ups.getBatteryRunTime(function(err, minutes) {
  if (err) {
    console.log(err);
    return;
  }

  console.log('Expected battery run time is', minutes, 'minutes');
});

getLastFailCause(callback)

Get the reason for last transfer to battery power.

Arguments

• callback(err, failCause) - Callback function for error/response handling, see the table below for translated causes.

The translated key is available within the library using ups.failCause[#], as shown in the example below.

ups.getLastFailCause(function(err, failCause) {

Notes

Have only implemented a few basic values to begin with, have plans for a few more just need to find some time to add these in.

All the MIBs have been hard coded into this module, for more details see the PowerNet-MIB at ftp://ftp.apc.com/apc/public/software/pnetmib/mib/411/powernet411.mib
