We are excited to announce HELIO 26.1.1, our first feature release of 2026. This release brings significant data visualization upgrades — a new 2D Plot element and a redesigned Gauge & Radial Bars — alongside Vendor Users and the first public preview of the HELIO HTTP API.

Download HELIO​

Highlights​

Data Visualization: 2D Plot – Visualize the Relationship Between Two Datasets​

The new 2D Plot element visualizes the relationship between two datasets by plotting one array against another on a two-dimensional chart. Each axis can be connected to a live array variable from the PLC — perfect for real-time sensor profiles, quality curves, and calibration data.

Not everything needs to be live. Each axis also supports static data sources: use the brand new Dynamic Property called Sequence to generate an evenly spaced range for either axis.

Gauge & Radial Bars – Sharper, More Configurable, and Design System-Ready​

The Gauge and Radial Bars elements have received a major set of improvements in 26.1. Responsive behavior inconsistencies have been resolved, making both elements even more reliable across different screen sizes and layouts.

←→

On the configuration side, you can now apply a manual status to override the automatically calculated one — useful when process logic needs to force a warning or critical state regardless of the measured value.

The new Ticks sections gives you fine grained control over tick display:

Finally, both elements are now tightly integrated with the HELIO Design System and its theming capabilities – allowing our designers to tailor every visual detail even more easily to your brand.

Vendor Users​

Machine vendors can now embed dedicated service accounts directly into a HELIO project. Vendor Users & Roles never appear in the HMI's user management — customer administrators simply cannot see or modify them, giving your service team a reliable entry point on every deployed machine.

Project Import – Drag, Drop, Done​

Importing a project into the HELIO IDE has never been easier. Simply drag and drop a .helio file anywhere onto the Home Page — it appears highlighted in your project list, ready to open.

Early Access: The HELIO HTTP API – Built to Extend​

The complexity of modern HMIs constantly challenges us to view extensibility as a fundamental building block. Until now, developing and operating HMIs with HELIO required manual engineering via the HELIO IDE. With the new HELIO HTTP API, we are opening HELIO up to the world beyond the manual user interface. Scripts, applications, and AI agents can now communicate directly with HELIO, opening up workflows that go beyond what the user interface alone can do.

The HELIO SDK lets you extend HELIO from within a project. The new HTTP API lets you safely reach into HELIO from the outside — from any tool, any language, or system.

We are confident that this reliable API will make HELIO even more useful for product teams by enabling extensibility and automation. Just like the HELIO SDK, we designed it so that you can extend HELIO with confidence.

For example, it follows the OpenAPI specification, making it self-explanatory and easy to access from any language or stack. This clear and structured system boundary between HELIO and other systems allows you to build sustainable, long-lasting integrations and tools on top of it.

First Stop: User Management API

The first capability of the API in this early-access version is HMI user management. For example, machine builders can empower their customers to flexibly manage user roles and access rights by creating import scripts for custom, customer-specific access management file formats.

As an early access feature, the API is actively taking shape — we're refining it based on real-world usage, meaning that breaking changes in this phase are expected. As with the SDK, we are developing this feature in close collaboration with our customers, to lay a solid foundation for the years to come.

We are excited to announce that HELIO 25.4.0, our fourth and last feature release of 2025, is now officially available to everyone. This release lets you extend HELIO with confidence with the public release of the new HELIO SDK.

Download HELIO​

Highlights​

The HELIO SDK – Extend With Confidence​

This has been our most requested feature for a while, and we are excited about how it turned out. With the HELIO SDK you can now extend the core functionality and create new controls, widgets or entire page types that integrate fully with our easy-to-use editor and responsive renderer.

Use the HELIO Design System for the common ground, and add custom components for what makes your machine unique.

Here's just one example: a Circular Flow element which was built entirely with the SDK. Each section is a custom element you can configure, add click actions to, and mark as completed or active.

Perfect for guiding operators through multi-step processes or maintenance workflows – and it integrated seamlessly with HELIO's existing building blocks such as Actions and Dynamic Properties.

IDE Refresh – Creating Room to Grow​

After extensive conversations with our customers and comprehensive UX testing with real users, we've given the HELIO IDE a major refresh. But this isn't about making things look pretty – it's about removing friction from your daily work.

The IDE works better today and is ready to evolve with your needs for years to come.

A Refreshed Home Page

We've aligned the Home Page of the IDE with the layout of Project Editor giving you a more consistent behavior.

←→

• You can now quickly switch between Projects, Translations, IDE Users.
• Documentation, support, and getting-started resources are no longer buried. They're right there in the Home Page sidebar, with the prominence they deserve.

