What to know before buying

Listing details to confirm

The listing calls this a Bluetooth monitor and says Wi-Fi and app functions require a hub. It also gives two different temperature accuracy entries, 1 °C and plus_minus_0_point_5_degrees_celsius. Battery life is stated as up to 12 months, while the battery description only says rechargeable. Verify which temperature accuracy applies and check hub compatibility and the selected listing's configuration before buying. The title mentions two-year data storage, while the detailed claim distinguishes 38 days of local storage from 2 years of app storage.
