Node-RED example of Modbus/TCP communication with NETIO 4x / PowerCable
14.6.2019

NETIO AN32 demonstrates how to control outputs and read measurements (kWh, A, V) from the 110/230V smart sockets from a Node-RED application using the Modbus/TCP protocol.
Node-RED is a programming tool for wiring together hardware devices, APIs and online services. Modbus/TCP is an industry-standard protocol. The Application Note applies to NETIO 4x devices as well as PowerCable Modbus 101x power sockets with WiFi.

 

Node-RED example of REST XML communication with NETIO 4x
2.4.2019

Node-RED is a programming tool for wiring together hardware devices, APIs and online services. The AN31 Application Note shows how to control NETIO 110/230V smart sockets from Node-RED using HTTP - REST XML.

 

 

Node-RED example of REST JSON communication with NETIO 4x
2.5.2019

The AN30 Application Note demonstrates how to read consumption data from NETIO 4x and PowerCable REST smart socket devices and how to control their outputs using REST API – JSON. The netio.json file is transferred over http. Node-RED is a programming tool for wiring together hardware devices, APIs and online services. It can run, for example, in a cloud, on a local PC, or in a Raspberry Pi.

 

Node-RED example of URL API communication with NETIO 4x
12.3.2019

Node-RED is a programming tool for wiring together hardware devices, APIs and online services. The AN29 Application Note shows how to control 110/230V smart sockets from Node-RED using URL API. Invoking an URL is a simple but only a one-way solution (it is possible to control NETIO 4x outputs from Node-RED but it is not possible to measure consumption).

AN27 ModbusTCP with NETIO 4x – Control and measure LAN power sockets
3.10.2018

The AN27 Application Note demonstrates how to control NETIO 4x smart sockets and PowerCable Modbus devices using the Modbus/TCP protocol. Modbus/TCP is the de-facto industry standard for connecting sensors and devices to PLCs, SCADA systems and smart home systems. NETIO products can be controlled over Modbus/TCP as 1-bit outputs (“coils”). In addition, values can be measured and advanced control is possible using registers.

 

 IP WatchDog 2 from 10 – list of monitored devices, failure indication by power output (Lua script)
22.2.2019

Do you need an indication that any out of 10 LAN devices is not working or unavailable? Regardless of whether a cable got loose, WiFi was disconnected or the UPS failed, when one or more of the ten devices fail to respond to PING, the Lua script described in this Application Note lights up a red warning light.

 

 JSONHTTP(S) protocol to control NETIO 110/230V power sockets (3x REST API)
3.5.2019

The AN21 Application Note shows how to access measurements and control electrical sockets on a NETIO 4x device from third-party applications using the JSON protocol. AN21 demonstrates several different ways to control NETIO power sockets by transferring a netio.json file over http. The first method uses the “Device HTTP(s) File Upload” tool in the device’s web interface. The second method transfers the JSON file using a Chrome browser extension. The third method uses CURL (command-line tool) to transfer files over http.

 

 

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.

 

 

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.
