Smart home accessory specialist Ecobee unveiled two new smart thermostats Tuesday. Smart Thermostat Premium and Smart Thermostat Enhanced offer larger displays than before, a redesigned interface, HomeKit integration and more.

It appears Ecobee, the Canadian smart home accessories maker, will soon release a new version of its SmartThermostat with an air-quality sensor built right in.

The leak of the upcoming product came in the form of a hidden image in an update to the company’s iOS app.
