Ecobee4

$ 249 Ecobees receive most of the best things from Ecobees, the most experienced indoor controller. It has a sensitive touchscreen, proximity sensor and district heating, intuitive and versatile applications and integration with Amazon Alexa, Apple HomeKit, Samsung SmartThings and IFTTT. Instead of working with Alexa, Ecobee4 is an Amazon speaker. (Ecobee4 is only available in the United States, the current conversion rate is usually spoken by £ 190 / AU $ 330.)

Ecobee4 does not work exclusively, it's the smartest internal controller we've ever seen. That's why we offer you a CNET Editors Choice Award. If you do not need it intelligently (or if you have an Alexa speaker) then consider using one of Ecobee's affordable dimmers or Honeywell's $ 150 Lyric T5. Otherwise, I would definitely recommend Ecobee4.
