ecobee's Alexa-powered 4th generation smart thermostat is official as the company has just announced and launched the ecobee4. While a main feature of the new smart thermostat will be using one's voice to manage the in-home temperature and adjust it to be cooler or warmer, the ecobee4 will feature the full functionality of Amazon's Alexa Voice Service too, so the thermostat will also be compatible with every Alexa Skill that you can currently use on the Echo products.
ecobee was rumored to be gearing up for the ecobee4 launch back in April and Alexa being integrated with the device was part of the rumor back then, but as it was just a rumor it wasn't confirmed by ecobee themselves. Right now it's possible to pre-order the ecobee4 and it's possible to place your pre-orders via Amazon, though you can also place a pre-order via ecobee's official website too if this is your preferred location to buy it.
The cost of the ecobee4 will be $249, and if you aren't keen on purchasing the thermostat through either of the above-mentioned websites, ecobee will also be selling the ecobee4 through Lowes as well as Home Depot and Best Buy, though you'll need to wait until May 15th if you want to pick it up in store physically. Additionally you can also do pre-orders for all five of the retailers mentioned here starting from today through their online stores. Alongside the ecobee4, the company is also introducing a new smart home product. This will be a smart voice-enabled light switch and is also powered by the Alexa Voice Service, so users will be able to speak to the light switch as well for all Alexa-related skills, but also to turn off and turn on the lights so you won't have to get up to adjust them. ecobee hasn't confirmed a concrete date yet for the smart light switch but they have said that it will launch sometime later this year. This could mean it will launch sometime this Summer or it could be further out thanks to the lack of a specific date. The cost of the switch is also a mystery for now, but as it gets closer to the launch and pre-order availability ecobee will probably share pricing details.
