The Hive Mini is much smaller, slimmer and more stylish than the regular Hive Thermostat and yet, aside from a couple of small restrictions, it does largely the same job. We found the system performed well overall, especially in conjunction with Hive’s smart radiator valves, and was easy to use. Millivolt Heating Systems: A millivolt heating system can be a wall-mounted or floor-mounted heater that is powered by natural gas or electricity. Even when a millivolt system uses electricity, it still provides less power than the required amount for the Nest thermostat. It certainly doesn’t have the bells and whistles of other thermostats on this list, but this is a cheap, cheerful and effective entry point into the world of smart heating.

As far as the learning thermostats settings go, I’m happy with it. I find myself adjusting the temp less, though I nearly always want it set at a certain temp at a certain time so could easily get by with a schedule. I could see how this setting could become a nuisance if you are one to change the temp constantly at various times without some sort of pattern. For us, it took about 5-7 days before the temp was automatically changing.But for Nest Thermostat E and Nest Learning Thermostat, the batteries are built-in, and they charge automatically via your HVAC system.
