Ooh I’ve got a similar trigger! Instead of coloured lights, mine strobe every five minutes incessantly until I open the machine door (power usage goes down ~3W for some reason). Also notify the phones and put a banner on the TV.
Not overly high tech but such a good fit for the culture and extremely convenient:
Self-filling, self-warming baths
Put the plug in during the day, press the button to fill the bath at the remote keypad in the kitchen. Baths fills and a little jingle announces that the bath is ready at the perfect temperature.
It’s been about ten years since sports betting advertising has been permitted on TV in most Australian states. It has pervaded everything and made betting a normalised part of sport.
Most people hate it and want it gone, but clubs and networks are drunk off the money it provides so governments have been slow to move.
Please if your country doesn’t allow sports betting ads yet, put up a fight to stop it.
Sometimes it’s better to reply in comments to address specific questions, other times better to post an ETA. Sometimes, I just wanted to provoke discussion, or I’m about to do something that’ll leave me away for a couple of hours.
