You’re managing a network of IoT sensors that monitor air quality across multiple locations. Suddenly, one of the sensors goes offline, but you don’t notice until hours later. The result? A gap in your data and a missed opportunity to take corrective action. This is a common challenge when working with IoT devices: staying informed about the real-time status of each device is crucial to ensure smooth operation and timely troubleshooting.

This is where Device Status Notifications, the latest feature in the Arduino Cloud, comes in. Whether you’re an individual maker or an enterprise, this feature empowers you to stay on top of your devices by sending real-time alerts when a device goes online or offline.

What is “Device Status Notifications?”

Device Status Notifications allow you to receive instant alerts whenever one of your devices changes its connectivity status, whether it’s going offline or coming back online. You can customize these alerts for individual devices or all devices under your account, with the flexibility to exclude specific devices from triggering notifications.

We announced it a while ago, Arduino Cloud already supports Triggers and Notifications, allowing you to create alerts based on specific conditions like sensor readings or thresholds. With the addition of Device Status Notifications, you can now monitor device connectivity itself. This means you can now receive an alert the moment a device loses connection, providing a proactive way to manage your IoT ecosystem. For more details on the original feature, check out our Triggers and Notifications blog post.

Key benefits for users

• Real-time monitoring: Get notified instantly when a device disconnects or reconnects, helping you take corrective actions promptly.

OPC Unified Architecture – OPC UA in short – is a cross-platform, open-source machine-to-machine communication protocol for industrial automation. It was developed by the Open Platform Communications (OPC) Foundation and is defined in detail in the IEC 62541 standard.

With the release of the Arduino_OPC_UA library we enable users to convert any product from our Arduino Opta range into an OPC UA-enabled device. 

Step-by-step guide to setting up OPC UA on Arduino Opta

It’s as simple as uploading a single sketch onto your Opta and connecting it to an Ethernet network. Once uploaded, the OPC UA firmware exposes the Arduino Opta’s analog and digital inputs, the user button and LED (only Arduino Opta WiFi), as well as its relay outputs as properties that can be read from or written to using OPC UA. OPC UA communication is performed using OPC UA binary encoding via TCP sockets.

Arduino_OPC_UA is a port of the Fraunhofer open62541 library implementing IEC 62541 in highly portable C99 for both Windows and Linux targets. One serious challenge during the porting of open62541 was to decide on sensible tradeoffs concerning RAM consumption, as using OPC UAs full namespace zero (NS0) requires up to 8 MB of RAM while the STM32H747 powering the Arduino Opta has a total of 1 MB of SRAM to offer – some of which already allocated by the the Arduino framework for the Arduino Opta.

Expand functionality with Arduino Opta Modules and OPC UA integration

Additionally, Arduino_OPC_UA supports the automatic discovery, configuration and exposure as OPC UA objects of the recently released Arduino Opta expansion modules. Currently three different expansion modules exist: Arduino Opta Analog Expansion (A0602), Arduino Opta Digital Expansion with electro-mechanical relay outputs (D1608E), and with solid-state relay outputs (DS1608S). During system start-up, the Arduino Opta’s expansion bus is queried for connected expansion modules and automatically configures them and brings them online for interfacing via OPC UA.

You can extend the default OPC UA server to add additional OPC UA properties such as data collected from a sensor device connected to the Arduino Opta. As a demonstration, we’ve created an example showing how to collect temperature and humidity data from a Modbus RTU device (connected to the Opta’s RS485 port) and subsequently expose this data via OPC UA properties.

How will you use the new Arduino_OPC_UA library? Let us know in the comments below or share your newest projects on Project Hub!

TrueNAS Electric Eel (SCALE 24.10) is now feature-complete with the availability of the first Release Candidate. TrueNAS SCALE 24.10-RC.1 is now available for download, or update directly from within your existing TrueNAS installation. As always, please carefully read the Release Notes before deploying or updating your system.

Electric Eel emerged into the BETA stage on August 29th. In the last four weeks, a record number of users have volunteered to test Electric Eel and explore the new Docker-powered App capabilities. The Electric Eel uptake rate is over 3X Dragonfish and over 10X the 13.3 BETA versions.

The BETA process has proven that in-place App migration from Kubernetes to Docker will work for the existing catalog applications, with user data preserved. As of RC1, we have reached 100% in the Porting and Migration progress, as tracked on our GitHub Apps page. All previous Apps have been ported for new installs under the Docker framework, and users with existing Kubernetes-based installations from Dragonfish can automatically migrate during the TrueNAS upgrade process. Shout-out to our amazing Apps engineering team, as well as the community members who helped us test the migration processes during BETA. With this important migration milestone reached, we can now turn our attention to adding new Apps and Features in the coming months.

In addition to achieving parity between the old and new App catalogs, Custom Apps deployed under Dragonfish and earlier as Docker images can now be migrated to the native Docker framework in Electric Eel. More advanced settings such as manually installed Docker provisioning in a systemd-nspawn container using the community Jailmaker will need to be manually migrated.

