The Internet of Things brings many opportunities in the field of smart home and business automation. Linking up, what were once separate systems into a single management console requires the use of industry wide protocols and interfaces. All of these systems require electrical power and with that comes the need to be able to monitor power and energy usage and control the power outlets and sockets that supply them.
The Internet of Things (IoT) was bound to happen. Provide a way to connect billions of remote devices and allow them to share data easily and accurately, and the rest will follow. Most organisations are now dependent on some aspect of the IoT or Industrial Internet of Things (IIoT), and will be processing data within their core IT server rooms, one or more Cloud datacentres and in Edge computing applications.
NETIO smart power management devices provide a cost-effective way to meter energy usage and provide remote control to individual power outlets and sockets. The new NETIO Cloud provides these features over a secure internet-based connection using an internet browser and will help organisations to improve how they manage remote installations whilst reducing field service engineering costs.
Lua is a basic programming language designed for use in embedded applications. It is a cross-platform language as the interpreter is compiled bytecode written in ANSI C and has a relatively simple C API. Lua is used for user scripts and supports a limited set of variables including Boolean values (true/false), numbers, strings and tables. In a compatible smart power device, a Lua script can be used to control power outlets and IP/LAN connectivity. A Lua script can run continuously or when trigged by an event to power sockets ON/OFF, send emails, receive and send ‘ping’ messages, download and parse XML/JSON files over http.
A URLAPI is a simple method for passing parameters as a part of a URL address starting with http or https. The address command can be entered into the address bar of a web browser including Google Chrome, FireFox, Apple Safari or Microsoft Internet Explorer or Edge.
Zero Current Switching (ZCS) ensures that a relay contact is closed at the zero crossing and opened at the precise moment when zero current flows through it. This has a number of advantages for smart power devices using relay switching techniques. With less potential harm from inrush currents, there is less wear on the relay itself and greater protection for connected switch mode power supplies (SMPS). There is also significantly reduced electromagnetic interference from repeated switching On/Off. Opening a relay contact when the current is zero is important for inductive loads (motors, transformers) but less so for capacitive loads including switch mode power supplies (SMPS) of the type found in computers, servers and IT network peripherals.
