I have an in-floor hot water radiant heat system with multiple zones in a vacation home in the mountains. Each zone is controlled by its own Nest Learning thermostat. I would like to set the Nest app up so that I can manually select Home or Away and have all thermostats heat to the selected Home or Away temperature. It seems I can set an Eco temp for each zone, but then my options to enter Home or Away modes are either "phone location" or "thermostat motion sensor". Since radiant heat takes a while to heat a house, I would like to be able to switch the house to Home several hours in advance, using the app. Is there an easy way to set this up? I seem to only see the "phone" or "room" option, both of which will start the warmup only when I arrive. Thanks for any thoughts on this subject.
