Well, looking at online documentation for this device, it looks like  
the UPS is able to report these values on the build in LCD display. In  
most cases, this means that you can also read this from the device  
through the monitoring interface. The bad news here is, that currently  
the metasys driver doesn't seem to handle this in any way.

Worse, short of some general fixes regarding changes in NUT, nobody  
has touched this driver for at least four years. I'm not even sure if  
the original author of this driver is still involved with NUT and/or  
still has access to a device for testing. I've put him on the CC list  
anyway, so we'll see if he is willing/able to add this to the driver.

Best regards, Arjen
