What to know before buying

Listing details to confirm

Listing details are inconsistent on accuracy: the specifications give a temperature accuracy of 0.5 degrees_celsius, while the feature claim states ±0.9℉/±5%RH. The details also list wall mounting, while the feature text additionally mentions kick-standing and hanging. Confirm the relevant accuracy and mounting options for the selected listing. Bluetooth app use and alerts require connecting the device to the app, and the listing describes Bluetooth rather than Wi-Fi connectivity.