A Refreshed Project Editor

The Project Editor has been tuned for clarity, efficiency and growth.

←→

We've introduced a new sidebar to switch between the editor's views. In contrast to the previous tab navigation, it can grow sustainably as we add new capabilities – without cluttering your workspace.

Many quality of life improvements have been made, e.g. we changed the Test-Mode from a Button-Bar to a simple Switch. Toggling the mode is now much easier since it requires no mouse movement at all!

Meet the New HELIO IDE Menu

We love this one because it solves challenges we saw in our usability tests. Especially new customers were having a hard time navigating the IDE. That's why we introduced the HELIO IDE Menu with a clear button design to make the most important navigational features easier to access.

Rulers for Live Trends - Pause and Inspect​

This is another long awaited feature from the HELIO community: the Trend element is now able to be analyzed. Tap any trend line to pause the data and bring up an interactive ruler that reveals exact values at that moment in time.

Visualizing more than one trend? The ruler automatically aligns across all visible trends, letting you compare values and spot correlations instantly.

Sankey Diagrams - Make Every Flow Visible, Every Loss Obvious​

Understanding where energy goes or how production flows through your facility shouldn't require mental gymnastics. Sankey diagrams transform complex flow data into intuitive visual representations where the width of each path shows you exactly how much is moving - and where. The new Sankey Diagram Page and Sankey Diagram let you build powerful flow visualizations directly into your HMI.

←→

Map energy distribution across your machine or facility, track material flows through production lines, or visualize any process where understanding proportional flow matters. Give operators and engineers the clarity they need to optimize processes and reduce waste.

Personalization v1 – HMIs That Adapt to People​

Industrial environments are as diverse as the people who work in them. Operators bring different experiences, preferences, and needs to their daily work. HMIs are expanding to new contexts too – from small tablets on the factory floor to large TV screens monitoring entire production lines. In the past, everyone got the same interface and experience. Same text sizes. Same contrast. Same colors. One size fits nobody.

←→

We're changing that with Personalization – a new system that lets HMIs adapt to each operator's needs. This isn't just about convenience. It's about accessibility, efficiency, and creating interfaces that work for everyone.

HELIO 25.4.0 introduces a dedicated Personalization dialog where operators can adjust their settings. And we've made integration simple: a new built-in Personalization Header Cell launches the dialog with a single click. Add it to your HMI header, and operators have instant access to their personalization options – no custom actions or navigation needed.

Starting With Zoom: This first version launches with Zoom to take control of text sizing. Operators can adjust the zoom across the HMI to match their readability preferences – whether they need larger text or want to fit more information on screen. Settings persist across sessions and devices, so configure once and you're done.

What's Next? This is just the foundation – we're planning more accessibility and personalization features that will all be available in the same dialog. These include a high-contrast mode for operators working in bright environments or with visual impairments.

This is a long-term investment in making HMIs work better for everyone. As always, we're listening – if there are specific accessibility or personalization features your operators need, let us know.

We are excited to announce that HELIO 25.3.1, our third feature release of 2025, is now officially available to everyone. With HELIO 25.3.1, you can connect faster, run stronger, and build better.

Download HELIO​

Highlights​

Let's dive into the highlights of this release…

OPC UA: Connect Faster. Run Stronger. Build Better.​

HELIO's connection startup just got a major upgrade. Whether you're developing in the IDE, commissioning projects, or running in production, HELIO now connects to OPC UA servers instantly. This improvement comes from listening to our customers and a dedicated team effort across engineering and design.

Your connections will be rock solid now, whether you’re working with controllers with limited resources or with large data trees – even when PLCs disconnect and reconnect. Less waiting. More building. Better results.

IDE: Performance Improvement for Large Translation Sets​

We've reworked our translation engine to improve support for projects with large sets of translations. HELIO is now handling translation sets of 50,000 entries with ease. It still provides instant keyboard feedback and adjusts translations in the blink of an eye.

Last Active Message Metadata – Critical Information at a Glance​

←→

Industrial operators need instant visibility into system status, especially when messages demand attention. While HELIO has always let you display active message counts, operators often need more context.

The new Last Active Message Metadata dynamic property type delivers exactly this information. Operators can now see the complete details of the most recent message directly in their HMI header or status displays.

This follows a proven pattern in industrial interfaces: giving operators immediate context about the most critical or recent system events without requiring them to navigate away from their current task.

