Hmm, not sure if this is similar to software we have seen before.

Technically, one star is "protocol based on reverse engineering" (key is at the top of the page) but the ratings are somewhat subjective beyond that (some protocols are easier to understand than others).

There are some pointers in the list archives (also check nut-upsdev). It's certainly up to you as to how you want to approach this, but we do see a lot of commonality in the protocols - so feel free to post updates as you go along. There is a good chance that the protocol is similar to another driver, but that driver may have failed to detect that protocol variant.
