An excellent tip about the plug-meter, thanks! I had no idea.
If anyone sees any reliable big bang-for-the buck units then I would be glad of further tips.
Actually, apart from possible mains droops or spikes or brownouts, but I wouldn't know about those anyway, as I do not have logging thereof, we do not get short power cuts. So it is always generator on, except that now my poor wife always tries to make up some lame excuse that we do not need to bother with electricity, to cover up the fact that she can't start the generator. Bless her and big kiss in her direction, wish her hands were better. So we really need an appropriate generator now, it is all about time-to-get-generator-started too.
