Changelog

2.21.0

2026-04-16

Highlights

Version 2.21.0 brings a complete run data export: measurement data can be downloaded as CSV via configurable runs. A new Gateway reconnect mechanism additionally enables manual restoration of connections directly from the user interface.

New Features

Run Export — Runs can be downloaded as a CSV file. The interface shows all completed runs and provides direct download access to the exported data.
Run Configuration — Runs can be created and configured via the interface. Supported trigger types: alarm trigger (with pre and post time), external trigger (start & stop), time trigger (start & stop), and interval trigger. Existing configurations can be activated and deactivated.
Variable Path in Run Configuration — Run variables now support an additional parameter for the full group path to the variable (e.g. Device3/Group2/Variable12).
Gateway Endpoint Reconnect — When connection problems occur, the connection of a Gateway endpoint can be manually forced via the interface. The broker configuration is updated before the reconnect. Connection status and endpoint details are directly viewable.
Gateway Insights: Extended System Data — The system now transmits additional device information to the Hub: device ID, software version, MAC addresses, manufacturer, serial number, and the available storage space of the database partition.

Bug Fixes

Run without Variables — A run without defined process variables caused an error during CSV export. The run is now no longer activated if no variables are stored.
Email Notifications for Alarms — Email notifications for Grafana alarms could no longer be sent after version 2.18, as the underlying system service was no longer available. The device name is now correctly retrieved via the new OS service.
Run Interval Initialisation — Interval-type runs were not correctly initialised when created: the start time was not set and the first data record was skipped.

Breaking Changes

Restart required — This update automatically triggers a device restart. When updating from version 2.20, the system also validates that the required DEB Crawler Packs are installed.

2.20.0

2026-03-03

Note: System restart required This update requires a system restart. The restart can be performed at any time, but must occur before a further update is applied.

The update includes a pre-installation validation of the installed packages (prerequisite: version 2.19). If the validation fails, the update process is aborted — no changes are made.

Highlights

Version 2.20.0 introduces the OPC UA connector: connection to OPC-UA-capable devices with secured connection, variable explorer, and status display. Several bug fixes in the OPC and Gateway areas improve stability.

New Features

OPC UA Connector — Connection to OPC-UA-capable devices is now possible. The connector supports gradual exploration of the device variable tree (no pre-loading of the full structure), secured connections with password authentication, and all common data and access types (Bool, String, DateTime, Array, etc.).
OPC Quick Insights — Connection status, error messages, and warnings from the OPC connector are displayed in the Quick Insights view, analogous to the Simatic connector.
OPC Performance Test — The performance test button for the OPC connector is now active and delivers valid test results.
Device ID (Crawler ID) — Each device receives a unique UUID, which is provided via the system info route. This ID enables reliable assignment of the device in Hub and Companion.
Updater: Subversions — Update bundles can now set a subversion without incrementing the main version. This enables individual components or special features to be retrofitted.

Bug Fixes

OPC: Password Change on Device — A password change on the OPC device was ignored after the first time and only took effect after a container restart. The cause was a faulty deduplication of configuration messages.
OPC: Reconfiguration of Variables — Changes to variables (e.g. interval, activation) were not applied by the connector. Configuration events are now processed correctly.
OPC: Incorrect Performance Test Result — The performance test did not return a valid result when the sampling rate could not be achieved. The result is now correctly reported as failed.
OPC Quick Insights: Unclear Messages — Status messages for connection and password issues were partially unclear. The messages have been revised and aligned with the format of the Simatic connector.
Gateway: Send Switch Required Restart — The switch in the MX Dispatcher area for controlling the send process only took effect after a device restart. The change is now applied immediately.

Breaking Changes

Upgrade from v2.19 only supported. Ensure v2.19 is fully installed before applying this update.

2.19.0

2026-01-30

Note: Automatic restart This update automatically restarts the device immediately, as the new updater is required for the second installation step.

The update includes a pre-installation validation of the installed packages (prerequisite: version 2.18). If the validation fails, the update process is aborted — no changes are made.

