This app can only be used in combination with the paid web application of the SPIE Energy Manager. With the SPIE Energy Manager Mobile App, it's easy to read meter readings and transfer them to the database. The meter reading is offline. The transfer of meter data to the database can be done at any time after the Internet connection is available. You will be supported in the meter reading by a camera-based read-in method (OCR). You can both edit reading lists and make direct readings.
