kopp111 That's what our devices do, it works normally even suffer a network down. When there is a network failure, the app's home page will show "Offline". However, the device has saved all the scheduled information and they will still be executed on time. So you don't have to worry about the device not working when it is offline.
BUT!!! Attention please. Smart features, like the Smart Weather Skip function and Smart Schedules, are not available when the device is offline. So when you find that your device is offline, please fix the network problem in time to access all Smart features.
