What is done in India is not likely the same as what is done in the UK.
Automation can help, but also it can switch on the wrong things, hey google turn on Linda's spot can instead of turning on one light, can turn on all in the living room, which is in a way OK, as I know it has happened, so can also turn off all, and start again. But having a out side light turn on, one may be unaware.
Again not so bad, but turn on my AC or oil filled heater, that could cause a bit of a bill, so I try to program in an off, timed with lights during the day, but to just say automation is good is not true.
