- Firmware for Pluvio²L, Pluvio²S
- This firmware version is not suitable for OTT Pluvio² (former generation of devices)!

V 1.06.0 (30.05.2023)
- Add temperature unit to ASCII I-Command response
- MODBUS protocol integration
- Add SDI-12 commands for MODBUS protocol configuration



V 1.05.0 (15.07.2022)
- 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
