Smart Outlet Reference Design (RD-0051-0201) Kit User's Guide
Introduction
1. Introduction
There is an increasing desire in the market for a standards-driven, low-cost, and low-power wireless home automation system. For
many entrant systems a smart outlet is usually employed to remotely activate and deactivate the source power feeding into room
lamps, personal fans, and consumer electronics. In addition to home automation, consumers are employing an array of low-cost sensors to further enhance their home automation’s autonomous behavior. Silicon Labs has developed a compact and cost-effective smart
outlet reference design targeted at these applications. This reference design (see the following figure) features Silicon Labs’
EFR32MG1P232F256GM48 ZigBee Pro Wireless Microcontroller (MCU), the Si7021 temperature and relative humidity sensor. and the
Si1141 ambient light sensor. The outlet also features voltage, current, and power measurement capability, as well as current and thermal overload shutdown features. The reference design can be directly integrated into a connected ZigBee home automation application, as shown in Figure 1.2 ZigBee Home Automation with Smart Outlets on page 1. The reference design comes preprogrammed
and fully functional out of the box. All hardware design files and firmware application source code are available.

Quick Start Demonstration
2. Quick Start Demonstration
A video showing the quick-start demonstration is available at http://www.silabs.com/zigbeesmartoutlet.
1. Set up an HA 1.2 ZigBee gateway.
2. Supply power to the ZigBee Smart Outlet.
a. Ensure the reference design is connected to a main power source. Note that the outlet power supply is rated to 240 VAC,
however, the the North American plug is rated to 120 VAC.
b. The reference design is powered when the green LED momentarily flashes at least once.
3. Connect the ZigBee Smart Outlet to the ZigBee network.
a. Follow the directions provided with the ZigBee gateway to enable the smart outlet reference design to join its ZigBee network.
b. Depress and hold external front button for more than three seconds, then release to begin the network join procedure.
c. The outlet has joined the ZigBee network when the green LED blinks six times.
4. Demonstrate ZigBee Smart Outlet functionality.
a. Send an “on” command from the gateway to the smart outlet. This should cause an audible click to occur (from the internal
relay), the red LED will blink once and power will be applied to the front female plug outlet.
b. Send an “off” command from the gateway to the smart outlet. This should cause an audible click to occur (from the internal
relay), the red LED will blink once and power will be removed to the front female plug outlet.
c. To manually provide or remove power from the female front outlet, hold the front button for more than half a second, but less
than two seconds to toggle between states.
d. If supported by the gateway, the on-board sensors on the reference design can be viewed by the user interface of the gate-
way.

Recommended Next Steps
3. Recommended Next Steps
A video showing the recommended next steps is available at http://www.silabs.com/zigbeesmartoutlet.
3.1 Evaluate the Smart Outlet
The ZigBee smart outlet reference design can support most smart power outlet application requirements. Typical areas of evaluation
include:
1. ZigBee network behavior, such as network join and leave.
2. Deploying on-off commands remotely.
3. Measuring energy consumption of the controlled load.
4. Monitoring ambient temperature, humidity, and ambient light.
5. RF performance, such as range.
3.2 Evaluate the Firmware
If firmware modification is needed to support your application:
1. Visit the ZigBee Getting Started page and order a development kit.
2. Refer to Section 7. Firmware of this document.
3.3 Build Proof of Concept
Out of the box, the smart outlet reference design can be used for a rapid proof of concept. One can demonstrate the look, feel, and
function of a final product. Refer to Section 7. Firmware to change functional behavior, such as LED blinking or button functionality.
3.4 System Integration
Section 6. Hardware of this document describes the considerations for integrating the reference design into a typical application. Often
the reference design can be designed into a system without modification. In cases where a change is required, the hardware section of
this document also offers modification guidelines.
3.5 Engineering and Manufacturing Tests
Section 9. Engineering Tests of this document provides engineering test information for UL, such as FCC and HA 1.2.
Section 10. Manufacturing Tests of this document offers considerations for simplified manufacturing tests.
3.6 Manufacturing
Please contact Silicon Labs to access our manufacturing partner network for the reference design, or a modified version of the design.

4.1 Part Numbers
The part number convention is RD-XXXX-YYYY, where:
RD Reference Design
XXXX Reference Design Number
YYYY Reference Design Component
This document will use the reference design number (RD-XXXX) when describing the complete design, and the reference design component (RD-XXXX-YYYY) when describing a specific component.
The following table provides a description and PCB marking for each part number.
Note: Some cases lack sufficient space on the PCB, and an internal “IST” marking appears on the PCB instead of the “RD” part number.
