How Bluetooth changes the job

A plain thermo-hygrometer shows its readings on its own display, where it sits. A Bluetooth thermo-hygrometer sends readings to a phone or a hub, so the readings can be checked from another room, logged over time, or watched remotely. The sensor is the same job; the radio changes where the readings can be seen.

Ask about measurement range and accuracy, update interval, wireless range through walls, and how readings are stored when the receiving device is away. Those figures are not stated on this site.