Fixed Size Overlays – Precision Control When You Need It​

Sometimes you need dimensional precision with your overlays. Picture this: an interactive SVG where operators click on a layer and need just a small, focused overlay showing a brief status update or instruction. You don't want a sprawling, responsive overlay that dominates the screen – you want exactly the right size, exactly where you need it. The Open Page as Overlay action now supports fixed sizing, letting you specify exact width and height dimensions for your overlays. Perfect for those compact floating displays that need to stay out of the way while delivering focused information. But here's where it gets even more powerful: since width and height are Dynamic Properties, you can make your "fixed" overlays responsive. Using the Dynamic Property Device Size, you can set different overlay dimensions for tablets versus large industrial displays. Small details, big impact.

Audit Trail – a Flight Data Recorder for Your HMI​

Transparency and security are of vital importance when automating processes. In many industries it is essential to track changes made to a machine, especially where compliance with regulatory frameworks such as FDA 21 CFR Part 11 is mandatory.

We are excited to take the next step in making life even easier for HMI engineers with the Audit Trail. You can begin integration straight away with the new Audit Trail Page and the Audit Trail Settings or read our detailed guide for more information.

If you are building machines and HMIs that need to comply with FDA 21 CFR Part 11 take a look at our guide on how HELIO can help.

Sneak Peek: The HELIO SDK – Built for Ambitious Projects​

Our standard library already offers many options for common use cases. However, we understand that sometimes you need to add new solutions to meet specific requirements.

We are almost ready to fully take the wraps off one of our most requested features: Starting this fall, you'll be able to use the HELIO SDK to develop extensions containing your own controls or pages and integrate them with the HELIO system!

Building on our highly extensible core architecture, we have carefully designed APIs that allow you to start quickly while also scaling for large teams and long product cycles.

To us, product development is about safely adapting to changing requirements. The SDK embodies this focus with its emphasis on type safety and built-in migration support. Written entirely in TypeScript, you're able to build HELIO extensions that are statically verified by the TypeScript compiler and will behave predictably at runtime. Evolving those extensions over time is also very easy. HELIO can automatically migrate projects to new extension versions using our built-in data migration tools.

We are also integrating support for automatic testing tools that allow you to verify a control's behavior and appearance. By using libraries like Storybook and Vitest, which have become the gold standard in web development, you can create even highly complex UIs and make changes with confidence.

All these tools are essential for enabling sustainable projects that can scale to large teams and organizations and will support you in creating great software for your users.

We are currently beta testing this feature internally and with select customers. We look forward to sharing more about it over the coming months.

If you want to learn more about the HELIO SDK, feel free to reach out to us for a demo presentation.

Multi-Line Trend Element – Compare What Matters​

The Trend Element has been updated to support multiple trend lines in a single graph, allowing you to compare different related values with ease.

This saves screen space and helps operators easily identify relationships between data, such as how temperature changes affect pressure or how to compare multiple production line outputs at a glance.

Less Hunting Through Data – Enhanced States Using Enumerations​

The Collection Page now supports enhanced visualizations through Enumerations. Instead of scanning through endless rows of similar-looking data, you can now use colors, custom icons, and cell highlighting to instantly communicate status and quality.

This means outliers and critical items jump out immediately – whether it's a machine running hot, a batch that needs attention, or equipment due for maintenance. Less hunting through data, more time acting on what matters.

Take Control of the Details​

HELIO 25.2.0 also introduces a new option to the Detail View of your Collection Pages that will give you more control on how the details will be displayed:

Details as Overlay

Details as Side Panel

Enhanced URL Parameter Support – Tailored HMIs Without the Tailoring Headaches​

URL Parameters are a very versatile tool to achieve a lot of flexibility for HMIs. They allow you to pass data from the outside into your HMI, enabling powerful customization scenarios. For example, you can define a parameter that identifies different panel locations at your machine, allowing the same HMI to adapt its behavior based on where it's being used.

With HELIO 25.2.0, we're introducing two new dynamic properties that you can use to create more dynamic HMIs that adapt to their usage context and the people using them:

• Is URL Parameter Set allows you to check whether a specific URL parameter has been provided, enabling conditional logic in your HMI design.
• URL Parameter Value lets you directly access and utilize the values passed through URL parameters in your dynamic property configurations.

Self-Explaining Icons​

We take great care of our steadily growing icon family. However, finding the right icon in such a large collection is quite challenging. That's why, from the beginning, we have added metadata to icons to make them more discoverable.

With that in mind, HELIO 25.2.0 introduces an icon tooltip while scanning through the icon library to provide more context to icons quickly. The tooltip features an icon's name and additional tags that provide more information.