What’s new in Electric Eel RC.1

We’d like to extend our thanks to our community members who jumped into the BETA release with both feet, eagerly testing, reporting, and helping us correct bugs. Our first BETA version was a success, and today’s RC.1 has 200 additional fixes and improvements.

Building on our community feedback, the engineering team has made several major improvements and has now completed the Electric Eel feature set. New functionality and changes in 24.10-RC.1 include:

• Login Alerts on root/admin user login or attempted login
• App logs are better captured and displayed in the UI
• Improved App Info cards (now with links)
• App Utilization (CPU/Memory/Network/Disk IO) displayed on the Apps page
• New Dashboard is completed with better mobile support. The legacy “Old Dashboard” has been removed.
• Custom App YAML Editor allows for custom application configurations to be deployed. (If a GUI is desired, we suggest deploying the built-in Portainer App.)
• Custom App Migration is enabled for users who deployed Docker images in Dragonfish and earlier using the “Custom App” UI option
• NVIDIA drivers are now handled in a more modular manner, and can be installed dynamically post-installation

Install the new modular NVIDIA drivers from the Apps -> Settings Page in 24.10

One of the major anticipated features of the Docker framework in Electric Eel that users have expressed interest in is the YAML editor for advanced Apps configuration. In 24.10-RC.1, the Custom App YAML editor now allows more complex Apps to be created and deployed through editing of the configuration file. For RC1, the ability to allocate a unique IP address for an installed App is not yet present. This functionality is planned as an App infrastructure update after the RELEASE version of Electric Eel is completed.

With BETA completed and now RC.1 released, the total feature set of Electric Eel can be summarized. We’re looking forward to more feedback (and bug reports!) from our community.

You can look forward to more blog posts and emails highlighting these new features and upgrades in 24.10 – while many of them are already present in RC.1, some of these features won’t be ready until RELEASE, while others such as Fast Deduplication are labeled as Experimental and should be handled with care by early adopters and testers only.

With Electric Eel now feature-complete, the TrueNAS engineering team is focused on the development of the next release, “Fangtooth” in mid 2025. More information will be available at the end of 2024. Many thanks to those who submitted, and voted for, the Feature Requests that have already been adopted. If you have a specific feature or functionality that you feel would benefit TrueNAS, please feel free to submit it on our Community Forums, and vote for other suggested features to help us enhance 24.10 and beyond.

When Should I Migrate?

If you are deploying a new TrueNAS system, we recommend TrueNAS SCALE Dragonfish 24.04.2.2 for:

• Added functionality over CORE
• Vastly broader hardware support
• Expanded App catalog (which will migrate to Electric Eel)
• Sandboxes provide jail-like capabilities using systemd containers
• Better performance on most workloads
• Improved web UI makes managing TrueNAS easier than ever

Dragonfish users can easily update to Electric Eel RC.1 when desired, but at this point we only recommend it for early adopters. We recommend users review the TrueNAS Software Status page for advice.

If you’re ready to explore the Electric Eel Release Candidate, grab it from our downloads page now – and stay tuned for the upcoming full release!

Following up on his successful Doom port last year, engineer Nicola Wrachien – who works at Silicon Labs, a leader in secure, intelligent wireless technology for a more connected world and long-time Arduino partner – has now tackled an even bigger challenge: porting Quake, the iconic 1990s’ first-person shooter, to an Arduino gamepad. 

What a great warm-up for the upcoming Matter Challenge! If this kind of project sounds like fun, follow the competition or submit your own entry by October 31st. 

Sponsored by Mouser Electronics, Silicon Labs and Arduino, the Matter Challenge is open to all skill levels. Take the opportunity to inspire others, by creating an incredible project with the Arduino Nano Matter board.

Released just three years after Doom, Quake was a huge leap forward in gaming technology. It introduced full 3D environments complete with dynamic lighting effects, and its enemies and weapons were 3D models rather than 2D sprites. The game also featured a scripting engine that gave modders a lot of creative freedom. But with more realistic graphics, a particle engine, and more complex sound effects, Quake was also a far bigger technical challenge to port.

Tackling this project required Wrachien to level up on memory and speed constraints. If you want to dive deeper into these challenges, be sure to check out the dedicated post on the Silicon Labs community blog.

In the face of demanding requirements, Wrachien turned to the Arduino Nano Matter, developed with the powerful Silicon Labs® MGM240S as part of a partnership to better enable seamless development of Matter over Thread applications on the Arduino platform, which also led to the release of Arduino’s first-ever Matter software library earlier this year. 

Reflecting on the Arduino Nano Matter board, Wrachien said: “The Nano Matter board, featuring the Silabs xG24, offers impressive processing power and versatility in a compact size, making it a fantastic tool for both simple and complex projects like this one.”

If you’re intrigued and want to explore more technical details, dive into Wrachien’s full post and get into the nitty-gritty of this remarkable project on his blog. You can get your Arduino Nano Matter from our store and replicate his idea thanks to all the information he shares, or imagine a new challenging project of your own!
