Hi Kyle.
Currently we only have notification for users about device is offline but you need to enable Netro App notification in your smart phone settings.
Netro always keep one month schedule on local and can keep water your yard up to one month without wifi.
We just checked your account and we found you preferred watering time is 12 am ~ 5am. Netro keeps watering outside your preferred watering time because Netro thinks the smart watering is not enough. To strictly restrict watering to a certain period, please go to Settings->Restrictions to add a restriction.
Regards,
Netro Support