Improved Unit Conversion & Value Scaling – One HMI, Every Market​

Unit conversion & value scaling have been part of HELIO for a while, but we've made it much easier to set up. When you're shipping machines to both Europe and the US, your operators shouldn't have to think in foreign units – whether that's °C to °F or bar to PSI.

We've reorganized the interface to make source and target units clearer and added helpful conversion examples so you can set up localized HMIs without the guesswork. Build once, deploy everywhere.

Unbreakable Workflows​

We've enhanced Page Groups and Tab Groups to allow for nesting, enabling page groups to be placed within tab groups and vice versa. This facilitates effective workflow navigation, assisting users in navigating multistep processes.

HELIO intelligently adapts the UI to various display sizes, allowing your product team to design a single workflow that functions perfectly, regardless of the panel size operators are using.

Project Export With Translations – Simplified Target Device Commissioning​

Getting projects onto your target device has become even easier: We've streamlined project deployment by letting you include all translations directly in your project export.

Plus, we've added a new guide Commissioning to Target Device to walk you through the entire deployment process.

Sneak Peek: Personalization With Zoom​

Industrial environments are as diverse as the people who work in them. Operators bring various experiences and preferences to their daily interactions with machines. Furthermore, HMIs are expanding to new output devices, such as large TV screens. This diversity of people and devices underscores the need for more accessible and adjustable interfaces. This concept is commonly referred to as accessibility, and we have been working diligently to integrate it into HELIO.

In upcoming versions, we will introduce a variety of new Personalization features. The Zoom, by far the most frequently requested personalization feature, will be released first. It allows operators to adapt HMI elements to their particular needs or the device they're using.

When working in challenging conditions – whether it's viewing from a distance, or simply needing larger interactive elements for easier operation – operators can now make buttons, text, and controls bigger. Also, if you need to monitor more data points at the same time, you can now make your HMI smaller so that more information fits on the screen.

The new Zoom feature will ship this fall. If you're interested in trying it out, get in touch with our team.

Icons​

Our design crew has also added 46 new icons to the HELIO Icon Set, bringing the total to a whopping 1,138. 🎉

“Claiming that software is bug-free is simply not realistic. Let's be honest: there will be bugs. What matters is how we deal with them. Do we get frustrated, or do we take the opportunity to improve our product and move forward? We as a team are committed to continuous improvement and put a lot of work into our architecture and infrastructure to be able to do just that: to keep making HELIO better, one step at a time.”

In this spirit, we're releasing HELIO 25.1.1 - our second patch release of the year and the first patch for HELIO 25.1, that we've released a month ago.

Changelog​

Improved

We're thrilled to let you know that we've rolled out HELIO 25.1.0, the first release of 2025, which is now available for everyone to use.

Highlights​

Let's dive into the highlights of this release…

OPC-UA Stability: A Big Step Forward​

We know how frustrating it can be to work with OPC-UA when connections are not stable. Many of our customers have shared such experiences with us, and there are several reasons for these instabilities.

The main reason is that older PLCs were simply not designed to handle complex multi-threaded applications. But modern distributed client-server architectures make them do just that. Now they have to run the OPC-UA server on top of their existing workload. And of course, these servers want to use as few resources as possible on their clients. This can turn into a problem if the PLC program is complex and requires all the resources for proper execution.

That's why we focused on OPC-UA stability in this release. We took those concerns to heart and invested time and effort into improving the stability of our data layer. We analyzed patterns, ran test suites, and focused on communicating with low-end PLCs.

We've been able to address lots of issues and make connections more resource efficient. The result? More reliable and stable connections to OPC-UA PLCs for you with HELIO 25.1.0.

Secure Connections Over OPC-UA​

If you've done it before, you know how tricky it can be to set up a secure connection with OPC-UA. Generating certificates, understanding the lingo and the laborious process of figuring out all those little details and settings can be a real pain. 😤

←→

Again, we've put a lot of thought into this, tested many different server configurations, and explored the depths of the protocol. So we're pleased to report that HELIO 25.1.0 now allows you to easily establish signed connections with OPC-UA servers. 💪😎

Of course we're not done yet, so keep the feedback coming! But we do think this is a major step into the right direction.

Message Type Export & Import​

We are also enhancing our new Message View with the ability to export and import message types as CSV or JSON files. This is especially useful for customers who need to define a large number of message types, as these types are often created automatically. You can now convert these lists into CSV files and import them into HELIO.

