Smart thermostat
Another major feature of smart thermostats is their ability to connect to the internet. Smart thermostats are designed with a WiFi module that allows the thermostat to connect to the users home or office network and interface with a web portal or smartphone application, allowing users to control the unit remotely. The WiFi feature also has the ability to send reports on energy usage and HVAC system performance via the web portal, informing the user on their energy efficiency and how it compares to other smart thermostat users. It also alerts users when a problem arises with their HVAC system or when it is time for equipment maintenance. The thermostat also uses the WiFi connection to display current weather conditions and the weather forecast.
Xiaomi Smart Home
Xiaomi unveiled the Smart Home Kit for CNY 199 on 10 June 2015. The kit contains a set of smart sensors, including the multi-function gateway, the door/window sensor, the motion detector and the wireless switch, which can be combined to achieve over 30 different kinds of functions. For example, the motion detector can be paired with the gateway to perform functions such as switching on a light at night when it detects motion; the window sensors can start or stop a connected fan as windows are closed or opened; in another example, users can set the gateway into alert mode with their smartphones as they leave the house, and the gateway would then send push notifications and turn on the automatic recording of a Yi Smart Webcam when the door/window sensor or the motion detector detects abnormal activity.
