Well that’s the thing. You design around your needs.

We have leak sensors on the brew fridge downstairs and behind the washing machine so we catch issues before they become floods. Door sensors to assuage anxiety and handle ADHD. Smart sockets so we can turn on things like rope lights in the subfloor with a button we can place anywhere we like rather than groping twelve feet into the spider-filled space to find the GPO. A button where every single function is set to turn the fan on so the hubs can roll over and slap it on his bedside table when he wakes up too hot instead of reaching behind the fan half asleep and fumbling for knobs. A tea button so we don’t forget the tea we have steeping. Tank overflow system that overrides the daily timer and pumps to a secondary reservoir system to maximise capture in high rainfall. Stuff like that

The speaker that plays “it’s raining men” when his lordship comes home and the garage door sensors that scream “what is WRONG with you people???” If opened at 3am is just me having fun with it though