Highlights

Version 2.19.0 brings extensive improvements to the Simatic connector: faster connection establishment, gradual exploration without pre-loading the full structure, and optimised RAM usage. The user interface has been extended with status-dependent controls and a clearer variable structure.

New Features

Simatic: Gradual Exploration — The variable structure of a Simatic device is now loaded incrementally, without downloading the full structure upfront. This prevents crashes with large program structures and significantly reduces RAM usage.
Simatic: Direct Data Block Addressing — Data blocks are now directly accessible without overlaid group levels.
UI: Variable Structure — Arrays are explicitly labelled as arrays in the variable explorer (displaying the array size). Data blocks and group structures are sorted alphanumerically.
UI: Status-dependent Control Lock — The performance test and import-from-device functions are locked while no connection to the device is established.
Configuration Migration — A separate update package is available for devices with an existing variable configuration, which migrates the configuration to the new Simatic format. Note: after the migration, Grafana dashboards must be reconfigured.
Updater: Script Execution — The update system now supports pre- and post-installation scripts that are executed as part of an update bundle.

Bug Fixes

Simatic: Slow Connection Establishment — Connection establishment to the PLC could take up to 5 minutes on some devices. Connection handling and status display have been completely redesigned.
Simatic: Performance Test Returned Invalid Results — The performance test did not return valid results when the sampling rate could not be achieved. Results and code structure have been revised.
Simatic: Password Protection Always Active on Creation — When creating a new Simatic device, password protection was always pre-selected, even when no password was entered.
Simatic: Disabled Exclude List Ignored Variables — A disabled exclude list caused temporarily unavailable variables to be permanently ignored. The exclude list is now always active and configurable via parameters.
Simatic: Health Status with Wrong Password — After a password change with an incorrect password, the health status was not correctly set to “Unhealthy”. Only a restart of the connector restored the correct state.
NTP: Service Inactive after Restart — The NTP service switched off after a system restart.

2.18.2

2025-12-05

Critical Patch — Updater Depending on the hardware in use, larger update packages could not be fully uploaded. The upload was aborted with a timeout.

Highlights

Version 2.18.2 fixes an issue where the upload of larger update packages timed out depending on the hardware. A full fix of the underlying issue in the API service will follow in version 2.19.

Bug Fixes

Updater: Upload of larger packages failed — Depending on the hardware configuration, the high system load during the upload caused the process to abort with a timeout, and the update package was not fully transferred. The upload is now forwarded directly to the updater service.

2.18.1

2025-11-08

Critical Patch — Gateway Without this patch, the Gateway service could not retrieve the device’s hostname, which is required to authenticate with the cloud. The Gateway function was therefore completely out of service.

Highlights

Version 2.18.1 is a critical patch that restores the Gateway connection to the cloud.

Bug Fixes

Gateway: Connection to cloud interrupted — After the infrastructure overhaul in version 2.18, the Gateway service could no longer retrieve the device’s hostname. The Gateway connection to the cloud was therefore completely interrupted.

2.18.0

2025-10-09

Note: Two restarts required This update requires two consecutive restarts, as OS components and the Linux kernel are also being updated.

The update includes a pre-installation validation of the installed packages (prerequisite: version 2.17) as well as a check of the available storage space. If either check fails, the update process is aborted — no changes are made.

Highlights

Version 2.18.0 brings a completely redesigned update interface and a new Docker infrastructure that enables direct updates of individual components. Network configuration and discovery have been extended for the Companion app. Several stability issues in the Simatic connector have been resolved.

New Features

Updater: New Interface — The updater features a completely redesigned user interface with an update history and a dedicated process page. Available storage space is checked before the update.
Setup Wizard: Input Validation — Invalid inputs are caught and reported immediately during the setup process.
Network Configuration (Initial Setup) — Network interfaces can be configured via the initial setup.
Discovery: Extended Device Information — The Discovery service displays additional fields for discovered devices.
Firmware Update via Companion — The foundation for firmware update functionality via the Companion app has been implemented.

