With the ecobee3 and HomeKit, your home comfort goes up as your energy bills go down.

ecobee makes a smart thermostat that connects to your existing central heating, ventilation, and air-conditioning system and then connects that system to your iPhone or iPad. Now the company is launching a new version of the ecobee3 hardware that's also enabled for HomeKit, which adds support for scheduled and triggered actions, and for voice control via Apple's Siri virtual personal assistant.

When asked what HomeKit brought to the smarter thermostat, ecobee told iMore:

The popularity of iPhones illustrates why HomeKit has so much potential. Over half our customer base uses their smart phone to monitor and control their ecobee every day, and now it will be that much better by enabling it to work in concert with other HomeKit connected devices.

The new, HomeKit-enabled version of ecobee3 will be available in July from the Apple Store. Pricing remains $249 for the thermostat and a starter sensor, and $79 for a pair of additional sensors.

iMore recently took a look at installing and setting up the current ecobee3, and we've also put together a full HomeKit explainer for the technical details, and a HomeKit FAQ to answer the most common questions.

Available at Apple Stores in July

TORONTO (June 2, 2015) –– ecobee Inc. today announced that the ecobee3 smarter wifi thermostat now supports Apple HomeKit, allowing users to better manage their environment and ensure comfort where it matters most in their home. The beautifully designed and smart ecobee3, from the maker of the world's first wifi connected smart thermostat, is the first smart thermostat built with HomeKit support and will be available at Apple Stores in July.

"As the first HomeKit-enabled smart thermostat, we couldn't be happier to bring this revolutionary technology to customers," said Stuart Lombard, president and CEO of ecobee. "The new ecobee3 uses wireless remote sensors to deliver the right temperature to the rooms that matter most, and now customers can conveniently control their temperature using Siri on their iPhone, iPad or iPod touch, or the ecobee app."

Designed for homes with more than one room, the ecobee3 smarter wifi thermostat and remote sensors measure temperature and occupancy in multiple locations, resulting in increased comfort when you're home and energy savings when you're away. The sleek and functional ecobee3 addresses varying temperatures and begins conserving energy to deliver savings immediately after installation. The ecobee3 saves homeowners an average of 23 percent on their heating and cooling bills.
