I. Device Information 

 

The Power Reader is a metering device capable of counting pulses from any electricity 

or  gas  meters.  The  device  stores  timestamped  consumption  in  its  internal  memory  every  15 
minutes. 

Note: 

The Power Reader for electricity metering has different firmware than the Power Reader 

for gas metering. Please make sure you have the appropriate firmware on your device before 
you start integrating / installing it. The proper way of distinguishing between the two firmware 
versions is by using the MANUFACTURER SPECIFIC command class.
