The ZigBee Remote Control (ZRC) is a simple, non-meshing network optimized for User Interface products like remote controls. Both ZigBee Remote Control and ZigBee Home Automation devices use the same radio technology (IEEE 802.15.4); however, ZRC is designed to be a simpler network, requiring less system resources, resulting in lower cost solutions.
You can use the ZRC for a number of different applications. It can be used for simple remote controls to control a single device, or more complex scenarios where it’s used to control not only different devices, but also different types of devices. An example of this would be Audio/Video devices and Home Automation devices. Let’s look at two applications for the ZRC.
ZigBee Remote Control Network – In this case we have the ZRC remote control communicating with a Set Top Box (or any Audio/Video device). The remote is used to change channels, control the DVR, etc., but it can also be used for 2-way communication to enable features such as “find my remote” and downloading IR codes directly to the remote control for controlling legacy IR devices such as TVs.
ZigBee ZRC / Home Automation Multi-Network Device – In this use case, we see two popular ZigBee applications, ZigBee Remote Control and ZigBee Home Automation, overlapping to allow communication from different networks. Through a ZRC/HA multi-network device, such as a Set Top Box, the user can also control HA devices from the ZRC remote control, for example, adjust the thermostat temperature, turn on/off lights and even get status messages directly on the TV. This extends both networks to provide a more complete user experience in the home.
