Thanks for the log - apparently we always get valid (apart from
0.191312) but empty replies, not only for index 0x03, but also for the
other queried index (0x0c).
I've re-looked at the logs you posted on GitHub, but I don't see
anything exotic going on there.
Maybe we're missing some sort of handshaking or the like: can you post
the whole captures/logs, right from when you plug the cable till the
communication is established with UPSmart1.5?
