Duo v2: Including other drivers for NUT (Network UPS Tools)?

There are a number of different ways serial-to-usb is done requiring different drivers. Too complicated to support. Anyway for quite some time now a very good range of UPS units with USB ports have been readily available.

Hmm, I have a feeling that you misunderstood me here. Just to clarify things, the Network UPS Tools suite provides a generalized abstraction for ups monitoring daemons/monitors to query ups capabilities and be notified of power-related events, regardless of the underlying hardware, be it serial/usb/hybrid. To accomplish that, NUT is composed of two parts: the abstracted, high-level layer, which is already in our readynas units, as well as a lower-level layer that is specific for a given ups family. For the latter, NUT already includes drivers for a vast number of ups families, hidups (already included in readynas) and powerpanel (not included) being two of them. It's because not all the drivers are included, that I cannot configure the nas box for my own ups type/brand.

Bottomline: to include support for powerpanel-based ups's there's no need to modify readynas in an extensive way. Just include the powerpanel NUT driver and other NUT drivers. IOW, generate all NUT drivers, when compiling NUT for readynas, piece of cake! What does require some work (and then some) is modifying the readynas interface to provide a new pull down menu for the user to select a ups type (essentially, a NUT driver), plus provide a box for customizations...

That's some work, if you ask me. Another alternative, much simpler for netgear, is to compile and provide all the NUT drivers, but without catering for ups types other than hidups, from the user interface. At least, a user could modify /etc/nut/ups.conf to it tailored for his/her UPS model.

If you have another linux box, I could provide help to test a client/server setup for NUT :)
