NETIO PowerCable REST 101x is a smart WiFi power socket for integration with third-party systems using its open API (10 protocols). Use PowerCable REST to measure electricity consumption and switch its output on/off using one of the 10 Open API protocols, the web interface, NETIO Cloud, or the NETIO Mobile 2 app.

PowerCable is an industrial smart power extension cable with a WiFi connection to a LAN. Its web interface can be used to configure the device, display the energy metering values (V, A, kWh, W, Hz, TruePF) and turn on/off the controlled output power socket.

PowerCable REST 101x can be used for industrial applications. The product operates in a wide temperature range, supports FW upgrades over the web, can be controlled using a documented API, supports accurate energy metering, is capable of switching up to 16A when the current crosses the zero level, and more.

PowerCable REST 101x can be controlled with the NETIO Mobile 2 app. Use an Android or iOS device with the app to control the outputs of multiple NETIO products.

NETIO Cloud is a TLS-secured service for controlling the outputs from anywhere and monitoring the electricity measurement data.

Open API allows controlling the outputs over the network using various protocols (http XML/JSON, Modbus/TCP, MQTT, SNMP, Telnet and more... ).

AV drivers make it easy to connect NETIO sockets to professional Audio/Video systems such as Neets, CRESTRON, Control4 and more. 


Open API: Open interface

PowerCable REST 101x can be controlled with one out of 10 different M2M protocols:

The SNMP protocol can be always used in parallel to other APIs.

Regardless of the Open API used, PowerCable REST 101x can be always controlled from its web interface and from the NETIO Cloud service. The customer may use one Open API protocol and the NETIO Cloud service simultaneously.

NETIO PDUs have implemented HTTPs security.
The HTTPs is supported both for the WEB interface and for Open API protocols (JSON, XML). A customer certificate can be used.



The product can be connected to NETIO Cloud. Control hundreds of outputs from a single web screen. NETIO Cloud is an ideal solution for remote control and restarting. The NETIO Cloud service is a paid service.

  • All devices produced by the NETIO products company can be connected to NETIO Cloud.
  • Thanks to the included “Welcome credit”, the service can be used at no cost for the first 3 years.
  • Devices connected to the service can be controlled securely from anywhere over the Web (HTTPs).
  • NETIO Cloud can be used in parallel with another Open API protocol.
  • Communication with the Cloud service is secured (port 8883 - MQTTs - TLS)
  • NETIO Cloud uses a separate Open API (MQTTS protocol) to control all devices linked to a given user account. 

>> More about  NETIO Cloud 




Scheduler function

With the Scheduler (timer) function, each output can be individually switched on or off at specified times and days of week. The switching times are easily configured in a graphical interface.
  • Each output can have its own schedule
  • When a schedule is active, outputs can still be controlled with NETIO Cloud, the web interface and Open API
  • Scheduler functionality can be enabled/disabled (not edited) for each output from the NETIO Mobile 2 app.
  • Scheduler does not need an internet connection. However, a time source is needed – provided over the internet or, for example, by a local ADSL / WiFi router.
  • For special usage the Scheduler can be combined with PAB (Power Analyze Blocks):
    • Switching time is based on current sunrise/sunset based on your location
    • Whatever happend, defined output can be switched off on defined time (midnight for example).
    • Ask for more..

Wi-Fi connection

PowerCable REST connects to the network using WiFi (internal antenna). The initial WiFi connection is very simple: PowerCable works as a WiFi AP, searches for available WiFi networks and asks the user to select from them. A web wizard guides through the connection process. No mobile app is needed to install the device.

The NETIO WiFi Reconnect feature ensures stable availability of the device in an ordinary WiFi network. WiFi Reconnect ensures a stable LAN connection even in cases of an unstable WiFi AP, a necessity to switch over from one WiFi AP to another due to fluctuating signal strength, and so on.


AP (Access Point) installation mode

Wi-Fi connection setup (AP mode)

The package includes the PowerCable QIG with instructions on how to quickly connect the device to your WiFi network and perform initial configuration over the web interface.

  • NETIO PowerCable creates a WiFi network that you connect to with your PC or mobile phone.
  • The device then scans for WiFi networks in the vicinity, and lets you choose from a list and type the password.
  • NETIO PowerCable then confirms the connection to the network and displays the assigned IP address.
  • NETIO PowerCable devices can be discovered in the LAN using the NETIO Discover tool.


NFC preconfig for easy and quick configuration of NETIO smart power strips

NFC pre-config – Installation in 60 seconds

WiFi connection (SSID and password) can be configured without turning PowerCable on. Set the configuration using the app (NETIO Mobile 2) and transfer it to PowerCable from your phone or tablet over NFC. This technology significantly reduces the installation time when installing many devices.

