Google Nest Community

I've downloaded the Home app but as far as I can see, you can't use it to control hot water. I'm completely baffled by this. All those thousands of people with heating and/or hot water on for longer than they need it, paying more, putting more carbon...

Thanks. Does it work for hot water control? 

I'm another new customer who is astonished that I can't set my water or heating at 15 minute increments. First day with the Nest thermostat, big disappointment.
