SMART THERMOSTATS

NEST THERMOSTAT E

$305, nest.com

This cheaper Nest model doesn’t fit as much information on its screen and doesn’t feel as premium, but that’s it. Same algorithm, same Alexa and Google Home compatibility.

TADO SMART THERMOSTAT

$249, tado.com

Tado is very sociable: it works with 95% of the systems out there. It’s flexible, clever and supports a wide range of accessories too. Price cuts have made it even more enticing.

NEST LEARNING THERMOSTAT

$300, nest.com

Nest made smart thermostats sexy and this third-gen model looks great.

It’s simple to use with good Google Home and Amazon Echo integration, but a tad pricey, especially with installation.

HIVE HEATING CONTROL

$339, hivehome.com

Hive is great: it’s affordable, works well, and is part of a larger smart home system that includes bulbs and security options. This is an ideal way to jump in.
