Returned from holiday to a cold house. Why? Hive heating still in holiday mode. Why? Hub not connected. Why? Network down. Why? Power cut while away fried one of my powerline adapters.
Very much an "I have overcomplicated my home" problem.
@targetdrone Ah, but the "smart" part is that you can tell it to come back on before you get back, and therefore the house should be warm.
Wife is somewhat equivocal about debatably-useful magic box anyway, so house not being warm results in a slightly grumpy wife. This is worse than a cold house. ;-)
