【Works with Apple HomeKit】Check data via the Home app on your iPhone. With an Apple Home Hub device, you can access data remotely or set automation (iPhone must be upgraded to iOS 15.1 or later, and the hub must be updated to the latest version). With the Qingping+ app, you can export the latest 30-day data. The device transmits the latest data to the hub or phone every 10 minutes. Attention: This product does not work with the Qingping+ app on Android phones, only on iPhones. Accurate Measurements: The built-in Swiss sensor responds with accurate real-time measurements. The measurement range is 0-50°C for temperature and 0-99.9% RH (non-condensing environment) for humidity. Press the back button to switch Fahrenheit/Celsius. Please do not place this product in a humid environment > 90% for long-term use. *To get accurate measurements, after receiving the product, place it in one place for at least 20 minutes, and then check the measurements. 【Smart Design】Multiple mounting options: 1) With the magnetic wall sticker, you can easily attach it to a wall, or detach it. 2) Open the stand on the back of the product, you can place it on a desk; 3) You can attach it to an iron surface (because it has built-in magnets). The HomeKit-enabled sensor can be a nice decoration for the living room, bedroom, greenhouse, or anywhere you like.
