Software Update – new version 2.1.1 (11/09/2025)
Important notes:
If ARNI is updated from 2.0.9 to 2.1.1, the update overwrites the LEPMON code and the GPS coordinates. Please note down the coordinates before the update and re-enter them in the menu after the update. When updating from 2.0.10 or newer to 2.1.1, this information is retained, but should still be checked.
Users whose district code contains an umlaut (Ä, Ö, Ü) and is three characters long should update from 2.1.0 to 2.1.1.
ARNIs with older software versions can be updated directly to 2.1.1.
What’s new
- Fixes an issue where ARNI does not correctly read the district code when it consists of 3 letters and one of these letters is an umlaut (Ä, Ö, or Ü)
- Replaces the term “Trap” in the CSV file, the log file, and other parts of the interface
Hardware Update
ARNI can be retrofitted with a modified USB cable to switch the camera on and off and thus save power. We will inform users about the replacement. All ARNIs delivered from September 2025 onward already have this cable installed.

Operating Manual
The operating manual for the third generation of ARNI includes step-by-step instructions on safety notes, camera setup, and operation with the latest software. In case of errors, it provides first aid on site. We recommend downloading the manual and carrying it with you during ARNI field maintenance, for example on your smartphone.
ARNI can be operated with PV modules. For this purpose, we provide charge controllers from Victron Energy. A detailed manual is available on the product website. For maintenance, the load output should be set to 24H. During normal operation, L (“Dusk2Dawn”) is sufficient to save power.
