Ecobee, a company best known for its line of smart thermostats, may be working on a video doorbell. A leaked image from ZatzNotFunny shows what looks like an Ecobee branded video doorbell with rounded corners and a blue button.

As noted by ZatzNotFunny, the doorbell has a green status light and two small holes, one of which may be a microphone, placed directly below the camera. The overall design seems to take elements from existing doorbells on the market, such as the bright blue light used by Amazon-owned Ring and Blink and the rounded edges on Arlo and Nest devices.

But other than this one photo, we don’t know much else about the device, including whether it will be wired or battery powered. The doorbell likely supports Apple HomeKit, Amazon Alexa, and Google Assistant. Ecobee’s existing line of smart thermostats and smart security cameras already come with integrations for: all three systems (and more).
