1 INTRODUCTION
1.1 Executive Summary
The US Smart Outlet is a radio controlled outlet that can apply or remove power to a device plugged into
its receptacle. It also measures RMS power being utilized by the device being controlled.
The Outlet communicates wirelessly via 802.15.4 ZigBee SE 1.0 protocol, and responds to the ZigBee
Smart Energy commands. It can be controlled via the Tendril Connect Platform through several portals
(consumer, utility, support) for use in home automation and energy monitoring applications. The device is
intended for indoor applications on UL rated 15A circuits.
1.2 About This Specification
This document describes the Outlet minimal requirements for purchase, such as performance,
environmental specifications, and regulatory compliance requirements. This document is created and
maintained by the Engineering and Operations Team.

2.3 Relay
The device uses a latching relay, to retain the state through a device reset following an OTA. If a
standard Normally Closed relay is used, and the device is reset while the relay is open, it will close
momentarily. This is avoided if the relay is latched, and reset will not affect it.

3 Performance Specifications
3.1 Reliability
MCBF Environment
Unit reliability = 500,000 POH (based on component analysis)
Equates to a failure rate of 1.7% per year over the useful service life of 5
years.
Indoor Residential
Switching reliability = 100,000 MCBF operating both relays at 10 A resistive
load Indoor Residential
3.1.1 Reliability Testing
The reliability specification is tested at 120 VAC, 10A load while maintaining ZigBee radio communication.
• The radio shall not reset during device switches.
• ZigBee communication shall not be degraded by a consumer noticeable level during normal
operation.
3.2 Power
3.2.1 Power Source
The unit is powered from a standard US 120 VAC + 10% source @ 50-60Hz. The unit operates over an
input range of 100 to 150 VAC.
3.2.2 Power Consumption
AC Power Consumption is 0.6 W in quiescent state, ranging up to 1.5 W during RF transmission and all
LEDs illuminated. 50ms surges of up to 0.5W additional power draw can occur when relay state changes
are activated.
3.2.3 Noise Rejection
The unit meets ANSI C37.90a Surge Withstand Capability and other immunity requirements as specified
in the agency requirements in Section 7.
Furthermore, no permanent damage to the unit will occur if noise on the AC power line is below the
following specifications:
• Motor noise spikes of an extra 30V peak on top of the nominal AC line voltage and frequency
3.2.4 Power Cycling
The unit shall perform without failure through 3600 power cycles. This is based on a use case of 2 power
cycles/day over 5 years.
Testing to validate this spec is done by cycling power for 5 seconds on, 30 seconds off, repeated 7200
cycles on a population of 4 units. This provides ~80% confidence this spec is met.
US Smart Outlet Purchase Spec September 21, 2012
Doc: D10025-002 Tendril Confidential Page 5
3.3 Sub-metering Accuracy
The unit measures and reports Voltage, Current, Instantaneous Power, and Energy as described in
Section 2.1. Note that only Power and Energy are presently reported to TNOP. The accuracy is
specified as follows:
CurrentRMS VoltageRMS Instantaneous
Demand
Current Summation
Delivered
Low Normal
Range 0-1.7 ARMS 1.7-15 ARMS 100-150 VRMS 0.1 -3.0 kW [0, 281 TWhr)
Average
Accuracy + 50 mARMS + 3%
+ 2% + 4% or + 6 W Same as Inst
Demand in %
The current shunt sense accuracy is stated as 3% or 50mA, whichever is higher. Similarly, Instantaneous
Demand accuracy is either 4% or 6W, whichever is larger. Finally, the same % error determined for
Instantaneous Demand carries forward into Current Summation Delivered.
Distortion of the voltage or current can adversely affect the accuracies declared above. Typically this is
not an issue for line powered devices without an SCR or other switching components.
Tendril does not have the equipment or procedure to calibrate units.
3.4 Radio

channels are attenuated relative to other channels as follows:
Typical Tx Power
Level Power (dBm)
Channel 11 (2405 MHz) – Channel 23 (2465 MHz) 3 20
Channel 25 (2475 MHz) -3 14
Channel 26 (2480 MHz) -14 4
