If you develop with LabVIEW or a similar program, you use this app when you are concerned about being down in the field.Please update the title of the html file on the server in real time by using FTP in the LabVIEW code.And if you register the corresponding html address in the app input box, the app continues to check the title (Data) information and monitors whether the field program works normally.However, since the notification level was developed lightly, the notification level may be weak when the app is turned off or the phone is turned off. Therefore, if checking whether a program works in real time is very important, please keep your phone and apps on at all times.For more information, see the video at https://www.youtube.com/user/ok2401/.
