+**************************

+This API enables the System service for the node. It should be called after `RMaker.initNode()` and before `RMaker.start()`.

+* ``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. Value of zero would mean that there won't be any reboot after the reset. Recommended value: 2
