I hope that when the time comes for me to use my phone to command my bath to start running as I am driving home, that 10 minutes later it automatically calls the plumber, plasterer and electrician to sort out the damaged caused by the flood after I forgot to "end task".
TBH, the only times I use my phone for something similar, is to control my sonos wireless music system around the house, and only then because the dedicated remote from sonos costs a couple of hundred quid, whereas the app is free.
As I go to bed, on my way out of the living room I reach out and switch the light out as I walk past the switch, I had already completed the onerous task of picking up the remote from the side table next to me to switch off the TV.
Living in Northern England, I often find myself gazing southwards in jealousy at the automation that exists across the divide in southern England, but console myself knowing that they drink beer with no head and normally a sissy "top" of lemonade to help their delicate throats as they drink it. 🙂
