Johnson Controls'GLASsmart thermostat is probably the most lovely smart thermostat you can get right now. It has a dual-array microphone and a speaker for Cortana feedback, and runs Windows 10 IoT Core inside on a Snapdragon 410E processor with WiFi and Bluetooth. Over time, the device will learn to detect when someone is or is not home and adjust settings accordingly.
A rather lovely and futuristic looking OLED glass touchscreen displays a neat and slick user interface which offers one way to interact with the thermostat, but it can also be controlled with voice commands. That's a steep price even in the context of smart thermostats from rivals like the Nest Learning thermostat, which costs $249/£279 (around AU$317), but in this case looks are every bit as part of the appeal as function. You can also use it to manage your calendar, check the weather, traffic reports, and pretty much anything else that Cortana can do.
The device itself will continually monitor air quality and adjust settings for it, as long as it's connected to the internet. It will be interesting to see if the Cortana-powered smart thermostat can compete with similar products that work with Alexa, Google Assistant or Siri. It's also compatible with virtually all types of 24VAC heating and cooling systems, so you should be able to install it in your home or office with few complications. An auxiliary output can control humidifiers, dehumidifiers, ventilators, energy recovery ventilators, or heat recovery ventilators.
Preorders will be available from March 2018, with Johnson Controls saying GLAS should ship sometime in Q1 2018. It's priced at $319.
