The ecobee3 lite thermostat can be easily controlled right from your iOS or Android device using the free app, as well as via Siri and Amazon's Alexa. In fact, it links in great with pretty much all smart home ecosystems including Apple HomeKit, Google Assistant, Microsoft Cortana, Samsung SmartThings, Wink, and IFTTT.
