Dear customer,

Wifi connection is required the set up the Spark controller.

When the device is online, netro will pull and save normal schedules. When the device is offline, it will continue to execute the normal schedules that was pulled down previously. After the normal schedules are all executed, it will generate a backup program if the backup program is saved.
Please also note that when creating a backup program, the device must be online.

Thanks,

Wency
