NETIO 4All Smart socket

NETIO 4All Smart socket

NETIO 4All smart sockets with WiFi / LAN are in a robust metal housing.  NETIO 4All features an electronic fuse as well as overvoltage and surge protection.


NETIO 4All electrical sockets include energy consumption metering functions. Each of the 4 sockets measures the current [A] and consumption [kWh].


Functions for ordinary IT users

  • Sockets can be controlled over the Web or with a mobile app (iOS / Android).
  • The switching of sockets can be time-controlled by the Scheduler with a graphical interface.
  • The IP WatchDog (automatic restart) function controls the 230V socket by detecting “ping” responses. It can be used to restart unresponsive servers, routers or microwave links.
  • ANxx (Application Notes) is a library of examples of using NETIO electrical sockets in various applications, connecting to third-party software, and so on.



As a unique advantage, individual electrical sockets of NETIO 4All smart socket devices can be controlled with a wide range of supported network protocols. These network protocols are called the M2M (Machine to Machine) API (Application Programming Interface).

  • Telnet (Kshell) / ssl
  • SNMP / SNMPv3
  • XML (http / HTTPs)
  • JSON
  • SIP
  • MQTT (MS Azure)



NETIO 4All smart sockets support a high level of network security. The HTTPs protocol establishes a secure connection between the browser and the web server.

The third SNMP v3 generation offers higher security in comparison to previous SNMP versions. The MQTT protocol for IoT cloud applications includes SSL security. 

LAN / WiFi connectivity

NETIO 4All can be connected to a LAN via Ethernet (RJ45) or WiFi. NETIO 4All can also work as a WiFi AP (Access Point) to connect to a LAN via WiFi.

An advantage of NETIO 4All over NETIO 4 is an external WiFi antenna with a RSMA connector and a higher sensitivity (-3dBi). Thanks to the RSMA connector, the supplied “pigtail” antenna can be replaced with an external antenna to provide a better WiFi coverage.



NETIO 4All for various electrical sockets

NETIO 4All smart electrical sockets are available in several versions. The smart sockets (or PDU – Power Distribution Unit) differ by the mechanical type of the electrical socket, as indicated in the model name: 

  • NETIO 4 DE version = type F sockets – Schuko (DE, IT, ES, NL, SE, FI and other countries)
  • NETIO 4 FR version = type E sockets (FR, CZ, SK, PL)




Can NETIO 4x switch an output on or off at a specified time?

Yes. Switching sockets on and off at given times can be configured using the “Scheduler” function and its graphical interface.

Another option is to write a Lua script. Such a script can also communicate over the Ethernet and makes some tasks easier to set up. 


Is it possible to control NETIO using an IoT cloud?

Yes, NETIO 4x products (4/4All/4C) support MQTT (MS Azure) for connecting to IoT (Internet of Things) applications in a cloud.


Is it possible to control NETIO 4x outputs with a mobile app?

Yes, use the NETIO Mobile app. The mobile phone and all controlled devices must be in the same network. The app supports NETIO 4/4C/4All and can control multiple devices.


Is NETIO 4All a smart PDU or a smart socket device?

The terminology is not settled; however, in general a PDU refers to a device intended for a 19" rack. Therefore, a PDU often means devices with IEC320 outlets. On the other hand, devices with 230V wall-like outlets are usually called “smart sockets” or a “smart power strip”.
