I always though Agas were on all the time, but I've learnt from these very pages that's the old ones. It woud appear the newer 'leccy ones are a different beast.
I'm not a great fan of all this IoT stuff, for the usual reasons. Can't say I'd ever really want to switch my cooker on when I wasn't there. I don't like having such appliances on when I can't keep an eye (or nose) on things.