The entire process including unpacking takes at most 60 seconds; after that, your smart WiFi socket is connected to the LAN.

ZCS (Zero Current Switching)

An important feature of NETIO PowerCable REST 101x is ZCS (Zero Current Switching). ZCS means that the internal relay switches the output power outlet on or off when the current crosses the zero level.

  • Thanks to ZCS, the device can control switching power supplies (servers, computers and other IT equipment) up to the maximum rated power.
  • Using ZCS (Zero Current Switching) to switch the outputs reduces the chance of a circuit breaker tripping when power is restored after an outage.
  • Since the relay switches when the sinusoidal current curve crosses the zero level, negative effects of inrush current are significantly reduced.
  • ZCS significantly reduces EMC interference generated by switching a 230V output on and off.
  • ZCS extends the lifetime of connected equipment; especially in case of frequent on/off switching of devices that are not designed for that (such as switching power supplies).

>> Glossary: ZCS


User can define output state after power restoring - PowerUp state

PowerUp state

For some applications, it is important to set the power socket state immediately after the device is powered on (or the power is restored after a failure). With some machines it is important to avoid momentary switch-on or switch-off. This parameter therefore defines the behavior of the 110/230V output power socket before the standard communication with a master system starts to work.

  • On
  • Off
  • LAST state restores the last state before the power was disconnected

Delayed switch-on function ensures that the 110/230V power output is switched on with a configurable delay (several seconds) after the power is restored. This can avoid circuit breaker tripping when power is restored after an outage.

>> Glossary: PowerUp state



WatchDog Ping + Power

PowerCable REST 101x is equipped with WatchDog PING (IP WatchDog) and WatchDog Power consumption (PAB).

  • WatchDog Ping continuously monitors whether a given process or a part of a system work as they should. If not, the WatchDog restarts the process.
  • WatchDog Power is "Condition" & "Action" (PAB - Power Analysis Block & Rules) based autonomous system. It continuously monitors current (energy) of monitored device powered from any metered power output of NETIO PDU device.

Is it possible to change the on/off state with the button on the power extension cable?

Yes. Press the button 3 times, e.g. with a straightened paper clip, and the output switches to the other state.

Is it possible to specify in which state the output (metered power socket) will be after power-up?

When the device is powered up, the output is set according to the PowerUp Init setting (On / Off / LAST value).

How can I add an icon to the Windows desktop to switch off/switch on/toggle the outlet?

Create a shortcut, select an icon and assign a command to invoke cURL with parameters to access the correct URL (see URL API).  The AN19 example shows how to control the output (electrical socket) by accessing a particular URL. Use the example that invokes cURL and assign this invocation to the icon on the desktop.

I forgot the password, or WiFi is inaccessible, how can I reset the device to factory defaults?

For the correct procedure, see the PowerCable xxx QIG (Quick Installation Guide).
It is available for download at this page as well as included in the product package.

To restore factory defaults, hold the button pressed, plug the device into a mains outlet and keep holding the button for at least 10 seconds (Green LED quickly flashing for 1sec). The device reverts to factory settings and the AP mode is activated (Yellow LED blinks quickly).


My WiFi stopped working. I want to connect PowerCable REST 101x to a different WiFi network but I do not want to restore all settings to factory defaults.

This is possible. Leave the device powered on and hold the button for 15 seconds until the LED flashes (yellow). The device will re-enter the installation AP mode, where you can connect to its WiFi AP and select another available network from the list.

Is it possible to control the PowerCable REST 101x output using a mobile app?

Yes, the NETIO Mobile2 app is available. For details, see NETIO Mobile2.

Thanks to the open API, third-party mobile apps can be used, too. We are preparing AN38 and AN39.


Can PowerCable REST switch on the output at a specified time?

Yes, update the firmware to version 3.0.0 or higher (Scheduler function).
Periodic switching can be also programmed in a master system that controls the output as needed via the Open API.

When using the WiFi power cable as an electrical cable with kWh meter, how do I get the measured values?

All values measured by PowerCable REST are displayed in the device’s web interface and accessible over Open API.


Is it possible to use the WiFi smart plug as a remotely-controlled smart power outlet?

Yes, this is one of the main applications of PowerCable REST 101x. The output power socket can be switched on or off for instance by invoking a cURL command with appropriate parameters (see AN19).

Are any OEM modifications of the product possible?

Yes. We offer the “NETIO COBRA DevKit” product for deliveries of custom versions. 

For more information about OEM use, please contact us.
