
+For more information, check `here <https://rainmaker.espressif.com/docs/sys-service.html>`__.

+* ``flags`` : Logical OR of system service flags (SYSTEM_SERV_FLAG_REBOOT, SYSTEM_SERV_FLAG_FACTORY_RESET, SYSTEM_SERV_FLAG_WIFI_RESET) as required or SYSTEM_SERV_FLAGS_ALL. 
+* ``reboot_seconds`` Time in seconds after which the device should reboot. Recommended value: 2
+* ``reset_seconds`` Time in seconds after which the device should reset(Wi-Fi or Factory). Recommended value: 2
+* ``reset_reboot_seconds`` Time in seconds after which the device should reboot after it has been reset. Zero as a value would mean there won't be any reboot after the reset. Recommended value: 2
