Hello everybody, so, here's the summary of my progress (note that it also includes a few items to discuss, so I'm cc-ing this to nut-upsdev as well). I. The planning: 1/ libnutconf: The core (i.e. config. classes and their (de)serialisers) is coded, UT in progress. Signalisation shall follow; I have a couple of practical thoughts & comments to this, see below. In general, I'd like to have libnutconf core UT-ed this week and the signal handling coded at the very lea...

...d the archives, and although I've come close to finding a few things that describe my problem, I haven't been able to nail it down. Basically I've got 8 TrippLite SU3000RTXR3U's (Couldn't it be a simple model number, like "4UPS"? hah!), and when I tap in to them with nutc, I see that the status flaps back and forth between OL and OB quite frequently, to the tune of several times a minute. I see that the power coming in is clean and not fluctuating at all, and none of my other UPSs do this, even those that nut is monitoring. I suspect some sort of bug in the firmwa...

...fig. files (or possibly other config. resources). The vision is that using a set of such high-level libraries, NUT will become an open framework (or platform, if you prefer) for further development of more complex power control solutions. (I hope I've formulated that, well.) Now, the (C++) libnutconf library design and development was started by Emilien K. some months ago; during the last month or so, I continued on the implementation, culminating these days by announcing that the core is basically coded. The library now contains an I/O layer, allowing synchronous access to configuration da...
