Smart thermostat maker ecobee is teasing its upcoming ecobee4, which is set to debut on May 3rd. The new model is rumored to include a built-in microphone and speaker with Amazon Alexa voice control built-in. ecobee4 will reportedly have a sleeker, yet familiar, design and the separate room sensors are said to be silver instead of white. The company also lowered the ecobee3 price ahead of next week’s announcement from US$249 to $199. That’s a pretty sweet deal for a full-features smart thermostat that’s also HomeKit compatible. If you want to follow along with ecobee’s announcements next Wednesday you’ll need to head over to the company’s Facebook page.
