Answer Description

Smart thermostats typically connect to the internet through a Wi-Fi connection, enabling remote access and control through a smartphone app. Bluetooth is generally used for close-range connections, not for remote access. NFC is more commonly used for contactless payments, and IR is used for remote controls that require a direct line of sight and are not internet-enabled.
