Re: Smart heating system?
A good number of people, as they are driving to the airport for a family holiday, are haunted by thoughts of 'Did I leave the gas / iron / heating on?'
The ability to check and remotely turn off such things would bring peace of mind to many individuals.
Of course many people are friends with their neighbours and leave them a key. Others folk though, perhaps new to to an area, or too busy, haven't built that level of trust.
