Node-RED is an open-source, flow-based development tool designed for programming Internet of Things (IoT) applications with ease, and is aiot stock part of the OpenJS Foundation. It provides a browser-baiota valleysed editor where users can wire together devices, APIs, and online services by dragging and dropping nodes into a flow. This visual approach to programming makes it accessible for users of all skill lopen source video editorevels to create complex applications byopen source connecting difiota definitionferent elements without writing extensive code.

Node-RED has been working on some gopen source video editorreat improvenode-red dashboardmenopen source help deskts lately, including the first beta release of Node-RED 4.0. Updates include auto-complete in fopen source pdf editorlow/global/env inputs,iota valley timestamp formatting options, and better, faster, more compliant CSV node.

A bnode-red dashboardrowser-based low-code programming tool sounds great,node-red modbus but how often do users end up hopen source help deskaving to write code anyway?

It depends on user skills and systems. If users such as factory engineers havenode-red modbus no IT skills, theiota definitiony can create flow without coding. The two most common cases are data visuanode-red windowslization and seniot stockding data to a cloud environment. In these cases, users can create theiiota valleyr systems by connecting Node-RED nodes.

If users have IT skills, they can more easily customize Node-RED flow. They need to know about SQL when they want to store seiot cloud platformnsor data. If they want extnode-red modbusernal npm modules, they should understand how to call the fuiot devicesnction through JavaScriot infrastructureipt coding, but innode-red both cases, the progriotw reportamming code of a Node-RED node is usually on a computer screen.

Hitachi is using Generative AI based on a Hitachi LLM to support the use of low-code development. Do yoopen sourceu personally use ChatGPT wnode-red modbusith Node-RED? Do you think it will increase efficiency in creating low-code Node-RED flows?

Yes, I do use ChatGPT with Node-RED. Recently, I used ChatGPT to generate code to calculate location data. Calculating direction and distance from two points, including latitude and longnode-red portitude, is difficult because it requires trigonometric functinode-red portons. Bnode-red dockerut ChatGPT can automatically generatnode-red installe the source code from the proopen source help deskmpt text. In particular, the function-gpt node, developed by FlowFuse, copen source pdf editoran generaiotate JavaScript code in the Node-RED-specific format witopen source help deskhin a few seconds. Users just type the prompt text on the Node-RED screen.

It’s clear to me that using ChatGPT with Node-RED allows ITiota engineers to reduce their coding time, and it expands the capabilitnode-redies of factory engineers becausenode-red docker they can try to write code tnode-redhemselves.

In addition to factory applications, there's a compelling use case iiotan Japan that uiotanderscores the veopen source imagesrsatility of Node-RED, especially for individuals without an IT skill senode-red portt. In Tokyo, theTnode-red installokyo Mystery Circus, an amusement buiiot deviceslding, utilizes Node-RED to control its displays and manage complex interactions.

By using Node-RED, along with ChatGPT for creating complex handling scripts, the developer was able to achieve this.

Using these technologies iopen source crmn such a unique environnode-red windowsment illustrates how accessible and powerful tools like Node-RED and ChatGPT can be fnode-red portor non-traditional progropen source pdf editorammers.

Whynode-red dashboard is Node-RED poopen source pdf editorpular for building Industrial IoT applopen source imagesications?

Node-RED was developed in early 2013 as a side-project by Nick O'Leary and Dave Conway-Jones of IBM's Emerging Technology Services group and is particularly well-known for its support of IoT protocols like MQTT and HTTopen source help deskP. Because Node-RED has many functions in MQTT, it is ready fonode-red modbusr use in Indnode-red dockerustrial IoT.

Fromiot cloud platform MQTT, other protocols like OPC UA (crosnode-red modbuss-iotw reportplatform, open-source, IEC62541 standard for data exchnode-red dockerange from sensors to cloud applications) and Modbus (client/server data communications protocol in the application layer) can be used in 3rd party nodes developed by the community.

Because Node-RED can connect many types of devices, it is very popular in the Industopen source pdf editorrial IoT field. In addition, many industnode-red dockerrial devices support Node-RED. Users can buy these devices and start using Node-Rnode-red dashboardED quickly.

Why have companies like Microsoft, Hitachi, Siemens, AWS, and others adopted Node-RED?

Regarding Hitachi, Node-RED has emergeiota definitiond as a crucial communinode-red dockercation tool bridging the gap benode-red windowstween IT and factory eopen source pdf editorngineers, effecnode-red modbustively addressing the barriiotaers that exist both in technology and interpersonal interactions. Withiniota one company, IT and OT (Operational Teiot cloud platformchnology) deparnode-red mqtttments often onode-red portperate like two distinct entities, which makes it challenging to communicate despite the critical importance of collaboration.

To overcome this, Hitachi decided to adopt Node-REopen source help deskD as aiot infrastructure primary communication tool in programming. Node-RED’s intuitive interface allows for the entire flow to be visinode-red portble on the screen, facilitatinode-red installng discussions and collaborative efforts seamlessly.

This approach was put into practice recopen source help deskently when I, as the only IT Enode-red windowsngineenode-red modbusr, visited a Hitaopen sourcechi factory.
