Optimize your living or working quarters by installing some CubeSensors ($250-$350). These small cordless boxes continuously measure temperature humidity, noise, light, air quality, and barometric pressure and send all that data to the cloud so you can access it anywhere. Thanks to an intelligent app, they can send you alerts letting you know when it’s time to turn on the lights, aerate, humidify, crank the A/C, and more. Available in a starter pack with a base station and either two or four included sensors.
