- Bugfix device status was not set in MODBUS registers



V 1.06.1 (2024-03-26)
- Fix issue with setting NONE parity in MODBUS mode



V 1.06.0 (2023-05-30)

- "unit for temperature" (°C / °F) has been added to the reply to the ASCII command "I".
- Modbus protocol (RTU) has been integrated.
- Advanced SDI-12 commands to configure the Modbus protocol have been added.



V 1.05.0 (2022-07-27)

- Improved system stability to avoid unnecessary system resets
- Improved SDI-12 communication.
- DWD protocol timestamp bugfix.
- Remove write protection from SDI-12 commands listed in manual

- Compatible to new Pluvio processor generation (k2, k4 mainboards) that are available since July 2022.



V 1.04.0 (2021-06-24)

- RS-485 command line mode (ASCII text retrieval): Added field separator when outputting measured values with a checksum (CRC) (there is now a separator character in front of the checksum; e.g. ";").
- SDI-12-communication revised (version 1.04.0 prevents the occurence of temporary SDI-12 data gaps).
- Stability of the measured values "Accu RT-NRT" improved.
- For devices with a production date before quarter 4,2019: stability of temperature compensation improved
- Various minor bugfixes and firmware optimizations



V 1.03.0 (2018-05-24)

- Measured value processing optimized to prevent the registration of erroneous precipitation
