Central Heating Controls

I've been doing some research on central heating and hot water controllers, and the possible benefits in reduced energy consumption that they might offer. Here's my summary of some of the products available in the UK:

     Google Nest Thermostat

     Tado Smart Thermostat

     Honeywell Evohome

     British Gas Hive Active Heating

     Owl Intuition-hw

     Heat Genius

And the features that they each offer are:

Single zone control
     Nest Thermostat
     Tado Thermostat
     Hive Active Heating
     Evohome
     Intuition-hw
     Heat Genius

Remote Monitoring and Control via the Internet or Smartphone
     Nest Thermostat
     Tado Thermostat
     Hive Active Heating
     Evohome
     Intuition-hw
     Heat Genius

Anti-Frost Protection
     Nest Thermostat
     Tado Thermostat
     Hive Active Heating
     Evohome
     Intuition-hw
     Heat Genius

Multi zone control of individual radiators
     Evohome
     Heat Genius

Hot water control
     Evohome
     Heat Genius

Pre-Heat via Geofence
     Tado Thermostat

Pre-Heat via Weather Forecast
     Tado Thermostat
     Heat Genius

Auto Away via Geofence
     Tado Thermostat

Auto Away via Motion Detection
     Nest Thermostat
     Heat Genius

Adaptive Timer via Motion Detection
     Nest Thermostat
     Heat Genius

So, in summary, you can't have all the features in a single system. The Heat Genius system comes closest, just lacking the geofence feature of the Tado to enable the system to pre-warm your home prior to your arrival.
