When maintaining and configuring systems for Automatic Meter Reading (AMR) it is important to have access to powerful tools for on-site management of the connected metering devices. These tools include mobile phone applications which allow system operators to directly manage the devices through the physical interfaces they expose. This thesis report explores and describes the implementation of an application, the problems and choices which arose while developing it, like choice of platform and communication protocols. The result is an Android application that is capable of setting up communication variables on the metering devices and reprogram them with new firmware, amongst many other features.