←→

New Checkbox Element​

We've added a new checkbox feature that lets you switch between true and false values with a checkmark instead of a switch button. Also, the Magic Input Element now shows the Control Type property when linked to a boolean variable. This gives you the flexibility to choose the control type that best suits your use case

Streamlined Container Properties​

Hooray for consistency! We've improved the properties for Label, Icon, and Description for controls and inputs.

We've grouped them together across different elements, such as Button, Magic Input and Magic Output, into a unified and consistent property group called Container.

Improved License Transparency​

We've enhanced the HELIO Runtime License feedback. Now, you can access more information about all the activated licenses and their features within your current HELIO instance.

←→

Translating HMIs Just Got Better​

You can now choose which languages you want to view and compare in the Translation Manager. You can also see which translations have been changed, which is really useful after an import.

And we've improved the translation conflict feedback in the Translation Quick Editor, making it easier to resolve such issues with confidence.

Improved Unsaved Changes Hint​

We've also improved the way HELIO tells you about unsaved changes. Especially when those changes require you to save in order to take effect in the preview.

HELIO Update Notifier – Because the Best Is Yet to Come!​

As we said, we're not done yet. In fact, we've got a lot of great stuff planned for our roadmap. So we want to make sure you're always in the loop. So now, when you open the Project Editor, HELIO will check for updates and let you know about them.

⚡ Faster Trees – IDE Performance Boost​

Finally, the HELIO IDE is now faster than ever. The trees within the IDE that do most of the heavy lifting, e.g., rendering thousands of data variables, got a performance update with this version.

Floating Towards Improved Overlays​

We've taken one of our favorite features - the Open Page as Overlay action - and turned it up a notch. Now you can open overlays that float above the rest of the page and are anchored to the element that initiated the action. This opens up som possibilities for adding additional functionality, like popup menus or in-place editors for numeric input.

Check out the brand new v24-2 Showcase project template to see floating overlays in action:

Performance & Stability​

In addition to the new features, we have implemented substantial changes to enhance the performance and stability of HELIO 24.2. We are proud to announce that HELIO is now running on Rust, which has significantly improved its efficiency and speed, allowing it to run stably on less powerful target devices. In initial tests, these improvements have reduced the CPU and RAM usage of the HELIO Runtime by up to 90%.

Revamped And Lightning-Fast OPC UA Stack ⚡​

We have chosen the fast open62541 library, written in C, as the foundation of our new OPC UA Connection. This is where Rust really shines since it is a programming language that allows us to make use of high-performance, low-level libraries without sacrificing safety.

Open Source at Heart​

Being consumers of Open Source & Free Software ourselves, we think that this is a great opportunity to give back the community. That's why we've released our Rust crate under an Open License that allows others to use and contribute to it.

Built-in Support For Unit Conversions​

Working with different units of measurement is a common challenge in industrial control systems. There are many reasons why unit conversions are necessary, but a key factor is localization: different countries use different measurement systems.

That's why we've made unit conversions first-class citizens in HELIO 24.2.

The new version's first notable detail is its name: 24.1, a departure from the previous release, 13.0. What's the reason behind this?

We aim for simplicity in every aspect of our product, including version names. However, our previous versioning scheme had some drawbacks. An incrementing version number lacks context, making it hard to remember and distinguish. Look at popular browsers, for instance. A lot of them have a version names like 123.0.6312.29. Can you understand what this version signifies? It's quite challenging, isn't it?

To address this, HELIO releases will now use a versioning system based on the year and an incrementing version number, like 24.1, 24.2, etc. This approach provides immediate context: the release year and how much older the current version is. We're pleased with this change and believe you will appreciate it, too!

Starting this year we are also introducing a new release cadence. As we continue to expand the capabilities of HELIO, we want to ensure that you can benefit from new features and improvements frequently. Therefore, we are moving to a quarterly release cycle. This means you can expect a new version of HELIO every 3 months, packed with new features and improvements.

That's why we are proud to announce the launch of our new documentation platform. We take great care to ensure that HELIO is as user-friendly as possible and this also extends to our documentation.

More Direct Editing – Our Preview Just Got a Context Menu​

Our preview area has learned a new trick. You can now right-click on any element to open a context menu allowing you to quickly edit or delete the element. You can even add new elements directly from the context menu. This makes it easier to work with the preview and speeds up your workflow.

Meet the Value Bar Element – Help Operators to Better Classify Values​

Get ready to meet the new Value Bar element. This element is perfect for showing values in a more visual way. It allows you to display a PLC value as well as its range and current state in one element. This makes it easy for operators to quickly classify values and understand their meaning.