Bug Fixes

Simatic: High Memory Load — The Simatic connector caused uncontrolled memory consumption under certain conditions. The fix from patch 2.17.1 has been incorporated into this version.
Simatic: Exclude List Ignored Variables — A faulty exclude list implementation caused variables to be incorrectly ignored.
Simatic: NaN Error in Quick Insights — When querying the device ID, a NaN error occurred that caused incorrect displays in Quick Insights.
IO Load Problem — A problem with elevated IO load that had existed since version 2.16 was resolved by adjusting the Influx configuration.
CSV Config Import: Invalid Characters — Invalid characters in the address field are now caught during CSV import.

2.17.1

2025-08-28

[!CAUTION] Critical Patch — Simatic Connector This patch should be applied to all crawlers promptly. The bug can lead to a complete failure of the crawler, as the Simatic service consumes the memory available to other applications.

Background

During the connection establishment to the PLC, the Simatic service was consuming an excessive amount of memory. As a result, other services no longer had sufficient memory available, which could lead to a total failure of the crawler.

2.17.0

2025-03-17

Note: System restart required This update requires a system restart because duplicates in the core Compose configuration are cleaned up. During the restart, all affected containers will be recreated.

Highlights

Version 2.17.0 brings extensive enhancements to the Simatic connector: live view, quick preview, password protection, and Quick Insights. The Modbus connector has been extended with IP address change and endianness configuration. The user interface has been updated with a revised navigation menu and improved connection status display.

New Features

Simatic: Live View — The most recent measured value of a variable is displayed directly in the variable browser.
Simatic: Quick Preview — Fast time-series preview of a variable’s value as a chart, accessible directly from the browser.
Simatic: Password-protected Devices — Connections to password-protected Simatic devices are supported.
Simatic: Quick Insights — Dynamic connection status and log messages are displayed directly from the Simatic service.
Simatic: Improved Timeout Behaviour — The connection timeout behaviour on connection drops has been revised.
Modbus: Change IP Address — The IP address of a Modbus device can be changed afterwards without having to recreate the device.
Modbus: Configurable Endianness — Big-endian and little-endian are configurable at the device and variable level.
UI: Restart Source Extensions from UI — Simatic and Modbus containers can be restarted directly from the interface.
UI: Navigation Menu — The navigation menu has been revised and improved.

Bug Fixes

WebUI does not start after device restart — The user interface did not start correctly after a restart of the crawler.
Error during Initial Setup — An error occurred when setting up the device for the first time.
Gateway Manager: Configuration Delivery — The configuration was not correctly delivered to the Gateway Dispatcher (affects only installations with the Gateway function enabled).

2.16.1

2025-02-26

Critical Patch — Gateway After a system restart, no measurement data was being sent toward the cloud. The Gateway function was therefore completely out of service.

Highlights

Version 2.16.1 is a critical patch that restores Gateway data transmission after a device restart.

Bug Fixes

Gateway: Data not sent after restart — After a system restart, continuous measurement values were no longer transmitted to the cloud. Structural data and insights were sent correctly; only the measurement data was missing. The issue could only be worked around by manually changing a variable on the Gateway.

2.16.0

2025-02-06

Note: Database restarts — brief data loss possible This update restarts the databases. A brief period of data loss will occur as a result. This is technically necessary due to the included database migrations.

Note: This update includes the changes from patch 2.15.1 and can be applied directly on top of version 2.15.0.

Highlights

Version 2.16.0 introduces controlled transmission of measurement data via the Gateway trigger. IO load problems from earlier versions have been permanently resolved.

New Features

Gateway: Controlled Dispatching (Conditional Dispatching) — When the Gateway is enabled, variables can be selectively sent to the cloud via a source trigger instead of transmitting continuously.
Variables: Cascading Deletion — When a device or group is deleted, the associated variables are automatically deleted along with it.

Bug Fixes

IO Load Problem — An excessive IO load that had been known since earlier versions was permanently resolved by adjusting the InfluxDB configuration and introducing resource limits.
