Today, Xiaomi’s Mijia crowdfunding platform announced the Mi Home Bluetooth Hygrothermograph 2. This is a successor to the model that launched last year. The 2nd-gen model comes with a new design and new features. The original Mi Home Bluetooth Hygrothermograph 2 has a round LCD screen but the new model ditches it for a square ultra-low-power screen. The casing itself has rounded corners. The new model ditches the AAA battery for a CR2032 coin battery. Unfortunately, it doesn’t show the battery level as its predecessor does. There is a built-in Swiss Sensirion high-precision temperature + humidity sensor that can detect up to 0.1°C changes in temperature and up to 1% change in humidity. The Mi Home Bluetooth Hygrothermograph 2 can be configured via the Mijia App and has been designed to work with related products such as the air conditioner, the air humidifier, and the heater. All the aforementioned products can begin to work or get turned off at a preset temperature. For example, the air conditioner can be configured to turn on automatically when the indoor temperature increases to a certain level. You can also have the heater kick in if the temperature drops during the night. ...
