• Wireless & Retrofit
• Measures Single Phase Power Vrms, Irms, Active Power, Apparant Power, PF and Line Frequency
• Can Trigger Safety Alert
• Cloud Connected with In-App Visualisation and Analytics
• Easy Setup
• Works with Android & iOS User Applications

• The Energy Measurement Sensor Core includes Active, Reactive, Apparent Energy calculations, as well as voltage and current rms measurements.
• This information is ready to use for energy billing by using built-in energy scalars.
• Many power line supervisory features like SAG, Peak, Zero-crossing are also included in the energy measurement core.
• Less than 0.1% error on active energy over a dynamic range of 1000 to 1 @ 25℃
• Less than 0.5% error on reactive energy over a dynamic range of 1000 to 1 @ 25℃
• Less than 0.5% error on rms measurements over a dynamic range of 1000 to 1 for current and 100:1 for voltage @ 25℃
• The Power sensor data is communicated over Zigbee to the NUOS Zigbee Gateway and the appropriate actions based on the Safety Mode (triggering safety alert SMS & In-app Notification) are triggered by the Gateway if the mode is enabled.
• Has in-built Zigbee and acts also as a repeater for Zigbee Mesh Network.
• Can be accessed in dual mode – local only through the same WiFi network as well as through cloud from anywhere in the world for seamless connectivity using Android and iOS Application.
• Supports ease Safety Mode Enable/Disable from mobile application.
• Support IFTTT for taking action based on certain triggers
• Supports change of settings through cloud from anywhere in the world.

• • Please check NUOS Zigbee Gateway configuration for setting up and configuring the gateway.
  • Push the NUOS Sensor inside the switch plate till it snap fits.
  • Connect the Red Wire from behind the sensor to the Line/Live wire of the electrical circuit.

• Connect the Black Wire from behind the sensor to the Neutral wire of the electrical circuit.
• Plug in the blue colored Current Clamp with back wire DC Jack into the rear of the sensor housing.
• Connect the clamp on the Neutral or Live of the circuit for which the power needs to be measured.
• Make sure the wiring connections are tightly secured by insulation/electrical tape to above lose connections and arcing behind switchboard.
• Close the switch board once the wiring is completed.
• New switches and sensors automatically associate with the gateway on power-up and can be added in the desired room using the user application.
• Please refer to the installation manual for detailed process with images.
