Use case – deploying home automation
Typical home automation deployments provide a combination of the following feature sets:
- Controlling and monitoring appliances, such as air conditioners, refrigerators, or heaters
- The controlling of lights (on/off, a change of color or brightness, or on/off based on a person’s presence)
- An action based on a detected event (for example, an alarm/buzzer sounding when smoke is detected)
- The remote operation of doors and windows
- The detection of an intruder that triggers an alarm
- Conversations with smart speakers
The following figure gives a representational view of home automation implementation:

As you can see, devices that are battery-operated and have low bandwidth requirements typically transfer data on an energy-efficient protocol (for example, Zigbee), whereas devices such as a video camera send the data...
