Hi kata,

The device requires a WiFi connection. As a workaround, we recommend pre-setting schedules via WiFi in advance: Before taking the device to the rental house, connect it to WiFi through the app, set up all necessary watering schedules, and save them.

If the device previously had a scheduled watering program set up, it will continue to operate even after going offline for a month, as the device can store 128 watering programs. When the device is offline, it will retrieve watering programs for the next 30 days from the current date, with a maximum of 128 programs. However, once these stored programs are executed, no further scheduling will occur.

Thanks,

Netro Support
