I'd really like this UPS to interface with NUT so that I can use a
variety of tools to monitor it, such as Nagios and cacti, etc... I
really don't want to have to write my own driver for NUT if I can
avoid doing so, so the main question is which serial interface is the
most sane for me to implement in my controller. The megatec driver
seems to be one of the most popular but I can't find much
documentation about the protocol.
I don't think this is the most suitable protocol, but nevertheless:

Thanks for the link - I had seen this before but I'm not sure if it
conveys the whole picture. I guess I can always read the megatec driver
source to figure out what it wants to do :-)
But if it isn't the most suitable driver, do you have a better one in mind?
In addition I'm wondering how much NUT looks at various parameters
like input / battery / line voltage, since in my case it would be
12-18V and not the more common 110/230V. :-)
NUT basically only really cares about the flags in 'ups.status', all
other variables are just bells-and-whistles and will not be used to
determine when it is time to shutdown. So the values of input-,
output- and battery voltage are irrelevant, they will be relayed as is.
I thought as much, but it's good to have this confirmed. Thanks.
Cheers,
Chris
