Armac UPS uses trinary logic. Sometimes.

[blaa]

Hello.

I've placed my UPS in it's new destination and it seems to be using internal autotrafo to decrease the voltage. Probably. It reads 247V and outputs 214V. AUTO icon is enabled on the screen.

BUT. This seems to create new type of message which kills bit parsing:

I'll probably look into it later and maybe create a patch to support this, but wanted an issue to anchor the problem somewhere and be able to gather info.

Thanks for the report, and a PR would be much appreciated :)
