UG171: ZigBee
Design (RD-0051-0201) Kit User's Guide
Silicon Labs' compact and cost-effective smart outlet reference design is based on Zig-
Bee HA (Home Automation) 1.2 standard and can be used in conjunction with a ZigBee
HA 1.2 home automation system. This reference design kit features Silicon Labs'
EFR32MG1P232F256GM48 ZigBee Pro Wireless Microcontroller (MCU), the Si7021
temperature and relative humidity sensor, and the Si1141 ambient light sensor. This
document contains instructions and guidelines for the following: a quick-start demon-
stration and next steps, system overview and operations, hardware and firmware con-
siderations, and engineering and manufacturing testing.
This guide applies to EmberZNet PRO 5.8 and later.

  • Page 8: Operation

    5.1.1 Remote Control The ZigBee smart outlet reference design utilizes a 15A controllable relay to manually or remotely toggle power to a device connected to the front female outlet of the device. If it receives an “on” command from the gateway it will close the relay contact to supply power to the load.
  • Page 9 This section describes the various operational states that the smart outlet reference design is able to occupy as it joins and leaves a ZigBee network. The input mechanism for operation utilizes the external push button. The green LED and red LED operates as output signaling information as the reference design traverses or occupies a functional state.
  • Page 10 5.2.5 ON-NETWORK State The ON-NETWORK state is a condition where the smart outlet reference design is connected to a ZigBee network and is not searching for another network. This state contains multiple entry and exit paths depending on various factors.

Manufacturing Library CLI To assist with the manufacturing process, the occupancy sensor reference designs include the manufacturing library as well as the manufacturing library CLI commands.
  • Page 15 Theory of operation Silicon Laboratories has created a custom ZigBee cluster that provides RF commands for the purpose of putting the device receiving the commands into manufacturing test mode. Specifically, it can force the device to transmit an unmodulated tone, transmit a modula- ted tone, or receive packets for a short time to check the TX or RX path of the device in the field.
  • Page 16 ® UG171: ZigBee Smart Outlet Reference Design (RD-0051-0201) Kit User's Guide Firmware Here is an example of the commands used to command the reference design to transmit a modulated carrier at channel 15 with a pow- er of 13 dBm until the next device power cycle.

  • Page 17: Ecosystem Considerations

    8. Ecosystem Considerations In this reference design the firmware examples are ZigBee HA certifiable. As such, they should work with any of the ZigBee-certified Home Automation gateways in the market. However, each gateway may have some individual requirements beyond the ZigBee Home Automation requirements.

  • Page 18: Engineering Tests

    • Underwriter's Laboratory (UL) 9.1 ZigBee Home Automation HA v1.2 The outlet reference design went through a preliminary HA 1.2 testing to verify compliance with the ZigBee standard. 9.2 FCC Emissions Testing This design went through a preliminary FCC pre-scan testing to verify compliance with FCC Part 15 restrictions. Such testing is done to ensure customers are given a design that can pass FCC tests.
