Building the tool I wish existed – SCADA-System in Node-RED

Hi everyone,

I work as a refrigeration technician in Sweden, and for the last 3 to 4 months I’ve been building my own SCADA-style system with Node-RED.

The reason is simple: most existing products are far too expensive, and a lot of the hardware and software out there is honestly not very good. A big part of the problem is that there is very little real competition in this space.

I wanted to see what could be built from a field technician’s perspective instead. Something more practical, flexible, and easier to use when working with refrigeration systems and Modbus devices.

So far I’ve built things like system overview pages, controller detail cards, auto-discovery, profile-building tools, and some engineering-focused utilities.

It’s still a work in progress, but I thought it could be interesting to share here since Node-RED is a big part of the project.
The video may seem like a big tech company but it is just me in my garage usin AI…

Welcome to the forum. It looks good.

Are you planning on open sourcing this or are you hoping to sell it?

Which dashboard are you using?

The idea actually came from frustration with existing systems in refrigeration and industrial control. Many solutions are very expensive and still quite limited or difficult to work with, so I started experimenting with building something simpler and more flexible myself.

Right now it's still an early project and I'm mainly building it to solve real problems I see in the field. Long term it might become a product, but I also like the open community around Node-RED, so I could imagine open-sourcing some parts of it (for example flows, tools or integrations).

Still figuring out the direction and Im using dashboard 2
