Smart thermostat
Smart thermostats are thermostats that can be used with home automation and are responsible for controlling a home's heating and/or air conditioning. They perform similar functions as a Programmable thermostat as they allow the user to control the temperature of their home throughout the day using a schedule, but also contain additional features, such as sensors and WiFi connectivity, that improve upon the issues with programmable thermostats,
BT Smart Hub
The BT Smart Hub (formerly BT Home Hub) is a family of wireless residential gateway router modems distributed by BT for use with their own products and services and those of wholesale resellers (i.e. LLUs) but not with other Internet services. Since v 5 Home/Smart Hubs support the faster Wi-Fi 802.11ac standard, in addition to the 802.11b/g/n standards. All models of the Home Hub prior to Home Hub 3 support VoIP Internet telephony via BT's Broadband Talk service, and are compatible with DECT telephone handsets. Since the Home Hub 4, all models have been dual band (i.e. both 2.4GHz and 5GHz).
