Switching a 110/230V socket on or off simply by accessing a URL is very simple to implement. Also called “CGI”, this control method used to require a custom Lua script.

Starting from firmware version 3.x.x, NETIO 4x (NETIO 4 / 4All / 4C) supports this control method as a standard M2M API protocol. No more Lua scripts, everything works with just a few clicks.

In addition, the communication can be secured with a password, and commands to toggle or power-cycle the sockets are supported.


Our online demo offers access to all three device types in various configurations so that you can try them out as if they were already on your desk.


NETIO 4All smart sockets support electricity metering. Starting from FW 3.0.1, NETIO 4All can meter electricity consumption. Measured values are accessible using all M2M API protocols.

New firmware 3.0.1. allow to control smart power sockets via XML, JSON, URL api protocols

What's new in NETIO 4x firmware 3.0.1

  • New M2M API protocol – XML / HTTP(s)
  • New M2M API protocol – JSON / HTTP(s)
  • New M2M API protocol – CGI (URL address - HTTP post) – no Lua script required any more
  • TCP connection port can be modified per M2M API protocol. HTTP(s) based communication share 2 ports only

and more

Firmware version 3.0.0 boots 28 seconds faster than the previous version

Ideally, our smart sockets should start working immediately after being switched on. We are working on making that happen.

Firmware version 3.0.0 boots 28 seconds faster than the previous version. We are working on reducing the boot-up time even further. 


MQTT (Message Queuing Telemetry Transport) is a protocol designed in 1999 for sending short messages. Thanks to the IoT boom, it has become one of the most frequently used connection standards.

NETIO 4x (NETIO 4 / 4All / 4C) devices now support MQTT in a version suitable for MS Azure. A simplified “MQTT generic” implementation is coming soon
