AN20: XML HTTP(s) protocol to control NETIO smart power sockets 110/230V
8.10.2018

The AN20 Application Note demonstrates how to control NETIO 4x smart sockets using the XML protocol. The XML protocol transfers a text file with a xml structure over http(s). NETIO devices contain built-in tools to easily test the protocol by the user.  The XML protocol is supported by all NETIO 4x devices (NETIO 4 / 4All / 4C).

M2M API (http GET) protocol to control NETIO power sockets/outlets
18.12.2017

The AN19 Application Note demonstrates the use of the “URL API” or “http get” M2M API protocol. By invoking a certain URL, one of  electrical outputs 110/230V can be switched On / Off / Toggle / Short pulse. This protocol is supported by all NETIO 4x devices (NETIO 4 / 4All / 4C).

 

AN18 Lua access to RS-232 serial port
13.8.2018

The AN18 Application Note contains a Lua script that controls the RS-232 serial port and the sockets. The result is the ability to switch individual electrical outputs on or off over RS-232 using a text-based protocol that is the same as the Telnet M2M protocol.   

AN18 demonstrates the control of the RS-232 serial port (with a request-response protocol) using a Lua script. The commands to control the power outputs can be modified (in the Lua script) to change the serial port protocol.

 

 

AN15 One switch to turn off 20 power outputs (monitors) over LAN
11.3.2020

The AN06 example shows how to quickly turn on or off dozens of electrical power outputs (sockets) over LAN by flipping a single central switch. The central switch is connected to the serial port (PowerPDU 4C). The URL API protocol is used for control.

 

AN14 Reading the digital inputs of a STE2 device
8.12.2017

The NETIO AN14 Application Note shows how to connect NETIO 4x smart sockets and the STE2 online wifi thermometer by HW group. This Lua script turns individual sockets at the NETIO device on or off according to the states of STE2 digital inputs. The devices communicate over a LAN; values are transferred in a .xml file. The script can be modified for other devices and xml data. 

STE2 thermometer (HW group) switches NETIO sockets based on temperature
23.10.2017

STE2 by HW group is a LAN/WiFi thermometer/humidity meter. The NETIO AN13 Application Note presents a Lua script that connects NETIO 4x smart sockets with the STE2 thermometer. 230V electrical sockets are switched on or off according to the temperature (or humidity) measured by STE2. The devices communicate over a LAN, values are transferred in a .xml file. The script can be modified for other devices and xml data

AN12 MQTT control of NETIO smart sockets using the HiveMQ broker
6.8.2018

NETIO 4x power sockets (4x 230V, LAN and WiFi) can be controlled over the Web and with various M2M protocols. Supported protocols include MQTT. Application Note AN12 describes the use of the MQTT protocol in the “Generic” mode with the HiveMQ public MQTT broker. This public broker is intended for testing; for live use, we recommend to use your own installation of this or another MQTT broker.

 

SNMP management of 110/230V power outlets from the command line in Windows and Linux
19.2.2018

NETIO 4x electrical sockets (PDU) can be monitored and controlled over LAN/WiFi using SNMP. In this way, it is possible to measure the immediate consumption (NETIO 4All only) or to switch individual 110/230V sockets on or off. This AN11 Application Note shows how to perform SNMP v3 read and write operations in MS Windows or Linux. 

AN10 Telnet control of electrical power sockets (M2M API – KSHELL)
16.10.2017

NETIO 4x electrical sockets (NETIO 4 / 4All / 4C) can be controlled over a LAN using the Telnet M2M API protocol and KSHELL commands. The NETIO AN10 Application Note demonstrates how to use Telnet to control individual sockets, gives a brief description of the KSHELL protocol and shows examples how to test the communication in Windows using several utilities. 

Lua script that detects a connection to the Internet and automatically restarts, for example, a microwave connection
23.10.2018

AN09 demonstrates a Lua script that detects a dropped Internet connection and automatically restarts e.g. a microwave link. The script periodically sends PING (icmp) requests to the 1 or 2 configured IP addresses. When none of these two addresses respond for e.g. 60 seconds, one of the 230V sockets is turned off for 20 seconds (short off – restart).

Cyclic traffic lights in Lua according to a defined table
20.11.2017

AN08 demonstrates the use of a Lua script to switch 230V sockets on/off according to a table. The example table contains 8 states. Each state has a defined duration (1s minimum). This example can be used as cyclic “traffic lights”

AN07 Periodical scheduler for many actions based on text file - Lua script
28.1.2019

The AN07 Application Note shows a Lua script that turns individual 110/230VAC sockets on and off at specific times according to a predefined schedule. The state table can contain dozens of rows with actions to be performed at specified hours or days of week.

 

NETIO AN06 Daily report by e-mail (Lua)
14.1.2020

AN06 is a pair of Lua scripts that send, once per day, an e-mail report showing how many times was each output switched, and how much energy the respective appliance consumed in terms of kWh and price (€ / $ / CZK ...). Receive a report every day about the electricity consumed in a day and in a week at each output (electrical socket). 

PowerUp email alert (Lua)
19.12.2019

AN05 is a simple Lua script that sends an e-mail every time the NETIO device is restarted. This Application Note AN05 shows how to send e-mail using Lua.

Remote power socket control by URL (http GET handled in Lua script)
3.4.2018

The NETIO 4 smart sockets device is connected to a LAN or a WiFi network. Individual sockets can be easily switched on and off by accessing a URL in a browser or from the command line. This control method is very easy to use. This NETIO AN04 describes a Lua script that reacts to parameters contained in the http get request (URL). Unlike the standard M2M API based on http GET, the custom Lua script can make the sockets react to parameters with custom names.
