I am hoping to get into smart themostats, to see if this can help me save some of the heating in my home. Its a family of 6, 3 storey building and we are in and out and wake up at very different times and can see a case for smart themostats like hive, toda etc. I would have prefered Google nest but having done a bit of research, I understand this does not come with the ability to control individual rooms. So just wanted to check what are you using and why please?.
